ENERGY EFFICIENT LOAD BALANCED ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORKS

Due to the enormous applications of wireless sensors, the research on wireless sensor networks remains active throughout the past two decades. Because of miniaturization of sensor nodes and their limited batteries, the energy efficiency and energy balancing are the demand in-need to extend the life time of sensor networks. This study proposes an energy-aware directional routing protocol for stationary wireless sensor network. The routing algorithm is non-table driven, destination aware and packet forwarder nodes are selected on the basis of admissible heuristic logical distance, and packet forwarding direction is also determined in very simplistic method. The algorithm is designed for 1-hop, 2-hop and ‘2-hop & 1-hop combine’ communication method. The energy balancing mechanism of this paper is based on two state thresholds and simulation result shows its superiority over the existing directional routing protocols of wireless sensor networks.
