Performance evaluation of wireless sensor networks for different radio models considering mobile event

Abstract

In this paper, we consider the behavior of a wireless sensor network for TwoRayGround and Shadowing radio models for the case of mobile event. By means of simulations, we analyse the performance of AODV protocol. In the previous work, we considered that the event node is stationary in the observation field. In this work, we want to investigate how the sensor network performs in the case when the event node moves. The simulation results show that the shadowing phenomena, by destroying the regularity of the network, reduce the mean distance among nodes and at the same time increase the interference level and the latency of packet transmission. We found that for mobile event, the Goodput and routing efficiency of TwoRayGround is better than Shadowing, but the Depletion of Shadowing is better than TwoRayGround.
