Use of mobile devices for data collection in Wireless Sensor Networks (WSNs) has recently drawn much attention. Controlled sink mobility has been shown to be beneficial in energy conservation and lifetime prolongation. In this paper, the authors aim at studying the Multi-hop Uneven Hierarchical Routing Protocol (MUHRP) using different mobile sink strategies. They first analyze the performance of multi-hop uneven hierarchical routing protocol with a fixed sink node. Then to measure the network performance, they use a mobile sink node, replacing the fixed sink node, to collect fused data packets from cluster heads. Network performance using their proposed protocol is validated through simulation experiments using MATLAB.
