Abstract-The two factors included for deployment of any Wireless Sensor Network, those factors are efficient energy and fault tolerance. An efficient solution for fault tolerance is the Multipath routing in WSNs. Genetic Algorithm is based on the meta-heuristic search technique. Base station (BS) already prepared routing schedule in its routing table, all the nodes share it with the entire network. In proposed algorithm various parameters are used for efficient fitness function such as distance between sender and receiver nodes, distance between BS to hop node and on the number of hop to send data from next hop node to the BS. Simulation and evaluation are tested with various performance metrics in the proposed algorithm.
Performance Analysis of Bfsk Multi-Hop Communication Systems Over K-μ Fading ...ijwmn
Multi-hop communication systems gained popularity in wireless communications; they can be used to
extend the coverage of the network and reduce the transmitted power. The transmission of data from the
source node to the destination node in multi-hop communications undergoes through intermediate relay
nodes. In this paper, we study the performance of multi-hop communication systems, in terms of average bit
error rate (BER) with Binary frequency shift keying assuming the κ-µ fading channel model. Due to the
difficulty in finding the probability density function (PDF) of the end-to-end signal to noise ratio (SNR) and
hence for the performance metrics, we use Gaussian Mixture (GM) approximation technique to
approximate the PDF of the end to end SNR assuming the κ-µ fading models as weighted sums of Gaussian
distributions. Numerical results are provided for the BER of binary frequency shift keying (BFSK) of
amplify and forward (AF) multi-hop communication systems assuming different values for the fading
parameters (, ) and for different number of hops. Numerical results are validated by comparing them
with simulation results.
Wireless Mesh Network rose as a promising innovation for providing quick and productive communication for which numerous algorithms have been proposed in networking infrastructure. For routing there are various performance parameters such as throughput, network congestion, resiliency, fairness, robustness, network jitter, delay, stability, optimality, simplicity, completeness etc. Robustness provides the capability to deal with all the failures that come across during the connection in the network to increase the network performance. In this paper we have studied and analyzed three algorithms namely on robustness parameter Resilient multicasting [2], Resilient Opportunistic Mesh Routing for Wireless Mesh Network (ROMER) [3], and Buffer Based Routing (BBR) [4], in Wireless Mesh Networks. Analysis through various parameters such as network congestion, network throughput and resiliency [5], shows network performance of BBR is better.

Energy efficiency is the most critical challenge in wireless sensor network. The transmission energy is the most consuming task in sensor nodes, specifically in large distances. Clustered routing techniques are efficient approaches used to lower the transmission energy and maximize the network’s lifetime. In this paper, a hybrid clustered routing approach is proposed for energy optimization in WSN. This approach is based on KMeans clustering algorithm and LEACH protocol. The simulation results using MATLAB tool have shown that the proposed hybrid approach outperforms LEACH protocol and optimizes the nodes energy and the network lifetime.

We refer to the problem of constructing broadcast trees with cost and delay constraints in the networks as a delay-constrained minimum spanning tree problem in directed networks. Hence it is necessary determining a spanning tree of minimal cost to connect the source node to all nodes subject to delay constraints on broadcast routing. In this paper, we proposed a genetic algorithm for solving broadcast routing by finding the low-cost broadcast tree with minimum cost and delay constraints. In this research we present a genetic algorithm to find the broadcast routing tree of a given network in terms of its links. The algorithm uses the connection matrix of the given network to find the spanning trees and considers the weights of the links to obtain the minimum spanning tree. Our proposed algorithm is able to find a better solution, fast convergence speed and high reliability. The scalability and the performance of the algorithm with increasing number of network nodes are also encouraging.
Maximizing network capacity and reliable transmission in mimo cooperative net...eSAT Journals
Abstract Network capacity is an important factor to measure the performance of a network. Cooperative networking is a phenomenon which helps network to have significant gains in terms of transmission reliability and network capacity. Cooperating networking has been applied to multi-hop ad hoc networks. However, the existing works have two limitations. They support only single antenna model and three node relay scheme. The reason behind this limitation due to lack of complete understands of optimal power allocation structure Multiple Input and Multiple Output (MIMO) cooperative networks. Recently Liu et al. studied structural properties with respect to MIMO cooperative networks in presence of node power constraints. Each power allocation at source follows corresponding MIMO structure so as to ensure optimal power allocation. They establish relationship between cooperative relay and pure relay to quantify performance gain. In this paper we did experiments on this concept. Our simulations reveal that the proposed system for cooperative network is able to achieve both transmission reliability and network capacity.

Abstract: Energy consumption is one of the constraints in Wireless Sensor Networks (WSNs). The routing protocols are the hot areas to address quality-of-service (QoS) related issues viz. Energy consumption, network lifetime, network scalability and packet overhead. In existing system a hybrid optimization based PEGASIS-DSR optimized routing protocol (PDORP) is presented which used cache and directional transmission concept of both proactive and reactive routing protocols. The performance of PDORP has been evaluated and the results indicated that it performs better in most significant parameters. The performance of the existing method is checked when it is evaluated and validated with the nodes which are highly dynamic in nature based on the application requirement. The current system finds the trusted nodes in the case of only static environment. To overcome the issue the proposed system is applied for dynamic WSN’s with the location frequently being changed. The PDORP-LC is applied with local caching (LC) to acquire the location information so that the path learning can be dynamic without depending on the fixed location. The proposed work is performing in dynamic environment with the dynamic derivation of trusted nodes.

Performance Analysis of Enhanced Opportunistic Minimum Cost Routingin Mobile ...IJERA Editor
Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network with
infrastructure less environment to establish a data transmission between nodes within the network. A routing
protocol is used to discover routes between nodes. In this paper, we study the three existing routing protocols
namely AODV, DSDV and DSR to analyze theirperformance based on set of parameters.AODV and DSR
deliver almost all the packets compared to DSDV. Hence we try to modify the AODVprotocol and use in the
cooperative transmission.
In this paper, we study the cooperative transmission at the network layer and cooperative diversity at the
physical layer as a joint optimization of the transmission power in a Mobile Ad-Hoc Network (MANET) with
static channel. However due to variable wireless channels static routing is suboptimal. Proposed protocol
proactively selects forwarding nodes that work cooperatively forwarding the packet towards the destination.
Cooperative transmission side diversity helps in reducing interference. Diversity can be achieved at the physical
layer by coordinating the multiple nodes. Nodes are equipped with Omni-directional antenna and take the
advantages of transmission side diversity to achieve energy saving, under the assumption that channel gains are
available at the transmitters.
The proposed Opportunistic Minimum Cost Cooperative Transmission Shortest Path (OMCTSP) algorithms
select the best optimum route with minimum cost in terms of energy, number of hops, available bandwidth, link
quality (SNR) and outage probability. As the network becomes larger, finding optimal routes becomes
computationally intractable as the complexity of the dynamic programming (DP) approach increases as o (22n)
where n is the number of nodes in the networks. Hence we develop two suboptimal algorithms have complexity
of o (n2) perform as same as optimal algorithm. Also developthe Opportunistic Cooperative Routing in MANET
(O_CORMAN), which is a network layer opportunistic routing scheme for mobile ad hoc networks. Nodes in
the network use the components proactive routing protocol, forwarder list update and local re-transmission. We
evaluate the performance using NS 2.32 simulator there is significant performance improvement with respect to
energy, throughput packet delivery, and delay compared with Modified AODV (OMCTSP).
Distributed Three Hop Routing Protocol for Enhancing Routing Process in WSNpaperpublications3
Abstract: For Hybrid wireless network there is need of efficient data routing protocol for improvement of network capability and scalability. By using Distributed Three Hop routing protocol (DTR), we improve capacity of Hybrid network and Reduce overhead. In early Two- Hop Transmission protocol is used for eliminate route maintenance and limited number of hop in routing for Hybrid Wireless Network but it only considers the node transmission within a single cell while DTR can Also deals with Inter-cell communication in real word. DTR is Top-quality from Other routing Protocol to analyses the hybrid wireless networks with the parametric quantity such as throughput, QoS, packet loss, overhead (due to traffic), channel quality, load balancing, routing delivery, scalability and power consumption. DTR also has a congestion control algorithm to avoid load congestion in base station in the case of unbalanced traffic distributions in networks. DTR makes significantly lower overhead by eliminating route monitoring and maintenance. To enhance the efficiency of routing protocol in wireless network Weight Based Data Assignment technique is used for data allocation in distributed routing protocol using the technique of least delay detection to maintain less data congestion in the network . for that DTR divides a message data stream into segments and transmits the segments in a distributed manner.

Performance Analysis of Distributed Spatial Multiplexing with Multi-hop Ampli...IJCSEA Journal
This paper describes a frame work investigating the performance of distributed spatial multiplexing (DSM) in cooperative multi-hop cellular networks. The cooperative communication in cellular networks gives us leverage to get the inherent advantages of its random relay locations and the direction of the data flow. However, traditional centralized relay selection needs considerable overhead and signaling. In our proposed work, threshold based relay selection is adopted based on the received signal strength (RSS) and Signal to Noise Ratio (SNR). The best relay chosen will transmit jointly with source using Amplify and forward (AF) protocol. The evaluation is performed with bit error rate (BER) and energy per bit for distributed spatial multiplexing scheme with multi-hop networking.
The maximization of a networks lifetime is an important part of research in the present scenario. In ad hoc network, the topology of network changes frequently due to the mobility of mobile nodes where the communication is possible without any network infrastructure. Mobile nodes have limited energy resources so that the energy efficient routing should be provided which increases the life time of the network. The existing routing mechanisms do not consider energy of nodes for data transmission. In this paper a novel approach is analyzed to improve the networks lifetime where the data transfer is based on the minimum hop count and residual energy of the mobile nodes. The analysis is carried out by using the network simulator and the simulation results shows that the proposed work provides an energy efficient routing in ad hoc networks.
Device Discovery Schemes for Energy-Efficient Cluster Head Rotation in D2DTELKOMNIKA JOURNAL
In this paper, novel device discovery approaches for the cluster head rotation, which is a state-ofthe-
art method for the Device-to-Device communication, are proposed. The device discovery is the
process to detect and to include new devices in the Device-to-Device communication. The proposed
device discovery is aimed to attain energy efficiency for the communication devices. We propose two
schemes for the device discovery: eNB-assisted and independent device discovery. Compared to previous
work, the proposed device discovery is utilizing the cluster head rotation method, to achieve better energy
efficiency. In this work, several simulations were performed and discussed for both schemes. In the first
simulation, the device energy consumption is examined. After that, the number of devices that get rejected
is studied. The device discovery processes in multi cluster head scenario, which is cluster head rotation,
are examined in this paper. The result of the simulation shows that eNB-assisted device discovery can
provide better energy efficiency. Also, the number of rejected devices of the eNB-assisted device
discovery is slightly lower than independent device discovery.
Energy saving in cooperative transmission using opportunistic protocol in MANETIOSR Journals
Abstract : In this thesis, we study the joint problems of cooperative link and diversity in A Mobile Ad-Hoc Network (MANET) with variable wireless channels. In MANET the wireless nodes are in group and infrastructure less in nature. The major problems faced by wireless communication in real time environment are that of interference and un-reliable communication links. Much research work has been done to overcome this by using various techniques. Cooperative communication and transmission side diversity in the network are the two of the techniques that help in reducing interference and communication link failures. We have also proposed a new technique to find the optimum route as a joint problem of the transmission power at the physical layer and the link selection at the network layer that incurs the minimum cost in terms of energy, no. of hops, available bandwidth and link quality (SNR), outage probability. Analytical results show that our cooperative transmission schemes (OMCTSP) achieves average energy saving of more than 80% than direct transmission.

IMPROVEMENTS IN ROUTING ALGORITHMS TO ENHANCE LIFETIME OF WIRELESS SENSOR NET...IJCNCJournal
Wireless sensor network (WSN) brings a new paradigm of real-time embedded systems with limited
computation, communication, memory, and energy resources that are being used fora huge range of
applications. Clustering in WSNs is an effective way to minimize the energy consumption of sensor nodes.
In this paper improvements in various parameters are compared for three different routing algorithms.
First, it is started with Low Energy Adaptive Cluster Hierarchy (LEACH)which is a famed clustering
mechanism that elects a CH based on the probability model. Then, work describes a Fuzzy logic system
initiated CH selection algorithm for LEACH. Then Artificial Bee Colony (ABC)which is an optimisation
protocol owes its inspiration to the exploration behaviour of honey bees. In this study ABC optimization
algorithm is proposed for fuzzy rule selection. Then, the results of the three routing algorithms are
compared with respect to various parameters
An Efficient Algorithm to Calculate The Connectivity of Hyper-Rings Distribut...ijitcs
The aim of this paper is develop a software module to test the connectivity of various odd-sized HRs and attempted to answer an open question whether the node connectivity of an odd-sized HR is equal to its degree. We attempted to answer this question by explicitly testing the node connectivity's of various oddsized HRs. In this paper, we also study the properties, constructions, and connectivity of hyper-rings. We usually use a graph to represent the architecture of an interconnection network, where nodes represent processors and edges represent communication links between pairs of processors. Although the number of edges in a hyper-ring is roughly twice that of a hypercube with the same number of nodes, the diameter and the connectivity of the hyper-ring are shorter and larger, respectively, than those of the corresponding hypercube. These properties are advantageous to hyper-ring as desirable interconnection networks. This paper discusses the reliability in hyper-ring. One of the major goals in network design is to find the best way to increase the system’s reliability. The reliability of a distributed system depends on the reliabilities of its communication links and computer elements

Performance Analysis of Distributed Spatial Multiplexing with Multi-hop Ampli...IJCSEA Journal
This paper describes a frame work investigating the performance of distributed spatial multiplexing (DSM) in cooperative multi-hop cellular networks. The cooperative communication in cellular networks gives us leverage to get the inherent advantages of its random relay locations and the direction of the data flow. However, traditional centralized relay selection needs considerable overhead and signaling. In our proposed work, threshold based relay selection is adopted based on the received signal strength (RSS) and Signal to Noise Ratio (SNR). The best relay chosen will transmit jointly with source using Amplify and forward (AF) protocol. The evaluation is performed with bit error rate (BER) and energy per bit for distributed spatial multiplexing scheme with multi-hop networking.
The maximization of a networks lifetime is an important part of research in the present scenario. In ad hoc network, the topology of network changes frequently due to the mobility of mobile nodes where the communication is possible without any network infrastructure. Mobile nodes have limited energy resources so that the energy efficient routing should be provided which increases the life time of the network. The existing routing mechanisms do not consider energy of nodes for data transmission. In this paper a novel approach is analyzed to improve the networks lifetime where the data transfer is based on the minimum hop count and residual energy of the mobile nodes. The analysis is carried out by using the network simulator and the simulation results shows that the proposed work provides an energy efficient routing in ad hoc networks.
Device Discovery Schemes for Energy-Efficient Cluster Head Rotation in D2DTELKOMNIKA JOURNAL
In this paper, novel device discovery approaches for the cluster head rotation, which is a state-ofthe-
art method for the Device-to-Device communication, are proposed. The device discovery is the
process to detect and to include new devices in the Device-to-Device communication. The proposed
device discovery is aimed to attain energy efficiency for the communication devices. We propose two
schemes for the device discovery: eNB-assisted and independent device discovery. Compared to previous
work, the proposed device discovery is utilizing the cluster head rotation method, to achieve better energy
efficiency. In this work, several simulations were performed and discussed for both schemes. In the first
simulation, the device energy consumption is examined. After that, the number of devices that get rejected
is studied. The device discovery processes in multi cluster head scenario, which is cluster head rotation,
are examined in this paper. The result of the simulation shows that eNB-assisted device discovery can
provide better energy efficiency. Also, the number of rejected devices of the eNB-assisted device
discovery is slightly lower than independent device discovery.
Energy saving in cooperative transmission using opportunistic protocol in MANETIOSR Journals
Abstract : In this thesis, we study the joint problems of cooperative link and diversity in A Mobile Ad-Hoc Network (MANET) with variable wireless channels. In MANET the wireless nodes are in group and infrastructure less in nature. The major problems faced by wireless communication in real time environment are that of interference and un-reliable communication links. Much research work has been done to overcome this by using various techniques. Cooperative communication and transmission side diversity in the network are the two of the techniques that help in reducing interference and communication link failures. We have also proposed a new technique to find the optimum route as a joint problem of the transmission power at the physical layer and the link selection at the network layer that incurs the minimum cost in terms of energy, no. of hops, available bandwidth and link quality (SNR), outage probability. Analytical results show that our cooperative transmission schemes (OMCTSP) achieves average energy saving of more than 80% than direct transmission.

IMPROVEMENTS IN ROUTING ALGORITHMS TO ENHANCE LIFETIME OF WIRELESS SENSOR NET...IJCNCJournal
Wireless sensor network (WSN) brings a new paradigm of real-time embedded systems with limited
computation, communication, memory, and energy resources that are being used fora huge range of
applications. Clustering in WSNs is an effective way to minimize the energy consumption of sensor nodes.
In this paper improvements in various parameters are compared for three different routing algorithms.
First, it is started with Low Energy Adaptive Cluster Hierarchy (LEACH)which is a famed clustering
mechanism that elects a CH based on the probability model. Then, work describes a Fuzzy logic system
initiated CH selection algorithm for LEACH. Then Artificial Bee Colony (ABC)which is an optimisation
protocol owes its inspiration to the exploration behaviour of honey bees. In this study ABC optimization
algorithm is proposed for fuzzy rule selection. Then, the results of the three routing algorithms are

An Efficient Algorithm to Calculate The Connectivity of Hyper-Rings Distribut...ijitcs
The aim of this paper is develop a software module to test the connectivity of various odd-sized HRs and attempted to answer an open question whether the node connectivity of an odd-sized HR is equal to its degree. We attempted to answer this question by explicitly testing the node connectivity's of various oddsized HRs. In this paper, we also study the properties, constructions, and connectivity of hyper-rings. We usually use a graph to represent the architecture of an interconnection network, where nodes represent processors and edges represent communication links between pairs of processors. Although the number of edges in a hyper-ring is roughly twice that of a hypercube with the same number of nodes, the diameter and the connectivity of the hyper-ring are shorter and larger, respectively, than those of the corresponding hypercube. These properties are advantageous to hyper-ring as desirable interconnection networks. This paper discusses the reliability in hyper-ring. One of the major goals in network design is to find the best way to increase the system’s reliability. The reliability of a distributed system depends on the reliabilities of its communication links and computer elements

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.
Shortest path algorithm for data transmission in wireless ad hoc sensor networksijasuc
Wireless sensor networks determine probable in military, environments, health and commercial
applications. The process of transferring of information from a remote sensor node to other nodes in a
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.
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.

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.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

1. INTRODUCTION
The area of Wireless Sensor
Networks has been explored highly by
researchers due to its varied applications in
real life such as in Environment monitoring,
security surveillances, habitatmonitoring,
underground mines and so on.[1],[2]
The major consideration of WSNs is
the limited power of the sensor nodes as
they are operated with small batteries. In
many applications they are randomly
deployed in harsh environment in which
human interaction is almost negligible so it

is very difficult for replenish their batteries.
The sensor nodes are prone to be failure as
they work in harsh environment. Therefore
for long run operation energy efficiency and
the fault tolerance of the sensor nodes plays
an important role in WSNs.[2]
Energy efficient multipath routing is
one of the efficient solutions for the same.In
multipath routing ,data packets are routed
through two or more paths,therefore reduces
chance of data loss at the recipient end node
BS[3].So multipath mechanism is highly
fault tolerable than the single path
routing[4].
Clustering is one of the best method
to save the energy in WSNs.During
clustering process,sensor nodes are grouped
and form the cluster on the basis of some
criteria.There is a cluster head(CH) in each
cluster and member sensor nodes always
forward the sensed data to its CHs, CHs
aggregate the received data and forward to
BS.CHs are usually selected from the
normal sensor nodes and therefore may die
quickly do to their extra work load such as
data aggregation and forwarding[6].
Here we discuss about a multipath
routing for relay based two tier WSNs in
which sensor nodes form the first tier and
the CHs from the second tier.Here the
algorithm is based on Genetic
Algorithm(GA) which is shown to be an
energy efficient.We consider several
parameters to make an algorithm energy
efficient such as distance between sending
and receiving node,hop count and distance
between next hop to BS.To derive an
efficient fitness function for the proposed
algorithm all these parameters are used.
An example of multipath routing for relay
based WSN with path is depicted in fig1.
In the above fig. there are 9 relay
nodes placed with a BS.For source node 1
there are two different paths first is 1 to 4 to

5 to BS and second path is 1 to 2 to 6 to 9 to
the BS.There is no common intermediate
node in both the path except source and
destination.So,both paths are disjoint in
nature.
2.RELATED WORK
C.Intanagonwiwat[8] have discussed
a query driven multipath routing protocol
known as Direct Diffusion(DD).Here
routing mechanism is started by flooding the
interest message in the network.Node
creates gradient to that node from which the
current message has been received and
several paths can be discobered between
each pair of source and sink nodes when a
node receives the interest
message.Whenever a node detects any event
then node forwards to the BS.Then node
select the best path based on the packet
reception performance over each path i.e the
path with minimum latency, for data
transmission.
[9]D.Ganeshan have proposed
multipath routing algorithms for WSNs and
compare the performance of multipath
routing algorithm with single path under
various parameter i.e network lifetime in
disjoint and braided multipath
mechanism.Here selection criteria for path
with minimum delay due to involvement of
minimum number of intermediate
nodes.Here, did not consider distance and
residual energy to make the algorithm
energy efficient.
Energy aware multipath routing and
reliable [10],The objective of this protocol is
to make the wireless sensor network energy
efficient and providing the reliable data
transmission by maintaining a backup path
from each source node towards the sink
node.When anode receives the service path
request message ,it transmits a service path
reservation message towards the BS to
confirm discover path.
Braided Multipath Routing
Protocol[9] is based on Direct Diffusion
protocol and design multiple paths to
provide high fault tolerance in the
network.In this protocol,the development of
path is initiated by BS by sending a message
to its neighboring node towards source
node.The process is repeated until entire
source nodes are not receive thw
message.During exchange of the message

source nodes also construct alternative
around their next hop.DD is based on this
protocol,all thr drawbacks of DD is also
exist here.Energy-Efficient and QoS-based
Multipath Routing Protocol(EQSR)[11] has
been proposed by J.Othman and
B.Yahya.The protocol provides reliability
and delay requirements of real-time
applications.The protocol provides
reliability by using the lightweight XOR-
based Forward Error Correction(FEC)
mechanism[12],which introduces data
redundancy in the data transmission process
and fulfill the delay constraints.Applying a
queuing model to manage real time and non
real time traffic for differentiation technique
by using EQSR. It uses flooding strategy
during the neighbor discovery phase and
may exaggerate the exact value of mutual
interference between different paths.In[13]
authors discussed a fault tolerant routing
scheme.This scheme consist two sub
processes 1)fault recovery process and
2)fault detection scheme.
3.SYSTEM MODEL
A. Energy model
In [17], Heinzelman et al. have
discussed an energy model and we use this
energy model for the simulation work. In
this energy model, distance plays a very
vital role and it acts as an important
parameter for the calculation of energy
consumption in both type of channels i.e.
multipath fading (mp) and free space (fs)
channels. The free space model is used,
when distance between transmitter and
receiver is less than a a threshold d0 value
and in other case we use multipath (mp)
model. To forward the l-bit data with
considering the distance d is represented as
follows (refer equation 1):
ET(l,d)= lEelec + l fsd2 d<d0
(1)
lEelec + l mpd4 d ≥ d0
The energy consumption by
electronic circuit is represented with Eelec.
The energy consumption by amplifier in free
space as well as in multipath model is
denoted by fs and mp respectively.
Moreover, When a node receives the data,
there are some energy consumption which is
expressed with the following equation.
ER(l)=lEelec

B. Network lifetime
Previously various definition of
network lifetime has been discussed in [19],
[20]. The general method to define the
lifetime of WSN is number of rounds until
the first node die. Beside it there are some
other methods i.e. certain number of nodes
die or certain % of nodes die or until any
node alive. Moreover there are some
scenario, where lifetime is considered until
the whole region is covered. In proposed
work, we consider the network lifetime until
the 50% of relay nodes alive.
4. TERMINOLOGIES
We have used following
terminologies to discuss the proposed
algorithm. „
• R = {r1,r2,...rm}: The set of relay nodes
and rm+1 represents the BS. • Dist(ri,r j): It
defines the aerial distnace between ri and rj.
• Range: It defines the communication range
of a relay node.
•ComCH(ri):it represents the set of relay
nodes and relay node belongs to this systetm
may exchange the information with node ri.
In other words, we can say
ComCH(ri)={rj | Dist(ri,r j) ≤ Range}
Where ri and rj ∈ R.
• K: It shows the number of various paths in
the network.
• Hop(ri) represents the number of next hops
required to reach to the base station from
relay node ri. Ifri can directly communicate
with BS, then Hop(ri) is 1. The recursive
definition of Hop(ri) is defined as follows:
Hop(ri)= 1 If Dist(ri,BS) ≤ Range
1+Hop(rj) Hop(rj)=Min{Hop(rk) |
Dist(ri,rk) ≤ Range,∀rk} Where
ri, rj and rk (-R.
A. Boot strapping
In proposed work, boot strapping is
one of the important operation. In this
operation entire relay nodes participate. It is
started by BS with forwarding the HELLO
message. The HELLO message consists of
ID of CH, residual energy, distance from BS
and hop count. The relay nodes broadcast
same message and those relay node(s) which
are in communication range update the
information and again broadcast it till every
relay node will not receive the same
message.

The proposed algorithm generates
energy efficient multipath from all relay
node to destination, so for the same we
design the cost function based on distance
between sender and receiver, hop count of
next hop and distance between next hop to
BS which as follows:
Cost(ri,r j) represents the incurred
cost to send data from ri to rj. The selection
of next hop by relay node ri is based on the
Cost function and ri always select that rj for
which the value of Cost is maximum. The
Cost function is energy efficient because its
value is maximum only when both type of
distance is minimum. As we know that the
energy consumption in sensor network is
directly proportional to square of the
distance. So, we can say that the next hop
selection based on this Cost is energy
efficient. Moreover, other parameter hop
count tries to select the next hop towards the
base station. Above mentioned Cost function
works only when j = BS. If a node able to
directly communicate with the BS then we
use following cost function.
5.GENETIC ALGORITHM
BASED MULTIPATH ROUTING
Many researchers applied GA for
clustering,routing and node deployment in
WSNs[21],[22].Here we discuss about the
multipath routing algorithm based on
GA.The discussion about various steps of
GA as follows with suitable example.
A.Chromosome representation and
Initial population
Chromosomes are represented as a
collection of relay nodes and length of the
chromosome is based on number of
paths(K).In fig1. There are 9 relay nodes
with BS and if we want to generate two
multipath from individual source to BS then
the length of chromosome is 18(9*2).In
chromosome,gene value at position 2
represents the next hop of relay node 2.In
path 1,the gene value at position 1 is 2 and
in second path the gene value at position 1 is

3.As an example for relay node 1 and 2 the
paths are
1 → 2 → 5 → BS and 2 → 5 → BS. Similarly
we can get second path from relay node 1
and 2 to BS is represented by 1 → 3 → 7 →
BS and 2 → 6 → 9 → BS.Shown in fig 2.
Fig. 2. Chromosome representation for subgraph
(refer Figure (1)) with two path.
B.Fitness Function
Fitness value represents the
qualifying criteria of a chromosome.In
proposed work we try to maximize the Cost.
I represents ith relay node ans j represents
the next hop of ith relay node.
C.Selection and Crossover
In this step of GA with higher fitness
value has been selected for the next
operation known as crossover.We use
Roulette-Wheel model for the selection of
chromosomes.
Suppose, for the crossover operation two
random values (i, j) are generated then i
represents the ith position from left and j
represents the m + jthposition from left.
Where 1 ≤ i ≤ m, m+1 ≤ j ≤ 2m and m
represents the number of relay nodes. The
whole process of 2-point crossover
operation is shown in following figure (refer
Figure 3).
Fig. 3. Crossover operation.
In fig.3,2-point crossover has been
used because there are two path.Suppose
there are K multiple path in the network then
the length of chromosome is m*K.In this
situation K-point crossover operation is used
and the crossover point is represented by a
vector as <i1,i2,....ik>.The range of i1 is
between 1 to m and range of i2 is between
m+1 to 2m similarly the range of ik is
between(K-1)m+1 to Km.

D.Mutation
For the mutation we select that relay
node which contributes minimum cost value
in fitness.After selection of this
node,algorithm tries to replace it with a valid
node.
6.SIMULATION RESULTS
In proposed algorithm. For
performing the simlation, we have used
MATLAB and C on Intel Dual core
processor processor with T9400 chipset, 3
GHz CPU and 6 GB RAM running on the
platform Windows 8. We have designed a
network scenario named as WSN#1. The
size of WSN#1 is 150×150 square meter
area and position of the base station is taken
as (75, 75). The desired parameters for
experiment has been taken as same
discussed in [17]. we have considered an
initial population of 100 chromosomes for
the execution of proposed algorithm . With
the help of Roulette Wheel selection model
8% chromosomes has been selected for the
crossover operation, . The algorithm
executed up to 65 epochs, but it returns the
optimal results after 37 epochs. After
completion of crossover operation, we have
applied uniform mutation operation to
strengthen the chromosome.

No.of relay nodes
Fig 5.Network lifetime in WSN#1 with two paths
The network lifetime of scenario
WSN#1 has been depicted in Figure 4 and
from the figure we can see the network
lifetime in both paths. We have calculated
the network lifetime by varying the number
of gateways from 10-50 and it is assumed
that network alive until 50% nodes will not
die. Selection of next hop is based on cost
function and cost function considers the
distance and hop count of possible next hop.
Therefore, there is a higher probability that
next hop always towards the base station
with minimum distance.
The Figure 5 represents the energy
consumption per round. The results in
Figure 5 has been calculated by varying the
number of relay nodes from 10 to 50.
7.CONCLUSION
Multipath routing is one of the
prominent method to totolerate the fault in
sensor network, .Therefore,in this research
article we have presented multipath routing
algorithm for WSNs using GA. Here, we
have discussed all the basic steps of GA
with suitable example. For the experimental
purpose, we have executed the algorithm by
varying the number of relay nodes from 10
to 40 and pictorially represented the two
different path for 40 relay nodes. Moreover,
for two different paths we have also
represented the network lifetime in terms of
round. However, in proposed work we did
not consider the balancing of energy
amongst the path as well as relay nodes. In
future, we will consider the Quality of
Service (QoS) parameters with balancing the
energy amongst paths and relay nodes in
both static and mobile scenario.
