A PROPOSAL FOR IMPROVE THE LIFETIME OF WIRELESS SENSOR NETWORKIJCNCJournal
The document proposes a new routing protocol for wireless sensor networks that aims to improve network lifetime. The protocol is based on LEACH, an existing energy-efficient clustering protocol, but improves on it by electing cluster heads based on both remaining node energy and distance to the base station. Simulation results show the proposed protocol extends network lifetime by up to 75% compared to LEACH alone by distributing energy usage more evenly across nodes.
Shortest path algorithm for data transmission in wireless ad hoc sensor networksijasuc
Wireless sensor networks determine probable in military, environments, health and commercial

network holds importance for such applications. Various constraints such as limited computation, storage
and power makes the process of transferring of information routing interesting and has opened new arenas
for researchers. The fundamental problem in sensor networks states the significance and routing of
information through a real path as path length decides some basic performance parameters for sensor
networks. This paper strongly focuses on a shortest path algorithm for wireless adhoc networks. The
simulations are performed on NS2 and the results obtained discuss the role of transferring of information
through a shortest path.
One of Machine Type Communication (MTC) applications is Wireless Sensor Network

autonomously. Sensor nodes in WSN, communicate over short distance via a wireless medium
and collaborate to accomplish a common task, such as enviroment monitoring, military
surveillance and industrial process control. The constraining aspect of WSN usage is the
limited power of each sensor node, so energy efficiency becomes an important issue in WSN.
Routing is a function in WSN, which consumes a substantial amount of energy. One of the
routing protocols that can increase the energy efficiency of WSN is Low Energy Adaptive

Base Station (BS) as sink node in WSN. HAP is designed at altitudes of 17, 20 and 22 km. Then
WSN over HAP using the LEACH routing protocol evaluated its performance. Performance
indicators that we evaluated are engergy consumption, number of dead nodes and total average
packets which is sent to HAP. From a series of simulations conducted, the results obtained that
the higher the laying of HAP, then the coverage area will be greater. So that the energy
consumption will be smaller, the number of dead node less and the avarage of total packet

WSN can be classified as static and mobile WSN. In static routing protocol, energy consumption is not uniformly distributed. To avoid this problem, wireless sensor network with mobile sink can be used, where mobile sink gathers data from other nodes using 1-hop communication.

Wireless Sensor Network (WSN) is a collection of small
sensor nodes in a geo-graphically distributed area to keep track
of physical or environmental conditions. If each node in the
network transmits the sensed data to the Base Station (BS), the
energy consumption is very high which directly affects the
network lifetime. By using clustering techniques, network
lifetime can be prolonged by making Cluster Head (CH) to
communicate with BS on behalf of other cluster members. We
have proposed a Mobile Sink (MS) scheme where the sink node
has more energy and resources compared to other sensor nodes.
The sink node moves near the clusters and gathers the sensed
data from the CH. Clustering is done and CHs are selected based
on the Residual Energy (RE) parameter. Simulation results and
analysis show that there is an improvement in throughput, delay,
packet delivery ratio with reduction in energy consumption
compared to schemes that use static sink or BS, where all the
CHs communicate the gathered data from the clusters members
to the static sink node. Thus mobile sink scheme increases the
network lifetime by reducing energy consumption.

The document proposes a new clustering protocol called DEEAC for wireless sensor networks. DEEAC is adaptive based on the data reporting rates and residual energy levels of nodes. It aims to distribute energy consumption more evenly across the network by selecting cluster heads that have high residual energy and are located in "hot regions" with high data generation rates. This is intended to prolong the lifetime of sensor networks compared to the original LEACH protocol.
The document proposes an energy saving multipath routing protocol (ESMRP) for wireless sensor networks. ESMRP uses a load balancing algorithm to discover multiple node-disjoint paths from sensor nodes to a sink node based on calculated node strengths. It then transmits data along the paths either by single path load balancing or splitting messages across multiple paths with error correction. Simulation results show that ESMRP consumes less energy and has higher delivery ratios than previous protocols.

The applications require coverage of the whole monitored area for long periods of time. Clustering is a
way to reduce communications, minimize energy consumption and organize messages among the cluster
head and their members. The message exchange of communication and data transmission between the
different sensor nodes must be minimized to keep and extended the lifetime of the network because of
limited energy resources of the sensors. In this paper, we take into consideration the problem isolated
nodes that are away from the cluster head (CH) and by consequence or CH is not within the reach from
these nodes. To solve this problem, we propose O-LEACH (Orphan Low Energy Adaptive Clustering
Hierarchy) a routing protocol that takes into account the orphan nodes. Indeed, a cluster member will be
able to play the role of a gateway which allows the joining of orphan nodes. Our contribution is to election
a cluster head that has enough energy for a better now to coordinate with these member nodes and
maintain the full coverage for applications which requires of useful data for the entire area to be covered.
The simulation results show that O-LEACH performs better than LEACH in terms of connectivity rate,
energy, scalability and coverage.
THRESHOLD SENSITIVE HETEROGENOUS ROUTING PROTOCOL FOR BETTER ENERGY UTILIZATI...ijassn
Advancements in WSN have led to the wide applicability of sensor network in various fields. WSNs basic classification is Reactive and Proactive network. Reactive networks responds to the very immediate changes in its environment in required parameters of interest, as opposed to the Proactive network, due to continuous sensing nature of WSN. To make it more efficient and improved in terms of Energy in network’s
lifetime, we need to reduce the energy expense in the network model, which is one of the most significant issues in wireless sensor networks (WSNs) [1, 2]. In this paper, we proposed an efficient version of TSEP Protocol, which prolongs the networks lifetime by efficient utilization of sensor energy, as we have simulated. We evaluated the performance of our protocol and compared the results with the TSEP. And from the results of simulation, it can be concluded easily that our proposed efficient routing protocol performs better in terms of network lifetime and stability period
I-Min: An Intelligent Fermat Point Based Energy Efficient Geographic Packet F...graphhoc
Energy consumption and delay incurred in packet delivery are the two important metrics for measuring the performance of geographic routing protocols for Wireless Adhoc and Sensor Networks (WASN). A protocol capable of ensuring both lesser energy consumption and experiencing lesser delay in packet delivery is thus suitable for networks which are delay sensitive and energy hungry at the same time. Thus a smart packet forwarding technique addressing both the issues is thus the one looked for by any geographic routing protocol. In the present paper we have proposed a Fermat point based forwarding technique which reduces the delay experienced during packet delivery as well as the energy consumed for transmission and reception of data packets.
Fuzzy Route Switching for Energy Preservation(FEP) in Ad Hoc NetworksA. Sufian
Nodes in ad hoc networks have limited battery power. Hence they require energy-efficient technique to improve average
network performance. Maintaining energy-efficiency in ad hoc networks is really challenging because highest energyefficiency
is achieved if all the nodes are always switched off and energy-efficiency will be minimum if all the nodes are
fully operational i.e. always turned-on. Energy preservation requires redirection of data packets through some other routes
having good performance. This improves data packet delivery ratio and number of alive nodes decreasing cost of messages.
This document analyzes and compares the performance of five wireless sensor network clustering protocols: LEACH, EEHC, the protocol by Indranil et al., HEED, and DWEHC. It discusses the operation and key aspects of each protocol, defines quantitative and qualitative performance metrics for analyzing clustering protocols, and presents the results of simulations comparing the protocols based on metrics like total residual energy, number of dead nodes, aggregated data sent to the base station, and overhead. The analysis found that DWEHC performed the best overall by efficiently distributing energy usage through multi-level clustering and minimizing direct communication between nodes and the base station.
Packet Loss and Overlay Size Aware Broadcast in the Kademlia P2P SystemIDES Editor
Kademlia is a structured peer-to-peer (P2P)
application level network, which implements a distributed
hash table (DHT). Its key-value storage and lookup service is
made efficient and reliable by its well-designed binary tree
topology and dense mesh of connections between participant
nodes. While it can carry out data storage and retrieval in
logarithmic time if the key assigned to the value in question
is precisely known, no complex queries of any kind are
supported. In this article a broadcast algorithm for the
Kademlia network is presented, which can be used to
implement such queries. The replication scheme utilized is
compatible with the lookup algorithm of Kademlia, and it
uses the same routing tables. The reliability (coverage) of the
algorithm is increased by assigning the responsibility of
disseminating the broadcast message to many nodes at the
same time. The article presents a model validated with
simulation as well. The model can be used by nodes at runtime
to calculate the required level of replication for any desired
level of coverage. This calculation can take node churn, packet
loss ratio and the size of the overlay into account.
Fuzzy-controlled Scheduling of Real Time Data Packets (FSRP) in Mobile Ad Hoc...A. Sufian
Abstract—In ad hoc networks, the data packets can be mainly classified into two categories – real time and
non-real time. Definitely the scheduling of real time data packets is going to be different from non-real time
ones. The deadline of delivery is a very important criterion to be met in case of real time packets. The other
requirements like velocity and energy concerns are enforced by the inherent dynamic nature of ad hoc
networks. Sometimes it becomes completely unnecessary to forward a real time data packet when the deadline
is impossible to meet or when the destination is on the verge of death. Also if the source nodes start sending
real time packets at a very high rate, then it will not only increase congestion in the network but also hamper
the forwarding of non real time packets since non real times have priority lesser than the real time packets.
The present algorithm FSRP is designed considering all these factors and the performance improvement it
produces is very significant compared to other state of the art scheduling protocols.

It proposes a new technique called RALEACH that decides a threshold value for cluster head election based on the ratio of current packet length to control packet length, as well as general and current state probabilities. Simulation results show that RALEACH improves network lifetime, data traffic sent, time until first node death, total rounds, and residual energy consumption compared to LEACH, ALEACH, and WALEACH routing protocols.
An Improved Energy Efficient Wireless Sensor Networks Through Clustering In C...Editor IJCATR
One of the major reason for performance degradation in Wireless sensor network is the overhead due to control packet and packet delivery degradation. Clustering in cross layer network operation is an efficient way manage control packet overhead and which ultimately improve the lifetime of a network. All these overheads are crucial in a scalable networks. But the clustering always suffer from the cluster head failure which need to be solved effectively in a large network. As the focus is to improve the average lifetime of sensor network the cluster head is selected based on the battery life of nodes. The cross-layer operation model optimize the overheads in multiple layer and ultimately the use of clustering will reduce the major overheads identified and their by the energy consumption and throughput of wireless sensor network is improved. The proposed model operates on two layers of network ie., Network Layer and Transport Layer and Clustering is applied in the network layer . The simulation result shows that the integration of two layers reduces the energy consumption and increases the throughput of the wireless sensor networks.
The document summarizes a research paper that proposes improvements to the LEACH (Low Energy Adaptive Clustering Hierarchy) routing protocol for wireless sensor networks. It begins by describing the basic LEACH protocol and some of its limitations, such as uneven energy consumption and long-distance transmissions from cluster heads to the base station. The proposed EE-LEACH modified protocol aims to make cluster head selection dependent on residual node energy and distance to other cluster heads, in order to balance energy usage and improve network lifetime. The protocol modifications and objectives are outlined, along with the simulation parameters that will be used to analyze energy efficiency improvements compared to the basic LEACH protocol.
Efficient and Optimal Routing Scheme for Wireless Sensor Networkspaperpublications3
Abstract: The Wireless Sensor Networks (WSNs) have emerged as a new category of networking systems with limited computing, communication, and storage resources. In many sensing applications source nodes deliver packets to sink nodes via multiple hops, leading to the problem on how to find routes that enable all packets to be delivered in required time frames, while simultaneously taking into account factors such as energy efficiency and load balancing. To solve this problem one data collection protocol is developed called EDAL, which stands for Energy-efficient Delay-aware Lifetime-balancing data collection. Methods used are centralized heuristic and ant colony gossiping to find best energy efficient path. Then integrate EDAL with compressive sensing to reduce the amount of traffic generated and to reduce delay in the network.

Prolong Lifetime Analysis and Efficient Utilization of Energy in Heterogeneou...IJTET Journal
Abstract - The clustering-based protocols are believed to be the best for heterogeneous wireless sensor networks (WSNs). The evaluation is based on two new clustering-based protocols, which are called single-hop energy-efficient clustering protocol (S-EECP) and multi-hop energy-efficient clustering protocol (M-EECP) [1]. In S-EECP, the cluster heads (CHs) are elected by a weighted probability [2] based on the ratio between average energy of the network and residual energy of each node. The nodes having more initial energy and residual energy will have more chances to be elected as CHs than nodes with low energy. In M-EECP, the election of CHs is same as S-EECP, but the elected CHs communicate the data packets to the base station via multi-hop communication approach. To analyze the network lifetime three types of sensor nodes equipped with different battery energy are assumed. By analyzing these parameters, M-EECP achieves load balance among the CHs better than the existing clustering protocols and gives prolong network lifetime. Here the simulation is based on ns-2 simulator.
MuMHR: Multi-path, Multi-hop Hierarchical RoutingM H
This document proposes a new routing protocol called MuMHR for wireless sensor networks. MuMHR aims to improve energy efficiency and robustness over LEACH in three ways: 1) By enabling nodes to select cluster heads based on the number of hops away to reduce transmission distances. 2) By using a back-off timer and multiple paths for transmissions to reduce setup overhead and add reliability. 3) By electing backup cluster heads to substitute when primary heads fail. The protocol operates in setup and data transfer phases, with the setup phase selecting cluster heads and forming clusters in an energy-efficient multi-hop manner.

This document discusses clustering techniques to analyze communication overhead in wireless sensor networks. It describes how clustering can help reduce energy consumption and traffic load by limiting redundant data transmission. The document compares the K-means and fuzzy clustering algorithms. The K-means algorithm partitions nodes into K clusters based on distance from cluster centers, while fuzzy clustering allows nodes to belong to multiple clusters. A simulation found that fuzzy clustering results in lower communication overhead than K-means as node velocity increases, helping to increase network lifetime.

The document summarizes a proposed spatial correlation-based medium access control protocol for wireless sensor networks that aims to improve energy efficiency. It discusses how sensor nodes are spatially distributed and correlated in detecting events. An iterative node selection algorithm is used to select a minimum set of representative sensor nodes based on a distortion constraint, in order to reduce redundant transmissions. The protocol uses vector quantization to calculate distances between nodes and a mobile element. It then evaluates the performance of using the DSR and AODV routing protocols with this spatial correlation-based MAC protocol in terms of energy consumption and packet drop ratio through simulations. The simulation results show that the protocol with AODV routing performs better than with DSR routing.

As the focus is to improve the average lifetime of sensor network the cluster head is selected based on the battery life of nodes. The cross-layer operation model optimize the overheads in multiple layer and ultimately the use of clustering will reduce the major overheads identified and their by the energy consumption and throughput of wireless sensor network is improved. The proposed model operates on two layers of network ie., Network Layer and Transport Layer and Clustering is applied in the network layer . The simulation result shows that the integration of two layers reduces the energy consumption and increases the throughput of the wireless sensor networks.
The document summarizes a research paper that proposes improvements to the LEACH (Low Energy Adaptive Clustering Hierarchy) routing protocol for wireless sensor networks. It begins by describing the basic LEACH protocol and some of its limitations, such as uneven energy consumption and long-distance transmissions from cluster heads to the base station. The proposed EE-LEACH modified protocol aims to make cluster head selection dependent on residual node energy and distance to other cluster heads, in order to balance energy usage and improve network lifetime. The protocol modifications and objectives are outlined, along with the simulation parameters that will be used to analyze energy efficiency improvements compared to the basic LEACH protocol.
Efficient and Optimal Routing Scheme for Wireless Sensor Networkspaperpublications3
Abstract: The Wireless Sensor Networks (WSNs) have emerged as a new category of networking systems with limited computing, communication, and storage resources. In many sensing applications source nodes deliver packets to sink nodes via multiple hops, leading to the problem on how to find routes that enable all packets to be delivered in required time frames, while simultaneously taking into account factors such as energy efficiency and load balancing. To solve this problem one data collection protocol is developed called EDAL, which stands for Energy-efficient Delay-aware Lifetime-balancing data collection. Methods used are centralized heuristic and ant colony gossiping to find best energy efficient path. Then integrate EDAL with compressive sensing to reduce the amount of traffic generated and to reduce delay in the network.

Prolong Lifetime Analysis and Efficient Utilization of Energy in Heterogeneou...IJTET Journal
Abstract - The clustering-based protocols are believed to be the best for heterogeneous wireless sensor networks (WSNs). The evaluation is based on two new clustering-based protocols, which are called single-hop energy-efficient clustering protocol (S-EECP) and multi-hop energy-efficient clustering protocol (M-EECP) [1]. In S-EECP, the cluster heads (CHs) are elected by a weighted probability [2] based on the ratio between average energy of the network and residual energy of each node. The nodes having more initial energy and residual energy will have more chances to be elected as CHs than nodes with low energy. In M-EECP, the election of CHs is same as S-EECP, but the elected CHs communicate the data packets to the base station via multi-hop communication approach. To analyze the network lifetime three types of sensor nodes equipped with different battery energy are assumed. By analyzing these parameters, M-EECP achieves load balance among the CHs better than the existing clustering protocols and gives prolong network lifetime. Here the simulation is based on ns-2 simulator.
MuMHR: Multi-path, Multi-hop Hierarchical RoutingM H
This document proposes a new routing protocol called MuMHR for wireless sensor networks. MuMHR aims to improve energy efficiency and robustness over LEACH in three ways: 1) By enabling nodes to select cluster heads based on the number of hops away to reduce transmission distances. 2) By using a back-off timer and multiple paths for transmissions to reduce setup overhead and add reliability. 3) By electing backup cluster heads to substitute when primary heads fail. The protocol operates in setup and data transfer phases, with the setup phase selecting cluster heads and forming clusters in an energy-efficient multi-hop manner.

It describes how clustering can help reduce energy consumption and traffic load by limiting redundant data transmission. The document compares the K-means and fuzzy clustering algorithms. The K-means algorithm partitions nodes into K clusters based on distance from cluster centers, while fuzzy clustering allows nodes to belong to multiple clusters. A simulation found that fuzzy clustering results in lower communication overhead than K-means as node velocity increases, helping to increase network lifetime.

The document summarizes a proposed spatial correlation-based medium access control protocol for wireless sensor networks that aims to improve energy efficiency. It discusses how sensor nodes are spatially distributed and correlated in detecting events. An iterative node selection algorithm is used to select a minimum set of representative sensor nodes based on a distortion constraint, in order to reduce redundant transmissions. The protocol uses vector quantization to calculate distances between nodes and a mobile element. It then evaluates the performance of using the DSR and AODV routing protocols with this spatial correlation-based MAC protocol in terms of energy consumption and packet drop ratio through simulations. The simulation results show that the protocol with AODV routing performs better than with DSR routing.

DYNAMIC RE-CLUSTERING LEACH-BASED (DR-LEACH) PROTOCOL FOR WIRELESS SENSOR NET...IJCNCJournal
A Wireless Sensor Network (WSN) contains a large number of sensor nodes equipped with limited energy supplies. In most applications, sensor nodes are deployed in a random fashion. Therefore, battery replacement or charging is considered not practical. As a result, routing protocols must be energy-efficient to prolong the network’s lifetime. In this paper, we propose a new Dynamic Re-clustering LEACH-Based protocol (DR-LEACH) which aims to reduce the energy consumption and extending the network’s lifetime. The idea is to balance energy consumption of Cluster Heads (CHs) by generating clusters with almost equal number of nodes during each round of the network life time. To perform this, we first calculate the optimal number of CHs in each round, and based on that we calculate the optimal size of each cluster. Results show that the proposed protocol improves network lifetime and reduces overall energy consumption compared to LEACH and BCDCP protocols.
This document summarizes and compares various clustering protocols for wireless sensor networks. It discusses clustering parameters like number of clusters and node mobility. It also classifies clustering algorithms into two main categories: probabilistic (e.g. LEACH) and non-probabilistic (e.g. weight-based and graph-based). Popular probabilistic protocols like LEACH, EEHC and HEED are described. Non-probabilistic protocols discussed include those based on node proximity, weights, and biologically inspired approaches. Overall, the document provides an overview of different clustering algorithm types and compares their advantages and disadvantages.
Minimum distance based routing protocol for lifetime improvement in wireless ...eSAT Journals
Abstract Balanced utilization of energy of wireless sensor nodes is a challenge while designing wireless sensor network (WSN). This energy of sensor node is a limited resource and measure for the lifespan of WSN. Communication process consumes most of the energy of sensor node hence; energy of sensor node becomes a major design issue for WSN. Clustering is preferred while designing routing protocols for WSN for its many to one traffic pattern. In our minimum distance based routing protocol for lifetime improvement in WSN (MDBRP) clusters are formed once in a lifetime and their heads are selected rotationally based on minimum communication distance between nodes and their next hop. MDBRP considers minimum energy consumption which aims to increase the overall lifespan of WSN. Keywords— clustering, dynamic clustering, routing protocol, static clustering, wireless sensor network.

Data gathering in wireless sensor networks using intermediate nodesIJCNCJournal
Energy consumption is an essential concern to Wireless Sensor Networks (WSNs).The major cause of the energy consumption in WSNs is due to the data aggregation. A data aggregation is a process of collecting data from sensor nodes and transmitting these data to the sink node or base station. An effective way to perform such a task is accomplished by using clustering. In clustering, nodes are grouped into clusters where a number of nodes, called cluster heads, are responsible for gathering data from other nodes, aggregate them and transmit them to the Base Station (BS).
In this paper we produce a new algorithm which focused on reducing the transmission bath between sensor nodes and cluster heads. A proper utilization and reserving of the available power resources is achieved with this technique compared to the well-known LEACH_C algorithm.
