Coverage algorithm of mobile wireless video sensor node

The existing wireless sensor networks coverage algorithms are usually for static nodes, and it is unsuitable to measure coverage area by traditional circle models in the wireless sensor networks with video sensors. For that reasons, a coverage algorithm of mobile wireless video sensor nodes and a measurement method for video sensor node coverage area are proposed. Every node also can be kept in an effective distance by using the algorithm, thereby keeping the network connectivity and maximizing the coverage ratio. A simulation model is offered to test the communication efficiency and measure the monitoring area of the algorithm. The result represents that the coverage ratio of the algorithm is about 1. 5 times that of the random algorithm as still keeping the network communication efficiently.
