Abstract

The optimal deployment of multiple sensor nodes is an important issue in Wireless Sensor Networks (WSNs). Low power, network connectivity and coverage are major performance indicators in the deployment of sensor nodes. However, it is difficult to optimize all of the performance indicators due to trade-off among them. Satisfying user requirements for the deployment of sensor nodes is more important than optimizing the performance in an installation of sensor networks. This paper proposes a novel sensor-node deployment algorithm, which satisfies user requirements such as network lifetime, delay for the sensing data acquisition, and network coverage, using parameters of sensor nodes. Experiments also show that the proposed deployment satisfies the user requirements of sensor networks.
