Abstract:

A large number of sensor networks embedded in the real physical world will be three-dimensional （3D）. However, most current sensor network research assumes that sensors are deployed on a two-dimensional plane. This paper focuses on the problem of deployment and organization of sensor nodes in a 3D space. A body-centered cubic structure is proposed for the deterministic deployment of 3D sensor networks. And a sensor node organization strategy for ra3D sensor networks is provided based on the virtual Voronoi cell.

Key words: 3D space, sensor network, deployment, coverage, connectivity
