An Energy Aware Geocast Algorithm Using 2-Hop Neighbour Knowledge in Sensor Networks
Young Chul Shim · International Journal of Computer Science and Information Technology · 2012
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 we introduce a new geocast protocol which minimizes energy usage and overhead by utilizing the knowledge on the neighbours and their energy levels.We evaluate the performance of the proposed protocol with simulation.
