On Area of Interest Coverage in Surveillance Mobile Sensor Networks

Sensor based surveillance of geographical regions is interesting for applications such as military reconnaissance, environment tracking, and habitat monitoring. For interesting targets to be detected, they must fall within the sensing range of sensors. Static sensors can be used to ensure coverage of whole areas, provided that they have sufficient density and are correctly placed with respect to each other and to the deployment environment. Operating conditions may change, however, which may render the original placement results invalid. To greatly reduce the number of sensors required, and to be robust against dynamic network conditions, mobile sensors can be used to cover given Areas Of Interest (AOI) over time
