Load balancing system with sub-network management in wireless sensor networks

Abstract

One of the important parameter to evaluate the performance of wireless sensor network (WSN) is "overall network lifetime". Load balancing is the energy maintenance method which can distribute huge data traffic evenly to prolong the whole network lifetime. In this paper, we present the load balancing system with mobile robot as a subnetwork's mobile sink to maximize network lifetime. The field test and simulation results demonstrate the performance of our system.
