Scenario Based Simulation Study of Ad Hoc Routing Protocol's Behavior in Wireless Sensor Networks

This paper investigates and undertakes simulation based study of adhoc routing protocols in wireless sensor networks. 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. We wanted to consider a table driven routing protocol like DSDV but it was not able to scale beyond 80 nodes in the very first scenario itself. As we wanted uniformity across all the scenarios we opted out of table driven routing protocols like DSDV, even though DSDV could have been used in the third scenario. 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.
