摘要: 研究了网络稳定状态下无需节点位置信息的覆盖调度问题,给出了基于数据相关性的关联覆盖协议ACPUDC(Associated Coverage Protocol Using Data Correlation for Wireless Sensor Networks)。它将网络中的数据冗余表示为形式化的数据相关性,并分析了网络连通性问题,给出了基于数据相关性的冗余节点判断准则。协议采用退避机制防止连通漏洞的形成,并采用基于剩余能量的退避机制保证网络的整体能耗分布均衡。通过仿真实验,验证了ACPUDC在保证网络覆盖质量和连通性的前提下,能够显著地减少工作节点的数目,并且使网络整体能量分布均衡,延长网络寿命。

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.
