Load Balancing Routing for Wireless Sensor Network in 2D Mesh

Abstract

In this article, we deal with the load balancing routing problem for wireless sensor network (WSN) in two-dimensional mesh. Load balancing routing is very important for the WSN. However the existing balancing routing algorithms mostly focus on the energy balance and most of them are based on clustering technology. It needs time and energy to construct clusters for clustering technology. We propose a load balancing routing algorithm in 2D mesh WSN. The 2D mesh topology is popular due to its simple structure. It has no need to construct clusters and cluster heads. We deploy the base station at the four corners of 2D mesh WSN, and let the base stations bear the main loads. Our routing algorithm significantly reduces the center nodes' loads and has a very perfect load balance in the centre networks which greatly increases the network lifetime.
