Novel Location Tracking Energy Efficient Model for Robust Routing over Wireless Sensor Networks

Detecting the location of a mobile sensor node using signal strength has developed an area of dynamic research. The major issue in this situation curtails from the difficulty of how signals spread through space, particularly in the presence of hurdles such as people, walls and buildings. From another perspective, sensors are available with limited power capacity and energy resources. The signal strength guides the node to choose the right node for forwarding the data to the base station. In this paper, we propose a novel location tracking energy efficient (LTEE) model for wireless sensor networks. The presented model in this paper tracks the neighbor node based on the signal strength used for forwarding the data to the next-hop node. LTEE reduces energy consumption and prolongs the network lifetime. The simulation results demonstrated that LTEE consumed 8% to 12.5% less power as compared to other protocols.
