Self-organizing sensor networks: Coverage problem

The problem of coverage in sensor network can be faced in different fields, each having its own special meaning, terminologies and objectives. However, the ultimate goal of solving a `coverage problem' is to blanket a specific `region' with specific `observers'. The region can be planar or volumetric, and the observers can be of limited capabilities. A wireless sensor network is said to provide full coverage in a region if every point in the region is within the monitoring range of some sensors. The main concepts of full coverage will be discussed in this paper.
