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.

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 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.
