An efficient geocast algorithm using 2-hop neighbor knowledge in sensor networks

Abstract

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 algorithm should be energy efficient. In this paper we introduce 4 different geocast algorithms using 2-hop neighbor knowledge. We compare their performance using simulation and identify the algorithm with the best performance.
