The Research of Three-Dimensional Coverage Question in Random Deployment Sensor Network

Through researching coverage controlling algorithm which is randomly deployed at three-dimensional space sensor network , a random covering model of the three-dimensional node triangle cone-shape space overlap territory is established. In allusion of the model, a kind of three dimensional covering algorithm is proposed, which both take the node position into consideration and considering the sensation time of neighbor node and the excess energy. The simulation experiment prove that the textual algorithm can solve the three dimensional covering problem of sensor network effectively, reduce the network load and node load and extend the lifetime of sensor network ,adopt the real situation of network deployment much more.
