Scenario Based Analysis of AODV and DSR Protocols Under Mobility in Wireless Sensor Networks

Abstract

Wireless sensor networks have gained considerable attention in the past few years. They have found application domains in battlefield communication, homeland security, pollution sensing and traffic monitoring. As such, there has been an increasing need to define and develop simulation frameworks for carrying out high-fidelity WSN simulation. For our simulation based study we have considered three different scenarios where a Adhoc routing protocol can be applied, namely a) Phenom nodes with Mobility, Sensor nodes with mobility while the SINK node is stationary b) Phenom nodes with Mobility, Sensor nodes are stationary and Sink node is stationary c) Phenom nodes are stationary, Sensor nodes are stationary and SINK node is stationary. We have considered AODV and DSR as the Adhoc routing protocols for comparison in these scenarios. Simulation has been carried out by using qualnet 5.0.2 simulator. The matrices used for this simulation are packet Deliver Ratio to SINK, Average End to End Delay to SINK, Overhead, Throughput. Finally, through our analysis we show the various intricacies that are associated with Adhoc routing protocols when used in a sensor environment. We also list the various problems we faced while simulating the routing protocols in each of the scenarios.
