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. Itenables one to collect information from the designated area within a sensor network. Because sensor nodesare operating with limited power source and sending/receiving packets are most energy consumingoperations for sensor networks, geocast algorithms should be energy efficient. In this paper we introduce anew geocast protocol which minimizes energy usage and overhead by utilizing the knowledge on theneighbours and their energy levels. We evaluate the performance of the proposed protocol with simulation.
