Dynamic Load Balancing Protocol (DLBP) for Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are resource-constrained networks that have been applied in many applications. Many researchers have presented routing protocols to prolong the lifetime of WSNs. In this paper we present a Dynamic Load Balancing Protocol (DLBP) that exploits all network nodes to achieve load balancing and prolong the lifetime of WSN. DLBP has succeeded to build a load balanced tree, eliminate the need for control messages during data routing, keep the load of the WSN balanced during data routing, send messages to next hops without route-discovery delay, quickly maintain and fix network errors and failures. Simulation results show that the network success ratio has reached 97%. Routing overhead has decreased by 72% and network lifetime has increased by 20% comparing to other tested algorithms.
