The fact that distribution uniformity of nodes in wireless sensor networks directly affects node energy consumption determines the life cycle of the whole network. On the basis of uniform design theory,the simulation experiment adopts a series of parameters which include compression discrepancy,sparseness discrepancy,self discrepancy,maximum cavity radius and mini?mum cavity radius to evaluate the nodes distribution uniform performance. The method can measure the distribution uniformity of nodes in wireless sensor networks under the condition that the nodes are deployed randomly. The impact of uniformity on node ener?gy consumption and the life cycle of the entire wireless sensor network are analyzed. The conclusion is drawn that distribution of nodes in wireless sensor network is more uniform,network energy consumption under the conditions of the same coverage is less.
