This document compares the performance of three routing protocols for mobile ad hoc networks (MANETs): AOMDV, AOMDV with location information using the DREAM protocol, and AOMDV with energy information. AOMDV is a multipath routing protocol that finds multiple disjoint paths between nodes. AOMDV with DREAM uses location information to route packets more efficiently. AOMDV with energy information selects paths based on the residual energy of nodes to improve energy efficiency and network lifetime. The document provides an overview of these three protocols and reviews previous work comparing their performance based on metrics like energy consumption, packet delivery ratio, and throughput.
M-EPAR to Improve the Quality of the MANETsIJERA Editor
In MANET, power aware is important challenge issue to improve the communication energy efficiency at individual nodes. We propose modified efficient power aware routing (M-EPAR), a new power aware routing protocol that increases the network lifetime of MANET. Designing a power aware routing algorithm or technique is one of the most important point considered in Mobile Ad Hoc Networks. These nodes are driven by reactive protocols where broadcasting is mandatory to form a path between two nodes. So in case of death of the node resulting out of less battery calls for re-routing. Since many existing techniques focuses on energy aware routing this paper presents combination of energy aware routing merged with link quality determined by packet drop rate. The proposed scheme has outperformed the existing technique in terms of packet delivery ratio, throughput and energy consumption.
MMINIMUM RESOURCE CONSUMPTIONS ROUTING FOR OPTICAL NETWORKSprj_publication
The problem of determining primary and backup paths for survivable optical WDM
networks is considered. Results of various available routing techniques that try to minimize
the combined cost of primary and the backup path are analyzed for the effects on network
parameters such as mean load, variance of the load on route, number of converters required
by the route and the length of the route. The route cost is modelled such a way that it is
extensible to include any new parameter and vary their relative importance. The efficiency of
such wavelength routed networks has been proved to improve for certain parameters, such as
reduction in blocking probability and number of converters required for desired performance.
The routing is enhanced to analyse effect on network parameters for all node full range

GPSFR: GPS-Free Routing Protocol for Vehicular Networks with Directional Ante...ijwmn
Efficient and practical communications between large numbers of vehicles are critical in providing high level of safety and convenience to drivers. Crucial real-time information on road hazard, traffic conditions and driver services must be communicated to vehicles rapidly even in adverse environments, such as “urban canyons” and tunnels. We propose a novel routing protocol in vehicular networks that does not require position information (e.g. from GPS) but instead rely on relative position that can be determined dynamically. This GPS-Free Geographic Routing (GPSFR) protocol uses the estimated relative position of vehicles and greedily chooses the best next hop neighbor based on a Balance Advance (BADV) metric which balances between proximity and link stability in order to improve routing performance. In this paper, we focuses primarily on the complexity of routing in highways and solves routing problems that arise when vehicles are near interchanges, curves, and merge or exit lanes of highways. Our simulation results show that by taking relative velocity into account, GPSFR reduces link breakage to only 27% that of GPSR in the dense network. Consequently, GPSFR outperforms GPSR in terms of higher data delivery ratio, lower delay, less sensitivity of the network density and route paths’length

ENERGY EFFICIENT NODE RANK-BASED ROUTING ALGORITHM IN MOBILE AD-HOC NETWORKSIJCNCJournal
Mobile Ad-hoc Network (MANET) is an emerging technology, infrastructure less with self-organizing, selfhealing, multi-hop wireless routing networks in real time. In such networks, many routing problems arise due to complexity in the network mobility which results from difficulty in achieving energy efficient routing
in the field of MANET. Due to the dynamic nature and the limited battery energy of the mobile nodes, the communication links between intermediate relay nodes may fail frequently, thus affecting the routing performance of the network and also the availability of the nodes. Though existing protocols are not
concentrating about communication links and battery energy, node links are very important factor for improving quality of routing protocols because Node Rank helps us to determine whether the node is within transmission range or out of transmission range through considering residual energy of the node during the routing process. This paper proposes a novel Energy Efficient Node Rank-based Routing (EENRR)
algorithm which includes certain performance metrics such as control overhead and residual energy in order to improve the Packet Delivery Ratio (PDR), and Network Life Time (NLT) from its originally observed routing performance obtained through other existing protocols. Simulation results show that, when the number of nodes increases from 10 to 100 nodes, EENRR algorithm increases the average residual energy by 31.08% and 21.26% over the existing Dynamic Source Routing (DSR) and Energy Efficient Delay Time Routing (EEDTR) protocols, respectively. Similarly it increases the PDR by 45.38% and 28.3% over the existing DSR and EEDTR protocols respectively.

Mobile Ad hoc Networks are highly dynamic networks. Quality of Service (QoS) routing in such networks is usually limited by the network breakage due to either node mobility or energy depletion of the mobile nodes. Also, to fulfill certain quality parameters, presence of multiple node-disjoint paths becomes essential. Such paths aid in the optimal traffic distribution and reliability in case of path breakages. Thus, to cater such problem, we present a node-disjoint multi path protocol. The metric used to select the paths takes into account the stability of the nodes and the corresponding links. The proposed technique is also illustrated with an example.

Wireless Sensor Networks (WSNs)have sensor nodes that sense and extract information from surrounding

delay.Multipath routing is to discover multipath during route discovery from source to sink. Discover
multipath and sending data via these different paths improve the bandwidth and decrease the end to end

A MIN-MAX SCHEDULING LOAD BALANCED APPROACH TO ENHANCE ENERGY EFFICIENCY AND ...IJCNCJournal
Energy efficiency and traffic management in Mobile Ad hoc Networks (MANETs) is a complex process due
to the self-organizing nature of the nodes. Quality of service (QoS) of the network is achieved by
addressing the issues concerned with load handling and energy conservation. This manuscript proposes a
min-max scheduling (M2S) algorithm for energy efficiency and load balancing (LB) in MANETs. The
algorithm operates in two phases: neighbor selection and load balancing. In state selection, the
transmission of the node is altered based on its energy and packet delivery factor. In the load balancing
phase, the selected nodes are induced by queuing and scheduling the process to improve the rate of load
dissemination. The different processes are intended to improve the packet delivery factor (PDF) by
selecting appropriate node transmission states. The transmission states of the nodes are classified through
periodic remaining energy update; the queuing and scheduling process is dynamically adjusted with energy
consideration. A weight-based normalized function eases neighbor selection by determining the most
precise neighbor that satisfies transmission and energy constraints. The results of the proposed M2SLB
(Min-Max Scheduling Load Balancing) proves the consistency of the proposed algorithm by improving the
network throughput, packet delivery ratio and minimizing delay and packet loss by retaining higher
remaining energy.
A RELIABLE AND ENERGY EFFICIENCT ROUTING PROTOCOL FOR MANETs cscpconf
A mobile ad-hoc network (MANETs) is an infrastructure less network in which the mobile nodes
communicate with each other. Due to its various characteristics like highly dynamic topology
and limited battery power of the nodes, routing is one of the key issue. Also, it is not possible to
give a significant amount of power to the mobile nodes of ad-hoc networks. Because of all this
the energy consumption is also an important issue. Due to limited battery power, some other
issues like if some node gets fail, which results in loss of data packets and no reliable data
transfer has been raised. In this paper, an algorithm is proposed for data transmission which
detects the node failure (due to energy) before it actually happens. Because of this network
lifetime gets improved. The proposed routing algorithm is energy efficient as compared to
AODV routing algorithm. The performance is analyzed on the basis of various performance
metrics like Energy Consumption, Packet Delivery Ratio, Network Life Time, Network Routing
Overhead and number of Exhausted nodes in the network by using the NS2 Simulator.
Energy Consumption Analysis of Ad hoc Routing Protocols for Different Energy ...IOSR Journals
Abstract : In Mobile Ad hoc Networks (MANETs), energy conservation is a critical issue as the nodes are powered by the batteries which have limited energy reservoir. Hence the power level of the nodes is a problematical factor that extensively affects the performance and efficiency of ad hoc routing protocols. The rapidly changing traffic pattern the mobility of the nodes and the lack of fixed infrastructure makes routing in a MANET a challenging issue. So one of the main issues in MANET routing protocols is the development of energy efficient and QoS aware routing protocols which requires the energy analysis of routing protocols so that some modifications can be suggested. This paper presents performance comparison of three categories of mobile ad hoc routing protocols i.e. proactive, reactive and hybrid. The performance analysis is based on different metrics of Physical Layer such as Power Consumed in Transmit Mode, Power Consumed in Receive and Idle Modes, and metrics of application layer like Average End to End Delay, Average Jitter, Throughput and Packet Delivery Ratio based on the simulation analysis. Simulation analysis is performed over well known network simulator QualNet 6.1. Keywords - MANET, AODV, DYMO, OLSR, PDR
Optimized Cluster Establishment and Cluster-Head Selection Approach in WSNIJCNCJournal
In recent years, limited resources of user products and energy-saving are recognized as the major challenges of Wireless Sensor Networks (WSNs). Clustering is a practical technique that can reduce all energy consumption and provide stability of workload that causes a larger difference in energy depletion among other nodes and cluster heads (CHs). In addition, clustering is the solution of energy-efficient for maximizing the network longevity and improvising energy efficiency. In this paper, a novel OCE-CHS (Optimized Cluster Establishment and Cluster-Head Selection) approach for sensor nodes is represented to improvise the packet success ratio and reduce the average energy-dissipation. The main contribution of this paper is categorized into two processes, first, the clustering algorithm is improvised that periodically chooses the optimal set of the CHs according to the speed of the average node and average-node energy. This is considerably distinguished from node-based clustering that utilizes a distributed clustering algorithm to choose CHs based on the speed of the current node and remaining node energy. Second, more than one factor is assumed for the detached node to join the optimal cluster. In the result section, we discuss our clustering protocols implementation of optimal CH-selection to evade the death of SNs, maximizing throughput, and further improvise the network lifetime by minimizing energy consumption.
An Efficient and Stable Routing Algorithm in Mobile Ad Hoc NetworkIJCNCJournal
Mobile Ad hoc Network (MANET) is mainly designed to set up communication among devices in infrastructure-less wireless communication network. Routing in this kind of communication network is highly affected by its restricted characteristics such as frequent topological changes and limited battery power. Several research works have been carried out to improve routing performance in MANET. However, the overall performance enhancement in terms of packet delivery, delay and control message overhead is still not come into the wrapping up. In order to overcome the addressed issues, an Efficient and Stable-AODV (EFST-AODV) routing scheme has been proposed which is an improvement over AODV to establish a better quality route between source and destination. In this method, we have modified the route request and route reply phase. During the route request phase, cost metric of a route is calculated on the basis of parameters such as residual energy, delay and distance. In a route reply phase, average residual energy and average delay of overall path is calculated and the data forwarding decision is taken at the source node accordingly. Simulation outcomes reveal that the proposed approach gives better results in terms of packet delivery ratio, delay, throughput, normalized routing load and control message overhead as compared to AODV.
MPR selection to the OLSR quality of service in MANET using minmax algorithmIJECEIAES
Optimized link state routing (OLSR) is a routing protocol that has a small delay, low traffic control, support the application of denser networks, and adopts the concept of multipoint relays (MPR). The problem of OLSR is routing table updating which continually causes excessive packet delivery, and energy consumption becomes increased. This article proposes the improvement of OLSR performance using the min-max algorithm based on the quality of service (QoS) with considering the density of the node. The Min-max algorithm works in selecting MPR nodes based on the largest signal range. The QoS parameters analyzed with a different number of nodes are packet delivery ratio (PDR), throughput, delay, energy consumption, and topology control (TC). Simulation result of network simulator version 2 (NS-2) shows that OLSR performance using the min-max algorithm can increase PDR of 91.17%, packet loss of 60.77% and reduce topology control packet of 8.07%, energy consumption of 16.82% compared with standard OLSR.
Performance comparison of mobile ad hoc network routing protocolsIJCNCJournal
Mobile Ad-hoc Network (MANET) is an infrastructure less and decentralized network which need a robust
dynamic routing protocol. Many routing protocols for such networks have been proposed so far to find
optimized routes from source to the destination and prominent among them are Dynamic Source Routing
(DSR), Ad-hoc On Demand Distance Vector (AODV), and Destination-Sequenced Distance Vector (DSDV)
routing protocols. The performance comparison of these protocols should be considered as the primary
step towards the invention of a new routing protocol. This paper presents a performance comparison of
proactive and reactive routing protocols DSDV, AODV and DSR based on QoS metrics (packet delivery
ratio, average end-to-end delay, throughput, jitter), normalized routing overhead and normalized MAC
overhead by using the NS-2 simulator. The performance comparison is conducted by varying mobility
speed, number of nodes and data rate. The comparison results show that AODV performs optimally well
not the best among all the studied protocols.

Positioning techniques have been a common objective since the early development of wireless networks. However, current positioning methods in cellular networks, for instance, are still primarily focused on the use of the Global Navigation Satellite System (GNSS), which has several limitations, like high power drainage and failure in indoor scenarios. This study introduces a novel approach employing standard LTE signaling in order to provide high accuracy positioning estimation. The proposed technique is designed in analogy to the human sound localization system, eliminating the need of having information from three spatially diverse Base Stations (BSs). This is inspired by the perfect human 3D sound localization with two ears. A field study is carried out in a dense urban city to verify the accuracy of the proposed technique, with more than 20 thousand measurement samples collected. The achieved positioning accuracy is meeting the latest Federal Communications Commission (FCC) requirements in the planner dimension.

In a route reply phase, average residual energy and average delay of overall path is calculated and the data forwarding decision is taken at the source node accordingly. Simulation outcomes reveal that the proposed approach gives better results in terms of packet delivery ratio, delay, throughput, normalized routing load and control message overhead as compared to AODV.
MPR selection to the OLSR quality of service in MANET using minmax algorithmIJECEIAES
Optimized link state routing (OLSR) is a routing protocol that has a small delay, low traffic control, support the application of denser networks, and adopts the concept of multipoint relays (MPR). The problem of OLSR is routing table updating which continually causes excessive packet delivery, and energy consumption becomes increased. This article proposes the improvement of OLSR performance using the min-max algorithm based on the quality of service (QoS) with considering the density of the node. The Min-max algorithm works in selecting MPR nodes based on the largest signal range. The QoS parameters analyzed with a different number of nodes are packet delivery ratio (PDR), throughput, delay, energy consumption, and topology control (TC). Simulation result of network simulator version 2 (NS-2) shows that OLSR performance using the min-max algorithm can increase PDR of 91.17%, packet loss of 60.77% and reduce topology control packet of 8.07%, energy consumption of 16.82% compared with standard OLSR.
Performance comparison of mobile ad hoc network routing protocolsIJCNCJournal
Mobile Ad-hoc Network (MANET) is an infrastructure less and decentralized network which need a robust
dynamic routing protocol. Many routing protocols for such networks have been proposed so far to find
optimized routes from source to the destination and prominent among them are Dynamic Source Routing
(DSR), Ad-hoc On Demand Distance Vector (AODV), and Destination-Sequenced Distance Vector (DSDV)
routing protocols. The performance comparison of these protocols should be considered as the primary
step towards the invention of a new routing protocol. This paper presents a performance comparison of
proactive and reactive routing protocols DSDV, AODV and DSR based on QoS metrics (packet delivery
ratio, average end-to-end delay, throughput, jitter), normalized routing overhead and normalized MAC
overhead by using the NS-2 simulator. The performance comparison is conducted by varying mobility
speed, number of nodes and data rate. The comparison results show that AODV performs optimally well
not the best among all the studied protocols.
Novel Position Estimation using Differential Timing Information for Asynchron...IJCNCJournal
Positioning techniques have been a common objective since the early development of wireless networks. However, current positioning methods in cellular networks, for instance, are still primarily focused on the use of the Global Navigation Satellite System (GNSS), which has several limitations, like high power drainage and failure in indoor scenarios. This study introduces a novel approach employing standard LTE signaling in order to provide high accuracy positioning estimation. The proposed technique is designed in analogy to the human sound localization system, eliminating the need of having information from three spatially diverse Base Stations (BSs). This is inspired by the perfect human 3D sound localization with two ears. A field study is carried out in a dense urban city to verify the accuracy of the proposed technique, with more than 20 thousand measurement samples collected. The achieved positioning accuracy is meeting the latest Federal Communications Commission (FCC) requirements in the planner dimension.
Improving energy efficiency in manet’s for healthcare environmentsijmnct
Now a day ad hoc mobile networks (MANETs) have lots of routing protocols, but no one can meet

give better performance in location or global networks. Today modern and innovative applications for
health care environments based on a wireless network are being developed in the commercial sectors. The
emerging wireless networks are rapidly becoming a fundamental part of every single field of life. Our
proposed DEERP framework gives a better performance as compared to other routing protocol.

Bayesian Estimation of Above-Average Performance in Tertiary Institutions: A ...IOSR Journals
Bayesian approach for parameter estimation has the capacity to yield more precise estimates than methods based on sampling theory. There are several common Bayesian models; in this study we applied Empirical Bayes (EB) model called Beta-binomial model. The study is motivated by the need to beam searchlight on universities, faculties or fields of study with graduates who may not be eligible for further educational pursuits. This study provides means of assessment or a basis of evaluation of students’ performances among faculties or fields of study and overall performance of a university. This study uses Bayesian methods of inference to estimate the proportion of above-average performance of graduates from the various faculties in University of Lagos. The model adopted generated results which are of smaller variances compared with variances of sample Proportions, showing that the posterior proportions generated are more efficient estimators. This is further evidenced in narrow widths of the computed confidence intervals. The overall result shows that the proportion of above-average performance of graduates of University of Lagos, who are eligible for further educational pursuits (i.e. higher degrees), is approximately 72% of the university graduates
Energy Efficient Multipath Routing For Mobile Ad Hoc NetworksZac Darcy
Energy consumption is a significant issue in ad hoc networks since mobile nodes are battery powered. In
order to prolong the lifetime of ad hoc networks, it is the most critical issue to minimize the energy
consumption of nodes. In this paper, we propose an energy efficient multipath routing protocol for
choosing energy efficient path. This system also considers transmission power of nodes and residual energy
as energy metrics in order to maximize the network lifetime and to reduce energy consumption of mobile
nodes. The objective of our proposed system is to find an optimal route based on two energy metrics while
choosing a route to transfer data packets. This system is implemented by using NS-2.34. Simulation results
show that the proposed routing protocol with transmission power and residual energy control mode can
extend the life-span of network and can achieve higher performance when compared to traditional ad-hoc
on-demand multipath distance vector (AOMDV) routing protocol.

Wireless Sensor Networks (WSNs)have sensor nodes that sense and extract information from surrounding environment, processing information locally then transmit it to sink wirelessly. Multimedia data is larger in volume than scalar data, thus transmitting multimedia data via Wireless Multimedia Sensor Networks (WMSNs) requires stick constraints on quality of services in terms of energy, throughput and end to end delay.Multipath routing is to discover multipath during route discovery from source to sink. Discover multipath and sending data via these different paths improve the bandwidth and decrease the end to end delay. This paper introduces an Energy Location Aware Routing Protocol (ELARP) which is reactive multipath routing protocol establishing three paths with awareness of node’s residual energy and distance. ELARP has experimented with NS2 simulator. The simulation results show that ELARP enhances QoS for multimedia data in terms of end to end delay and packet delivery ratio.
The present paper describes a novel Raspberry Pi and Arduino UNO architecture used as a meteorological station. One of the advantages of the proposed architecture is the huge quantity of sensors developed for its usage; practically one can find them for any application, and weather sensing is not an exception. The principle followed is to configure Raspberry as a collector for measures obtained from Arduino, transmitting occurs via USB; meanwhile, Raspberry broadcasts them via a web page. For such activity is possible thanks to Raspbian, a Linux-based operating system. It has a lot of libraries and resources available, among them Apache Web Server, that gives the possibility to host a web-page. On it, the user can observe temperature, humidity, solar radiance, and wind speed and direction. Information on the web-page is refreshed each five minute; however, measurements arrive at Raspberry every ten seconds. This low refreshment rate was determined because weather variables normally do not abruptly change. As an additional feature, system stores all information on the log file, this gives the possibility for future analysis and processing.

Quality of Service Routing in Mobile Ad Hoc Networks Using Location and Energ...ijwmn
Mobile Ad hoc Networks are highly dynamic networks. Quality of Service (QoS) routing in such networks is usually limited by the network breakage due to either node mobility or energy depletion of the mobile nodes. Also, to fulfill certain quality parameters, presence of multiple node-disjoint paths becomes essential. Such paths aid in the optimal traffic distribution and reliability in case of path breakages. Thus, to cater such problem, we present a node-disjoint multipath protocol. The metric used to select the paths takes into account the stability of the nodes and the corresponding links. The proposed technique is also illustrated with an example.
Performance evaluation of MANET routing protocols based on QoS and energy p...IJECEIAES
Routing selection and supporting Quality of Service (QoS) are fundamental problems in Mobile Ad Hoc Network (MANET). Many different protocols have been proposed in the literature and some performance simulations are made to address this challenging task. This paper discusses the performance evaluation and comparison of two typical routing protocols; Ad Hoc On-Demand Distance Vector (AODV) and Destination-Sequenced DistanceVector (DSDV) based on measuring the power consumption in network with varing of the QoS parameters. In this paper, we have studied and analyzed the impact of variations in QoS parameter combined with the choice of routing protocol, on network performance. The network performance is measured in terms of average throughput, packet delivery ratio (PDR), average jitter and energy consumption. The simulations are carried out in NS-3. The simulation results show that DSDV and AODV routing protocols are less energy efficient. The main aim of this paper is to highlight the directions for the future design of routing protocol which would be better than the existing ones in terms of energy utilization and delivery ratio.

Simulation based comparison of routing protocols in wireless multihop ad hoc ...IJECEIAES
Routing protocols are responsible for providing reliable communication between the source and destination nodes. The performance of these protocols in the ad hoc network family is influenced by several factors such as mobility model, traffic load, transmission range, and the number of mobile nodes which represents a great issue. Several simulation studies have explored routing protocol with performance parameters, but few relate to various protocols concerning routing and quality of service (QoS) metrics. This paper presents a simulation-based comparison of proactive, reactive, and multipath routing protocols in mobile adhoc networks (MANETs). Specifically, the performance of AODV, DSDV, and AOMDV protocols are evaluated and analyzed in the presence of varying the number of mobile nodes, pause time, and traffic connection numbers. Moreover, Routing and QoS performance metrics such as normalized routing load, routing packet, packet delivery ratio, packet drop, end-to-end delay, and throughput are measured to conduct a performance comparison between three routing protocols. Simulation results indicate that AODV outperforms the DSDV and AOMDV protocols in most of the metrics. AOMDV is better than DSDV in terms of end-to-end delay. DSDV provides lower throughput performance results. Network topology parameters have a slight impact on AODV performance.

Bandwidth aware on demand multipath routing in manetsijwmn
Mobile Ad-hoc Networks (MANETs) are self configuring, decentralized and dynamic nature wireless
networks which have no infrastructure. These offer a number of advantages, however the demand of high
traffic flows in MANETs increases rapidly. For these demands, limited bandwidth of wireless network is the
important parameter that restrains the development of real time multimedia applications. In this work, we
propose a solution to utilize available bandwidth of the channel for on demand multiple disjoint paths. The
approximate bandwidth of a node is used to find the available bandwidth of the path. The source chooses
the primary route for data forwarding on the basis of path bandwidth. The simulation results show that the
proposed solution reduces the frequency of broadcast and performs well in improving the end to end
throughput, packet delivery ratio, and the end to end delay.
Design and implementation of new routingIJCNCJournal
Energy consumption is a key element in the Wireless Sensor Networks (WSNs) design. Indeed, sensor nodes are really constrained by energy supply. Hence, how to improve the network lifetime is a crucial and challenging task. Several techniques are available at different levels of the OSI model to maximize the WSN lifetime and especially at the network layer which uses routing strategies to maintain the routes in the network and guarantee reliable communication. In this paper we intend to propose a new protocol called
Combined Energy and Distance Metrics Dynamic Routing Protocol (CEDM-DR). Our new approach considers not only the distance between wireless sensors but also the energy of node acting as a router in order to find the optimal path and achieve a dynamic and adaptive routing.
The performance metrics exploited for the evaluation of our protocol are average energy consumed, network lifetime and packets lost. By comparing our proposed routing strategy to protocol widely used in WSN namely Ad hoc On demand Distance Vector(AODV), simulation results show that CEDM-DR strategy might effectively balance the sensor power consumption and permits accordingly to enhance the network
lifetime. As well, this new protocol yields a noticeable energy saving compared to its counterpart.
Link Stability and Energy Aware routing Protocol for Mobile Adhoc NetworkIOSR Journals
Abstract: MOBILE ad hoc networks (MANETs) have more popularity among mobile network devices and
wireless communication technologies. A MANET is multihop mobile wireless network that have neither a fixed
infrastructure nor a central server. Every node in a MANET will act as a router, and also communicates with
each other. The mobility constraints in mobile nodes will lead to problems in link stability. Energy saving, path
duration and stability will be two major efforts and to satisfy them can be difficult task. A self node which is
present in the network may also consume little energy during the transmission. This proposed approach tries to
account for link stability and for minimum drain rate energy consumption. In order to verify the correctness of
the proposed solution a objective optimization formulation has been designed and a novel routing protocol
called Link-Stability and Energy aware Routing protocols is proposed. This novel routing scheme has been
compared with other two protocols: PERRA and GPSR. The protocol performance has been evaluated in terms
of Data Packet Delivery Ratio, Normalized Control Overhead, Link duration, Nodes lifetime, and Average
energy consumption.

High mobility of mobile nodes is one of the major reasons for link failures in mobile ad hoc network (MANET). The present paper aims at proposing modification of well known Ad hoc On demand Distance Vector (AODV) routing protocol for MANET seeking stable route for data transmission and incorporating link break avoidance scheme for such networks. The performance of the proposed routing protocol, named as Route Stability based Ad hoc On demand Distance Vector (RSAODV), is evaluated considering some major performance metrics which include average route life time, throughput, packet delivery fraction, normalized routing load and end–to-end delay. The study is based on simulation runs adopting CBR traffic pattern taking care of node failure scenarios. The performance of RAODV is compared with AODV routing protocol. The simulation runs exhibit significant increase in average route life time, packet delivery fraction and throughput for RSAODV, on the other hand, the normalized routing load and end–to-end delay are reduced for this routing protocol as compared to AODV routing protocol.
A Performance Comparison of Routing Protocols for Ad Hoc NetworksIJERA Editor
Mobile Ad hoc Network (MANET) is a collection of mobile nodes in which the wireless links are frequently broken down due to mobility and dynamic infrastructure. Routing is a significant issue and challenge in ad hoc networks. Many routing protocols have been proposed like OLSR, AODV so far to improve the routing performance and reliability. In this paper, we describe the Optimized Link State Routing Protocol (OLSR) and the Ad hoc On-Demand Distance Vector (AODV). We evaluate their performance through exhaustive simulations using the Network Simulator 2 (ns2) by varying conditions (node mobility, network density).
A scalable and power efficient solution for routing in mobile ad hoc network ...ijmnct
Mobile Ad Hoc Network (MANET) is a very dynamic and infrastructure-less ad hoc network. The actual
network size depends on the application and the protocols developed for the routing for this kind of
networks should be scalable. MANET is a resource limited network and therefore the developed routing
algorithm for packet transmission should be power and bandwidth efficient. These kinds of dynamic
networks should operate with minimal management overhead. The management functionality of the
network increases with number of nodes and reduces the performance of the network. Here, in this paper,
we have designed all identical nodes in the cluster except the cluster head and this criterion reduces the
management burden on the network. Graph theoretic routing algorithm is used to develop route for packet
transmission by using the minimum resources. In this paper, we developed routing algorithm for cluster
based MANET and finds a path from source to destination using minimum cumulative degree path. Our
simulation results show that this routing algorithm provide efficient routing path with the increasing
number of nodes and uses multi-hop connectivity for intra-cluster to utilize minimum power for packet
transmission irrespective of number of nodes in the network.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Abstract : Energy is an important issue in MANET (Mobile Ad hoc Network). Nodes in network are working in
presence of limited energy. So, energy efficient routing is needed for reducing energy consumption. Energy
efficient routing schemes can greatly reduce energy consumption and extends the lifetime of the networks.
Multipath routing protocol (AOMDV) having more than one path, if the first one is break then second provides
the proper packet delivery, this causes reduced node energy consumption and the topology of MANETs always
changes, due to the high mobility of nodes. This makes it more difficult to find the routes that message packets
use when they are routed. The location based routing provides the location information of the destination to
route a packet toward. This paper provides comparison and study on reduced energy consumption by using
multipath protocol and performance which is evaluated by performance metrics in case of AOMDV and energy
based AOMDV. Now here DREAM protocol is used with AOMDV to finding location of mobile nodes but not
with energy but here measures their performance with both multipath protocols.
Keywords – AOMDV, Dream, Energy, MANET, Multipath
I. INTRODUCTION
A mobile ad hoc network (MANET) is a dynamic distributed system of mobile formed by means of
multi-hop wireless communication without the use of any existing network infrastructure. MANET routing
protocols can be classified into two classes. Proactive protocols, they requires the nodes to periodically
exchange the table information to update the pre-determine routes between any pair of source destination nodes.
Reactive protocols can establish routes only when they require. MANET routing protocols can be classified on
the bases of the methods of delivery of data packets from source to destination. Single Path routing protocols
learn routes and select a single best route to each destination. These protocols are incapable of load balancing
traffic. Multi-path routing protocols learn routes and can select more than one path to a destination. These
protocols are better for performing load balancing. This paper provides the comparison between results about
Multipath routing in AOMDV [13], AOMDV with location and Energy with AOMDV.
II. OVERVIEW OF SELECTED ROUTING PROTOCOLS
2.1. AD-HOC ON-DEMAND MULTI PATH DISTANCE VECTOR ROUTING (AOMDV)
One of the most commonly used AOMDV [1] is a multipath routing protocol provides loop-free
extension to another multipath routing protocol AODV [12]. It ensures about disjoint alternate paths at every
node, so that it can achieves path disjointness without using source routing. AOMDV with a route tables contain
a list of paths for each destination, to support multipath routing. All the paths have the same destination
sequence number to a destination. All the routes with the old sequence number are removed, once a rout
advertisement with higher sequence number is received. Two additional fields, hop count and last hop, are
stored in the route table entry to help address respectively the problems of loop freedom and path disjointness.
The loop freedom guarantee from AODV is no longer required here, because the multipath routing protocol
implement multipath discovery. AOMDV having two table fields hop count field and last hop field, in which
hop count field initialized once at the time of the first advertisement for that sequence number and contains
length of the longest path for a specific destination sequence number. That’s why hop count field remain
unchanged till a path for a higher destination sequence number is received. To ensure disjointness of that path in
the route table, a node discards a path advertisement that has either a common last hop or a common next hop as
already stored in the route table.
2.2. ENERGY WITH AOMDV OR ENERGY EFFICIENT AOMDV (AOMDV WITH ENERGY)
Reason behind the enhancement of AOMDV to AOMDV with energy [2], is to discover energy

descending order of nodal residual energy select all the routes. After this selection, a new route with maximum
residual energy is selected to forward rest of the data packets. These results in the improvement of the individual
node’s battery power consumption and enhance the entire network lifetime. Following steps involves in it:
2.2.1. Calculation of residual energy of each node for the route discovery process.
2.2.2. Calculation of the path with minimum nodal residual energy.
2.2.3. Selection of all the routes on the basis of descending value of nodal residual energy
2.2.4. Finally select the path with maximal nodal residual energy to forward the data packets.
2.3. LOCATION WITH AOMDV (DREAM)
DREAM [3] is a location-based routing protocol work for Ad-hoc networks. It stands for Distance
Routing Effect Algorithm for Mobility. Here in this comparison distance and mobility plays an important role,
so in our named as Distance Routing Effect Algorithm for Mobility (DREAM) protocol for ad hoc networks.
DREAM protocols have some desirable properties of providing bandwidth and energy efficiency. We can say
that with respect to existing protocols, in DREAM more bandwidth and energy (required for transmission in
each mobile node) can be used for the transmission of data messages. Most importantly:
2.3.1. The rate of control message generation is determined and optimized according to the mobility rate of each
node individually.
2.3.2. Due to the “distance effect” the number of hops (radius from the moving node) it will be allowed to
travel in the network before being discarded will only depend on the relative (geographic) distance between the
moving node and the location tables being updated.
DREAM protocol provide loop-free path, since each data message propagates away from its source in a specific
direction. DREAM protocol is also adaptive to mobility, since the frequency with which the location
information is disseminated depends on the mobility rate.
III. LITERATURE SURVEY
There are various previous work have been done in the field of Efficient energy in AOMDV, for the
improvement of Multipath routing with energy efficient techniques.
The researchers evaluates the performance of different AD-HOC routing protocols [2 ]such as DSDV,
AODV, TORA, DSR and AOMDV in terms of energy efficiency and it also suggests a new routing algorithm
that modifies AOMDV and also provides better performance compared to all the above protocols.
Pariza Kamboj and Ashok.K.Sharma,[4] research on the concept of local connectivity technique and
preventive route reconfiguration on the basis of the current status of the nodes are being proposed that attempts
to improve the performance and reliability in terms of reduced overhead, power and bandwidth requirement.
These techniques also ensure good reduction in latency in case of link breakages and prevention of the network
from splitting. The Energy Efficient Routing Multicast Protocol for MANET with Minimum Control Overhead
is compared with other shared tree multicast protocol i.e. MAODV. Comparison was made on various
parameters like Energy Consumption, Packet Delivery Ratio, Delay, and Throughput.
Azizol Abdullah et.al [6] produce the result of simulation done in identifying suitable ad hoc routing
protocol which can be used for the target mobile grid application. Here is a simulation, showing comparison
between three ad hoc routing protocols named as DSDV, DSR and AODV. This research mainly targets on the
performance comparison based on packet delivery fraction and normalized routing load. According to
researchers in future, extensive complex simulations could be carried out in gain a more in-depth performance
analysis of the ad hoc routing protocols.
Shwaita Kodesia et.al, proposed a mobile ad hoc network (MANET) [7] consists of autonomous
mobile nodes, each of the mobile nodes communicates directly with the nodes within its wireless range as well
indirectly connected with other nodes in a network. An efficient routing protocol is required to discover routes
between mobile nodes, in order to facilitate secure and reliable communication within a MANET. Due to the
many advantages and different application areas of MANET, this field is rapidly growing. Security and energy
efficiency are some challenges faced in MANETs, especially in designing a routing protocol. Here this is
surveyed a number of energy efficient routing protocols and secure routing protocols. Here the study says, these
protocols have different strengths and drawbacks.
Here the author Yun Ge et.al proposed a node-disjoint multipath routing protocol GMR [8] with the
group mobility model. This protocol adopts two different approaches of routing intra-group routing and inter-
group routing to adapt in two situations: within a group and among groups. Intra-group routing technique uses a
proactive method. And Intergroup routing technique uses a reactive method with the zoning method, which uses

dynamic topologies, and limits the region of broadcasting RREQ packets. The GMR protocol, provide group
mobility model with good scalability in large and dense MANETs.
Farukh Mahmudur Rahman, Mark A Gregory, proposes a new MANET routing algorithm [9] showing
quadrant based opportunistic routing, an intelligent energy matrix and energy status request messages with
packet receipt acknowledgement notification. This algorithm uses an intelligent energy matrix to creates a look
up table with the key characteristics: reputation value, residual battery level and energy consumption. This
algorithm also balances the traffic uniformly across four intermediate nodes in any desired quadrant. The
simulation shown here demonstrates the inclusion of the energy matrix and quadrant based routing, the number
of broadcast messages decreases, reducing data flooding, providing improved channel efficiency and improves
bandwidth utilization. To provide improved route stability, load balancing also increases the lifetime of
intermediate nodes.
Here, Hua Chen, Hui Xu et.al compare the performance of various protocols for ad hoc networks [10].
Multipath routing is based on fresnel zone routing (FZR), and Energy aware Node Disjoint Multipath Routing
(ENDMR) protocol. Simulations result show that, with the proposed network coding in ad hoc network
multipath routing protocol (NC-MR), packet delivery ratio, network lifetime and packet loss could be improved
in some of the cases.
Pariza Kamboj et.al constructs a shared bi-directional multicast tree [11] for its routing operations
rather than a mesh, which helps in achieving more efficient multicast delivery. This shows the concept of small
overlapped zones around each node for proactive topology maintenance within the zone. This algorithm
implements a protocol which depends on the location information obtained using a distributed location service,
which reduces shared multicast tree maintenance and overheads for route searching. This research provides a
new technique of local connectivity management that attempts to improve the performance and reliability.

4.3. RESULTS
In this section we present a set of simulation experiments to evaluate this protocol by comparing with
the original energy based AOMDV routing protocol. Results are obtained after doing simulation of both
previous and proposed scheme. Here we also include the performance of DREAM protocol.
4.3.1 PACKET LOSS ANALYSIS
This graph represents the packet loss analysis clearly show in location based routing (packetLo_lost.tr)
the packet loss is minimum as compare to normal AOMDV(packet_aomdv_lost.tr) and energy based
AOMDV(Epacket_lost.tr). But here the main observation in between AOMDV, energy based AOMDV and
location based AOMDV routing protocol. Here normal multipath routing has loss maximum number of packets.
In the absence of energy factor the normal routing has been done as according to multipath routing protocol but
after applying energy factor that always first calculate remaining energy of nodes then routing will done on the
basis of shortest path and hop count then packet loss is minimum in energy based AOMDV.
Fig.1 Packet loss analysis
4.3.2. PACKET DELIVERY FRACTION ANALYSIS(PDF)
Packet delivery fraction is the one of the important performance parameter this represents the packets
percentage successfully delivered to destination. Here the packet percentage in case of location based routing is
maximum because nodes are aware about the location of destination and due to the presence of multipath
routing protocol alternative route is always present then definitely PDF is more as compare to AOMDV and
energy based AOMDV.

Fig .2 Packet Delivery Fraction analysis
4.3.3. ROUTING LOAD ANALYSIS
In routing load analysis we observe that in energy based AOMDV protocol the routing load is
maximum it means that here links are break rapidly by that again connection request packets or control packets
are generated by sender then routing load increases and route disjoint path are also not able to provide strong
connection between sender and receiver but in normal multipath routing in the absence of energy factor routing
load is minimum because one link is break then second one is present to providing proper data delivery. Now
third case in DREAM protocol nodes are also forwarding data on the basis of location means senders are aware
about the position of destination with multiple routes (because of AOMDV) then the routing load in location
based routing is minimum as compare to all.
Fig. 3 Routing load analysis
V. CONCLUSIONS
In our simulations, we conduct the control overhead and the packet delivery rate with random mobility
speeds. Simulation results show that the proposed location based multipath (AOMDV) can reduce the control
overhead and increase the route lifetime than AOMDV. Only the forwarding neighboring nodes are involved in
routing while the non-forwarding nodes are switched to idle state. This ensures reduction in energy consumption
in the network. The results of DREAM location based protocol are very effective as compare to normal
AOMDV routing and energy based AOMDV routing. Routing overhead and packet delivery fraction are shows

excellent results with minimum packet loss. in location based multipath PDF are about 95% as compare
AOMDV of about 92% and AOMDV with energy is about 90% with minimum routing overhead.
In future we also measure the performance of DREAM protocol with energy factor and compare the
results with normal AOMDV location based routing. If the performance of energy based multipath routing
protocol is better than existing three then definitely it reduces energy consumption and enhance network life
time.
