Abstract: To make the nodes equally distributing in every subset composed of some sensor nodes in the existing random scheduling algorithm of wireless sensor networks(WSN),a random scheduling algorithm based on the average degree of nodes is presented,which is on the basis of a probability sensing model.Taking advantage of information transmission between the neighbor nodes makes the neighbor nodes of every node distribute in different subsets averagely.The relationship between coverage intensity and the number of nodes is analyzed based on the probability sensing model,which resolves the problem of deploying nodes.Simulation verifies the effectiveness and correctness of the proposed algorithm.
