Neighboring sensors can collaborate with each other to form a virtual sensor based on cooperative sensing and data fusion, which may increase the length of information barrier. A distributed algorithm DVSF for virtual sensor formation based on non-cooperative games was devised. In order to increase the total length of information barrier of the networks, the DVSF chooses appropriate neighboring sensors to form virtual sensors, and it improves the performance of barrier information coverage of the networks. Simulations of the approach demonstrate the effectiveness and the convergence of DVSF.
