Retracted: Target Detection for Wireless Sensor Networks in Smart Grid

Wireless sensor network has been widely applied in advanced measurement system of smart grid. In order to effectively monitor the signal target wireless sensor network, this paper proposes a target location algorithm combined with the cluster routing algorithm and compressed sensing (CS). In this algorithm, the routing algorithm is adopted to cluster the network nodes in the cluster head node for concentrating the information to the cluster head. Multi hop routing is applied for the communication between the cluster head node and sink node in the optimized topology of wireless sensor network. The gradient projection method is used for the data source recovery cluster head and the target signal location. This algorithm can effectively reconstruct the signal and accurately detect the target location, meanwhile, it can effectively reduce the computational complexity. Simulation results are presented to show the effectiveness of the proposed algorithm.
