An Energy Aware Geocast Algorithm Using 2-Hop Neighbour Knowledge in Sensor Networks

Geocast is a mechanism which sends a packet to all the sensor nodes in a certain geographic area. It enables one to collect information from the designated area within a sensor network. Because sensor nodes are operating with limited power source and sending/receiving packets are most energy consuming operations for sensor networks, geocast algorithms should be energy efficient. In this paper, the authors introduce a new geocast protocol which minimizes energy usage and overhead by utilizing the knowledge on the neighbours and their energy levels.
