The particular goals of this thesis work are to: Develop and design a simulation model and scenarios. Perform a simulation with different metrics and different scenarios. Analysis of the results in static and mobile environment. Comparative study has been done on the basis of simulation results. Deriving a conclusion on basis of performance evaluation the improve its performance by proposed methodology.INTRODUCTION TO WSN Wireless sensors network (WSN) is the collection of homogenous, self organized nodes known as sensor nodes. These nodes have the event sensing capabilities, data processing capabilitiesReactive versus Proactive routing approach Proactive Routing Protocols  Periodic exchange of control messages  immediately provide the required routes when needed  Larger signalling traffic and power consumption. Reactive Routing Protocols Attempts to discover routes only on-demand by flooding Smaller signalling traffic and power consumption A long delay for application when no route to the destination available Hybrid combination of proactive and reactiveAd hoc On-Demand Distance Vector (AODV) Allows communication between two nodes via intermediate nodes. It reduces network load by maintaining only currently active routes and dynamically updates routing information at each intermediate node.To establishing a route between source node to destination, AODV routing protocol using Route discovery process along which Route Request (RREQ) message are broadcasted to its neighbors.Dynamic Source Routing (DSR) It is based on concept of source routing. Each node maintains a route cache to store all possible learned routes. It using two main mechanisms: Route discovery and Route maintenanceRoute Discovery process is initiated only if desired route can not found in route cache.Optimized Link State Routing Protocol Proactive & Table-driven Link State Routing Each node expands a spanning tree Each node can obtain the whole network topology Utilizes a technique to reduce message flooding Multi Point Relaying (MPR)Literature Review Kahina Ali et al. 1 This paper analyzed the performance of AODV, DSR and OLSR with varying the node density using NS- 2 simulator. Simulation results indicate that DSR shows the lowest performance as compared to AODV routing protocol. Jing Zuo at al. 2 This paper analyzed the performance of AODV and OLSR with varying number of Vehicle-node density using OMNET++ simulator. Simulation results indicate that AODV shows better performance as compared to OLSR routing protocol.S. I. Chowdhury et al. 3 This paper analyzed DSR and AODV in terms of packet delivery fraction, average end to end delay and network load using WSNMobiSim. In this paper less numbers of nodes is used for analysis. Sherali Zeadally et al. 4 This paper gives an brief overview of WSN architecture, its standards, its security issues. This paper also provides brief overview of various WSN simulation models, tools, and platforms.Literature Review Continue…… Monika et al. 5: This paper analyzed the performance of AODV and DSR routing protocols for WSN with and without RSU (Road Side Unit). For performance evaluation of considered protocols they used Estinet Simulator. After getting simulation results they conclude that throughput was highest for AODV as compared to DSR with varying number of nodes soAODVperformedbetterthanDSR. Amit N. Thakare et al. 6: In this paper authors analyzed the performance of AODV and DSR routing protocols using ns-2 simulator with Random Waypoint mobility model. After getting simulation results they conclude that packet loss of DSR is higher as compared to AODV and ratio of packet received was higher for AODV as compared to the DSR routingprotocol.Scenarios Used Scenarios Name No. of Mobile Nodes Protocol Used Scenario 1 100 DSR Scenario 2 100 OLSR Scenario 3 150 DSR Scenario 4 150 OLSR Scenario 5 200 DSR Scenario 6 200 OLSR Scenario 7 250 DSRSimulation Statistics Simulation Parameters Examined OLSR and DSR Protocols Number of Mobile 100,150,200 and 250 & Static Nodes Simulation Area 45004500 meters
