Performance Analysis of Sinks Mobility in Geographic Routing for Wireless Sensor Networks
This paper presents a performance analysis of sinks mobility in geographic routing based on performance evaluation of two geographic routing protocols namely GPSR with static sinks and Elastic with mobile sinks. Among the scenarios, we observe also the impact of using multi-mobile-sinks, in addition to the effect of mobility model through changing the sink’s trajectory and speed. We analyze the performance results by calculating the delivery ratio of the transmitted packets, as well as the average delay of transmission and the number of hops necessary to transmit successfully a packet from the source to the sink. We show that mobile sinks can play a major role in prolonging the network lifetime and the efficiency of a geographic routing protocol.
