Abstract: This paper studied the coverage schuduling problem without the use of node location information.An associa-ted coverage protocol using data correlation(ACPUDC) for WSNs was presented.ACPUDC describes the data redundancy in the networks as formalized data correlation,analyzes the problem of network connectivity,and presentes judgment model of redundant node based on data correlation.The residual-energy-based backoff mechanism in ACPUDC ensures balanced energy consumption of each node.The simulation results verify that ACPUDC can significantly reduce the number of working nodes,and meanwhile,guarantee the QoC and connecivity of networks.Moreover,ACPUDC can make energy comsumption of each node more fair.

Key words: Sensor network,Data correlation,Node scheduling
