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
