DVD Based Moving Event Localization in Multihop Cellular Sensor Networks

In this paper, we consider moving event localization using data collected from a Multihop Cellular Sensor Network (MCSN). The main contribution of the paper is a novel structure- free Distributed Velocity Dependent (DVD) waiting time based protocol. We compare the performance of the proposed DVD protocol with that of a Centralized approach and the existing Randomized Waiting time (RW) protocol. Simulation results show that DVD exhibits a performance superior to RW with respect to center of event localization error and end-to-end delay. We also present simulation results on the the sensitivity analysis based comparison between DVD, RW and the Centralized scheme.
