Abstract

Sensing coverage is an important issue in wireless mobile sensor networks. The strategy of how to deploy sensor nodes in an environment, especially in unknown large environment, will affect the utility of the network just like the quality of communication. We present an efficient method for sensor deployment assuming that global information is not available. Our algorithm (Self-Deployment by Density Control, SDDC), uses density control by each node to deploy sensor nodes concurrently. We also make nodes to form clusters to achieve area density balance. The characteristics in SDDC are concurrent multi-sensors moving, distributed operation, localized calculation, and self-deployment. Simulations show the good performances compared to the incremental self-deployment algorithm.
