Abstract
Wireless sensor network (WSN) is a system composed of a large number of micro-sensors nodes. This network is used to collect, compute and communicate the data to a base station (BS). Energy is the major constraint of sensor networks. So it’s necessary to have which means energy efficient routing protocol should be employed to offer a long-life work time. To achieve the aim, we need not only to minimize total energy consumption but also to balance the load in the network. Researchers have proposed many protocols such as LEACH, BCDCP, ELCH, and GSTEB. In this paper, we propose a Self-Organized Hierarchical Dynamic Routing Protocol (SHDRP) which builds a routing tree using a process where, for each round, BS assigns a coordinator and broadcasts this selection to all sensor nodes. Subsequently, each node selects its intermediate head by considering only itself and its neighbors’ information, thus making SHDRP a dynamic protocol. Simulation results show that SHDRP has a better performance than other protocols in balancing energy consumption, thus prolonging the lifetime of WSN.
