A coverage algorithm for three-dimensional large-scale sensor network

Energy and bandwidth constraint have been the bottleneck of sensor network applications in years. We work on how to decide the sensor nodes density to guarantee a full coverage and reduce redundancy sensor nodes to reduce energy consumption in a large-scale 3D sensor network. A coverage algorithm using specified 3D network model is proposed and it solves the network sensor density and redundancy problems. The network energy consumption can be significantly reduced by our algorithm.
