摘要:

无线传感器网络拓扑容错性的度量是拓扑容错性研究的基础和前提.考虑到拓扑连通性能与覆盖性能共同反映了网络监测质量,首先依据网络的可用性和有效性,给出了拓扑连通性与覆盖性的度量参数;然后利用网络连通及覆盖的综合服务需求提出了拓扑容错性的新测度——需求容错度;最后以仿真实验验证了该测度对随机、富富、穷穷不同节点失效策略下拓扑容错性的效果差异.结果表明,该测度能准确、有效地测度拓扑容错性的变化.

Abstract:

The metric of topology tolerance in wireless sensor networks is the foundation of the topology tolerance research. Considering that the connectivity and coverage properties can reflect the network monitoring quality, the measuring parameters of the topology connectivity and coverage is proposed according to the usability and validity of the network. A measuring approach of topology tolerance-tolerance demand is provided by using the comprehensive service demand of the network connectivity and coverage. Simulation proves the difference reflection of the topology tolerance with the new measuring approach under different destruction strategy of random, rich-rich and poor-poor. It is shown that the measure can metric the diversification of topology tolerance accurately and effectively.

Key words: wireless sensor networks, topology, tolerant measure, connectivity, coverage
