| Abstract: | The nonuniform node distribution strategy can be used to mitigate the hot spot problem in WSNs.According to theoretical analysis of the nonuniform node distribution,a coverage-preserved node scheduling schemefor sensor networks based on energy prediction in uneven deployment of the network is presented.Simulation results show that the algorithm can prolong the network lifetime,keep higher network coverage rate during the network lifetime and reach the algorithm's designing goal which makes most of nodes in ... |
