With the rapid growth of wireless communication infras,,tructure over the recent few years, new
challenges has been posed on the system and analysis on wireless adhoc networking. Implementation of
MIMO communication in such type of network is enhancing the packet transmission capabilities. There
are different techniques for cooperative transmission and broadcasting packet in MIMO equipped
Mobile Adhoc Network. We have employed a model network in the OPNET environment and propose a
new scheduling algorithm based on investigating the different broadcasting algorithm. The new
broadcasting algorithm improves the packet transmission rate of the network based on energy
performance of the network and minimizes the BER for different transmission mode which is illustrated
in this paper. The simulations are done in MATLAB and OPNET environment and the simulated result
for the packet transmission rate are collected and shown in the tabular form. Also simulate the network
for generating a comparative statement for each mobile node. And performance analysis is also done for
the model network. The main focus is to minimize BER and improve information efficiency of the

Advanced delay reduction algorithm based on GPS with Load Balancingijdpsjournal
A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless
links, to form an arbitrary topology. The nodes are free to move arbitrarily in the topology. Thus, the
network's wireless topology may be random and may change quickly. An ad Hoc network is formed by
sensor networks consisting of sensing, data processing, and communication components. There is frequent
occurrence of congested links in such a network as wireless links inherently have significantly lower
capacity than hardwired links and are therefore more prone to congestion. Here we proposed a algorithm
which involves the reduction in the delay with the help of Request_set created on the basis of the location
information of the destination node. Across the paths found in the Route_reply (RREP) packets the load is
equally distributed

In this paper we have analyzed energy efficient neighbour selection algorithms for routing in wireless
sensor networks. Since energy saving or consumption is an important aspect of wireless sensor networks,
its precise usage is highly desirable both for the faithful performance of network and to increase the
network life time. For this work, we have considered a flat network topology where every node has the
same responsibility and capability. We have compared two energy efficient algorithms and analyzed their
performances when all sensor nodes in a network have either homogeneous or heterogeneous energy with
increase in number of nodes, time rounds and node failures.

One of Machine Type Communication (MTC) applications is Wireless Sensor Network
(WSN). WSN is an intelligent network application system to collect, integrate, and transmit data
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
Clustering Hierarchy (LEACH). In this paper, High Altitude Platform (HAP) is used to replace
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
delivered to the HAP will be greater.

Improved Power Aware Location Based RoutingIOSR Journals
Abstract : With rapid growth in wireless Ad Hoc networks, Quality of service factor has drawn a great attention of researchers. Whereas network topology of wireless networks constantly changes, resources like bandwidth and energy are also limited. As power is very important factor for the proper working of Ad Hoc networks, need of the time is to research about efficient utilization of power. In the paper, we improve LAR (Location-Aided Routing), one of the most famous location based routing methods, which uses GPS technique to get information about the location of mobile node. Our new protocol considers both areas of routing and power. At first, propose a more efficient routing method which finds more stable paths .Secondly, a power aware method is proposed to have a prior knowledge about the remaining battery backups of all the intermediate nodes so that the nodes with battery backups equal to or greater than the minimum threshold power are the part of path between source and destination. This work presents an efficient approach for providing QOS in power aware scenario. Keywords: Ad hoc networks, Average power, Expected Zone, Requested Zone, Threshold power
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).
Ad hoc networks are self-configuring networks and each node executes routing functionalities by itself;
they are powered by battery, which is prone to decrease with time. In this paper, a power aware routing
algorithm called Dynamic path switching is proposed which attempt to extend the lifetime of network in
MANET. It creates a new path based on the energy level of the nodes. Along with DPS the Transmission
power control technique is incorporated which varies the transmission power based on the distance. It
reduces power consumption further. The proposed techniques are incorporated in Zone Routing Protocol
(ZRP) and simulated by using NS-2 simulator to obtain the QOS parameters.
Advance in the WIRELESS SENSOR NETWORK (WISENET) technology is energy efficient routing protocols that promises a wide range of potential applications in both civilian and military areas. In the WISNET the sensor node have a limited transmission range and their processing and storage capabilities as well as their energy sources are limited. So the Equalized Cluster Head Election Routing Protocol (ECHERP) and PEGASIS with Double Cluster Head (PDCH) pursues energy conservation through balanced clustering for Energy Efficiency. In WSN, energy efficient routing protocol is important to increase the network lifetime. ECHERP and PDCH both protocol claims to be energy efficient.
The Impact of Signal Strength over Routing Protocols in Wireless NetworksDr. Amarjeet Singh
In ad hoc routing protocols the source node
may need an intermediate nodes to transmit the packets into
the destination if the destination is not within transmission
range of the source. This paper studies the impact of signal
strength of nodes over ad hoc routing protocols and explains
an important effect of signal strength on ad hoc routing
protocols in four different directions including the routes and
the nodes. As a result the study give an important
improvement in ad hoc routing protocols when using signal
strength compared to other ad hoc routing protocols without
considering signal strength.

An enhanced energy-efficient routing protocol for wireless sensor networkIJECEIAES
Recent few years, Wireless Sensor Network (WSN) has been an increasingly important technology that has been applied in almost all domains, even in complex environments where human activity is impossible. In WSN, various factors are impacted energy consumption, such as communication protocols, packet data transmission, and limited battery. So, the lifespan of the WSNs is limited. In this context, energy efficiency is the factor most attracted by many researchers. In this paper, we proposed a new improved LEACH routing protocol. This proposed protocol based on the current energy to select cluster-heads, and it uses a root cluster-head with more current energy and low distance to the sink to gather all data, then sends it to the sink. The simulation results in MATLAB confirmed that the proposed algorithm performed better than the conventional LEACH protocol, and increased the network lifetime in WSN.
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.

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 (2
2n)
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).

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.

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

IMPLEMENTING PACKET BROADCASTING ALGORITHM OF MIMO BASED MOBILE AD-HOC NETWOR...IJNSA Journal
With the rapid growth of wireless communication infras,,tructure over the recent few years, new challenges has been posed on the system and analysis on wireless adhoc networking. Implementation of MIMO communication in such type of network is enhancing the packet transmission capabilities. There are different techniques for cooperative transmission and broadcasting packet in MIMO equipped Mobile Adhoc Network. We have employed a model network in the OPNET environment and propose a new scheduling algorithm based on investigating the different broadcasting algorithm. The new broadcasting algorithm improves the packet transmission rate of the network based on energy performance of the network and minimizes the BER for different transmission mode which is illustrated in this paper. The simulations are done in MATLAB and OPNET environment and the simulated result for the packet transmission rate are collected and shown in the tabular form. Also simulate the network for generating a comparative statement for each mobile node. And performance analysis is also done for the model network. The main focus is to minimize BER and improve information efficiency of the network.

In this paper we have analyzed energy efficient neighbour selection algorithms for routing in wireless sensor networks. Since energy saving or consumption is an important aspect of wireless sensor networks, its precise usage is highly desirable both for the faithful performance of network and to increase the network life time. For this work, we have considered a flat network topology where every node has the same responsibility and capability. We have compared two energy efficient algorithms and analyzed their performances when all sensor nodes in a network have either homogeneous or heterogeneous energy with increase in number of nodes, time rounds and node failures.

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

The main aim of energy efficient routing is to
minimize the energy required to transmit or receive packets also
called as active communication energy. Inactive energy is the
energy which not only tries to reduce the energy consumed
when a mobile node stays idle but also listens to the wireless
medium for any possible communication requests from other
nodes. To conserve energy, many energy efficient routing
protocols have been proposed. Networks of small, inexpensive,
disposable, smart sensors are emerging as a new technology with
tremendous potential. Wireless sensor networks can be randomly
deployed inside or close to phenomenon to be monitored. The
advantage of these networks is the fact that they are selfconfiguring,
which means that a sensor network can be deployed
randomly on a battlefield, in a disaster area or in an inaccessible
area without the need for human intervention. The energy
supplies of nodes are not replenished or replaced and therefore
nodes only participate in the network for as long as they have
energy. This fact necessitates energy efficiency in the design of
every aspect of such nodes. Energy consumption in sensor nodes
occurs mainly due to computational processing and, to a greater
extent, communication. The routing protocol employed by these
sensor nodes can minimize the number of transmissions that
nodes make as well as the computational complexity of routing
path selection. It is therefore of critical importance that the
routing protocol be designed with energy efficiency in mind.
Energy Efficient Wireless Sensor Network Using Network Coding Based Multipath...IJERA Editor
Network Coding is most promising aspect of WSN. This Network Coding method is combined with multipath routing protocol to form NCMR protocol.(network coding based multipath routing protocol).This protocol is used to obtain energy efficient wireless sensor network.. These protocol leads to decrease the number of constrain routes & the total time of transmission. This protocol is applied on unicast and multicast network separately. And comparison is done with traditional multipath routing protocol for same unicast and multicast network. Simulation result shows energy consumption of NCMR multicast is lower than NCMR unicast and also than TMR unicast as well as multicast. This work is proved by the simulation analysis results. The used multipath model is based on braided multipath routing, and the network coding method is random linear network coding (practical network coding). In braided network multiple paths to the sink nodes are created for each source node, and the packets encoded at source nodes are transmitted through the braided multipath network model. Then, intermediate nodes re-encode these received packets and transfer these new packets to next cluster. Finally, the multiple sink nodes decode the packets received from different paths and recover the original data. Results of the analysis show that multicast NCMR provides more reliability. We compare multicast NCMR routing protocol with NCMR unicast & also with traditional multipath routing protocol for unicast and multicast networks, in terms of the packet loss, energy consumption, successful delivery ratio & end to end delay when a packet is transmitted Some special simulations are carried out specially for NCMR multicast i.e. effect of number of nodes on energy consumption, packet loss & end to end delay.
Nearest Adjacent Node Discovery Scheme for Routing Protocol in Wireless Senso...IOSR Journals
The broad significance of Wireless Sensor Networks is in most emergency and disaster rescue
domain. The routing process is the main challenges in the wireless sensor network due to lack of physical links.
The objective of routing is to find optimum path which is used to transferring packets from source node to
destination node. Routing should generate feasible routes between nodes and send traffic along the selected path
and also achieve high performance. This paper presents a nearest adjacent node scheme based on shortest path
routing algorithm. It is plays an important role in energy conservation. It finds the best location of nearest
adjacent nodes by involving the least number of nodes in transmission of data and set large number of nodes to
sleep in idle mode. Based on simulation result we shows the significant improvement in energy saving and
enhance the life of the network

Energy Saving Multipath Routing Protocol for Wireless Sensor
Networks
Yash Arora*, Himangi Pande**
*(Department of Information technology, Pune University, Pune, India)

ABSTRACT : The Wireless sensor networks have many characteristics such as limited energy resources, low
bandwidth and unreliable links. Due to these characteristics there are many challenges in the design of sensor
networks. Routing in WSN is very challenging task. Multipath establishes several path for data transmission
rather than single path. Due to this data delivery is high.
In this paper, we propose energy saving multipath routing protocol (ESMRP). ESMRP make use of load
balancing algorithm to transfer the data. ESMRP calculates node strength to discover its next best hop. Our
protocol uses two versions, in the first version, data is transmitted through single path, if some path failure
occurs or discovered path node strength goes below 15% of alternative path node strength then it will switch to
next alternative path. In the second version of ESMRP, message is split into various segments and some
correction codes are added to these segments. After that these segments are transmitted across multiple paths.
Simulation results shows that the proposed protocol is more energy saving than previous protocol in
providing efficient resource utilization.
Keywords – Correction codes, Energy Saving, Load Balancing, Multipath Routing, Wireless Sensor Networks
I. Introduction
Wireless sensor network consists of various
smart tiny devices called sensor nodes and these
nodes monitor the environment by measuring
parameters such as temperature, pressure humidity
that are used in target tracking, healthcare services
etc. Sensor nodes sense target area and transmit their
collected information to the sink node. Resource
limitations of the sensor nodes, unreliability of low-
power wireless links in combination with various
performance demands of different applications
impose many challenges in designing efficient
communication protocols for wireless sensor
networks. The main aim is to discover ways for
route setup and reliable relaying of data from the
sensor nodes to the sink to increase the network
lifetime. Numerous routing protocols have been
proposed by researchers to improve performance of
many applications.
Routing protocols considers all the characteristics
of sensor nodes [1, 2, 3]. The routing protocols can
be classified as negotiation based, query based, QOS
based, and multipath based [4]. The negotiation
based protocols eliminate the redundant data by
including high level data descriptors in the message
exchange. In query based protocols, the sink node
initiates the communication by broadcasting a query
for data over the network. The QOS based protocols
makes a tradeoff between the energy consumption
and some QOS metrics before delivering the data to
the sink node. Finally, multipath routing protocols
use multiple paths rather than a single path to
transfer data from source to sink. Multipath routing
establishes multiple paths between the source-
destination pair. In single-path routing each source
sensor sends its data to the sink via the shortest path.
In single path new route discovery process is
initiated, which increases energy consumption. Node
failure also causes packets to be dropped and may
cause a delay in delivering the data to the sink, thus
the real-time requirements of the multimedia
applications are not met. Multi-path routing
increases the number of possible routes and through
this it increases the robustness and throughput of the
transmissions. Multipath routing is commercial for
heavy load scenario than single path. Multipath
routing is mainly used either for load balancing or
for reliability. Load balancing can be achieved by
balancing energy utilization among the nodes
improving network lifetime. The paper is organized
as follows: Section 2, describes Related Work.
Section 3, describes Proposed Protocol. Section 4,
describes Performance Evaluation, Section 5,
defines, Conclusion.
II. Related Work
The routing in wireless sensor network is
challenging task now a days. There exists several
routing algorithm but our focus is to develop routing
algorithm that is more energy saving and increases
the life of sensor nodes. There are various proposals
being made in this area. In this section we present
some work being done to proposed protocol.
The author in [5] proposed N to 1 multipath
routing algorithm. This protocol uses flooding

mechanism to find multiple node-disjoint paths from
every sensor node to the common destination. This
flooding mechanism is used to construct a spanning
tree and discover several paths from sensor nodes
towards a single sink node. Multipath is used to
distribute the data. The N-to-1 routing protocol does
not consider node residual energy during
construction phase. This protocol also lacks in
efficient use of each node resources.
The author of [10] proposed multiple node-
disjoint paths between the sink and source nodes are
discovered. Load balancing algorithm is being
implemented for distribution of traffic over multiple
paths and these multiple paths are discovered based
on their cost. Cost of each path is calculated by the
energy levels and also the hop distances of nodes.
This protocol support node with limited mobility.
The author of [11] uses two versions of protocol
REER-1 uses a single path among set of discovered
paths to transfer the data, when path cost falls below
a certain threshold, then it switches to the next
alternative path. In REER-2 message is split into N
segments of equal size and correction is added to
that segments and transmit it over multiple paths. In
this protocol it drains out node battery through
which delay in data transfer takes place.
In our proposed protocol we try to utilize node
resources through Load balancing and to make it
more energy saving and increases delivery ratio.
III. Proposed Protocol
In this section, we first explain some
assumptions. Then we will define various
constituent parts of the proposed protocol.
3.1. Assumptions
We assume that N identical nodes are randomly
distributed in the sensing environment. Each sensor
node is assigned a unique ID. Each sensor nodes
have same battery power. Furthermore, we assume
that each sensor node is able to compute its residual
energy, and its available buffer size, as well as
calculate signal-to-noise ratio (SNR) between itself
and neighbouring nodes.
3.2. Node Strength
The Node Strength is based on the three factors
residual energy, available buffer size and signal to
noise ratio. Node Strength is used by the node to
select the best next hop during route discovery
phase. Let Nx denotes the set of neighbouring nodes
of x. Then our node strength includes:
Next hop = max y Nx {α Eresd, y +β Bbuffer, y + γ
Iinterference, xy} (1)
Where, Eresd, y is the current residual energy of node
y, where y Nx, Bbuffer, y is the available buffer size
of node y, and Iinterference, xy is the SNR for the link
between nodes x and y.
The total node strength Ctotal for a path P consists
of a set of K nodes is the sum of the individual node
strength l (xy)i, iK along the path. Then we have:
Ctotal P = i (2)
3.3. Route Discovery Phase
Route discovery idea is obtained from direct
diffusion [6], the sink node create set of neighbours
that forward data towards the sink from the source
node. The constructed multipaths have no common
nodes except the source and the destination. Node-
disjoint paths are fault-tolerant so there is a
minimum impact to the diversity of the routes [12].
Route discovery includes several phases explained
as:
3.3.1. Initialization Phase
Each sensor nodes gain some information
concerning its neighbouring nodes. At the first step
each nodes broadcasts a HELLO message to know
which of its neighbours can provide it with the
highest quality data. Each node updates its
neighbouring table. The neighbour table, also
contains link quality(in term of signal-to-noise
ratio), Residual energy of next node and free buffer.
HELLO message structure shown in Fig. 3.3.1
contains Hop Count that gives the distance of
message from its originator. Source ID field contains
the ID of the message originator.
Source
ID

Count

Figure 3.3.1: Message structure
3.3.2. Primary Route Discovery Phase
Each sensor node computes the Node Strength for its
neighbouring nodes. Next, using the node strength
sink node locally computes its next best node and
send RREQ message to nest next hop. This process
continues until reaches to source node.
3.3.3. Alternate Route Discovery
The sink node sends RREQ message to next
neighbour node. If the node is already in use then in
used node will send INUSE message and then the
node will find another node from table.
3.3.4. Data Transmission through Load Balancing
We propose a load balancing algorithm for better
utilization of each route resources. After discovering
multiple paths, source node begins to transmit data
message to sink node. We propose two versions of
the protocol to route data to sink node. In first
version, Data transmission through single path
using Load balancing, ESMRP1, and the idea
behind [13] is being used. Each time we send
Route_Reply packet across the path to update node
strength of each node. This Route_Reply packet
contains some information regarding its traversed
path. This information is useful to apply efficient
load balancing algorithm. Data transmission
continues over the primary path until its strength

www.ijera.com 154 | P a g e
fallen below the next available path, and then next
available path is being used, and so on. If a node
fails or any rote failure occurs, error message is
initiated to the source node. Source node then
removes the error route and selects the next best
available paths from the routing table and resumes
the transmission process. If all the routes contained
in the routing table are failed then source broadcast a
request message for the sink to initiate a route
discovery message. This technique improves the
message delivery and improves resource utilization
that always finds a way to deliver the data to the
sink.
In the second version, Data transferring through
multipath routes using Load balancing ESMRP2.
In this we select routes from N available routes
discovered in route discovery. We assume that each
path is associated with some rate pi (i=1,2, .. n). pi is
the probability of successfully delivering a message
to the destination. The number of required paths is
calculated as:
K = xα (√ ) (3)
xα is the bound from the standard normal
distribution. The message to be transferred is split
into segments (S1, S2, and S3...SN-1) and some
error control bits are added to the original message.
These segmented messages are sent out across the k
best available paths. While performing all above
operations, Route_reply packet is send to update
strength of each node and hence total node strength
of each path. This information is used to compare
total strength of path used in subset of k with total
strength of path available in N. If there is a change to
their last broadcast value then path having low cost
value in subset of k will be replaced with path
available in N. A similar operation is applied
according to the residual battery and node strength
values whenever they are changed more than 10%
compared to their last broadcast values.
IV. Performance evaluation
We used NS2 [19] to implement our routing
protocol and compare it with REER (Robust and
energy efficient multipath routing protocol).
A two dimensional square area is used for node
deployment. The network consists of Common
sensor node, access point and sink node. Nodes are
randomly deployed in area. No of common sensor
nodes sense the data from temperature and carbon
monoxide application data generator. Source node
sends the request message to the neighbouring nodes
to discover multiple paths. Total node strength of
each path is calculated and data transfers take place.
The disseminating time, takes transmission power,
receiving power, initial energy of various types of
node in network is same.
The main experiment parameters are Number of
Nodes, Topology size, Initial energy, Sending
power, receiving power, packet size. Parameters like
Number of Nodes can vary at the time of
implementation and different scenarios can be
studied and compared to get the optimized results.
Our simulation environment consists field 300m
x 300m containing N sensor nodes (N varies from 50
to 300 nodes) randomly deployed. Radio
transmission range is set to 25m for all identical
nodes. Table 4 shows the simulation parameters.
In the rest of this section, we evaluate our
protocol in multihop topology. The performance
metrics used in the evaluation are the average energy
consumption, average delivery ratio and average
delay.
4.1. Average Energy Consumption
It is defined as the average energy consumed by the
nodes used in message transfer from source to sink
node. Fig. 4.1(a) and 4.1(b) shows the results for the
energy consumption. From the Fig. 4.1(a), we
observe that there is a save in energy of both
versions of protocol ESMRP1 using load balancing
protocol over REER protocol. As the network size
increases, ESMRP1 becomes more stable than
REER-1 protocols. In Fig. 4.1(b), ESMRP2
consumes less energy than REER-2, because of the
load balancing, which updates node strength of path
every time transmission takes place. This approach
helps nodes in the path not to drain their constraint
energy resources with continual use of same route
and hence achieves longer lifetime.

4.2. Average Delivery Ratio
The average delivery ratio is defined as the number
of packets generated by the source to the number of
packets received by the sink node. Fig. 4.2(a) &
4.2(b) shows the average delivery ratio. As the
network size gets large, there are more available
nodes, and hence more routes, to forward data,
resulting slight increase of the delivery ratio.
ESMRP1 is showing better results than REER-1
protocol but as network size increases its
performance degrades. ESMRP2 shows good
performance, because the multiple paths are used
simultaneously to transfer data and better path and
resource utilization.

4.3. Delay
The delay is the time required to transfer data from
source node to the sink node. Fig. 4.3(a) & 4.3(b)
shows the delay of the compared protocols. The
delay for all tested protocol increases with the
increase in network size, but still our protocol
ESMRP using load balancing protocols shows good
performance even for large network sizes. As in our
protocol it will not wait for nodes battery to get
drained, as every time updated node strength is
received through Route_Reply. Thus a minimum
tradeoff with delay should be made to reduce the
energy expenditure.

V. Conclusion
In this paper, we proposed an energy saving
multipath routing protocol (ESMRP) to improve data
delivery ratio and decreases delay. ESMRP
discovers multipath for transmission of data from
source to sink. We have also used load balancing
algorithm that make effective use of resources and
node strength is used as routing metric. Through
computer simulation, we have evaluated and studied
the performance of our routing protocol and
compared it with REER protocol.
Simulation results have shown that our protocol
achieves more energy savings, lower average delay
and higher data delivery ratio than REER protocol.
