An Estimation Approach for Uniformity of Node-Distribution in Wireless Sensor Networks
Dongfang Wang, Xiaogang Qi · 2009
Whether nodes-distribution is uniformity or not in WSNs(wireless sensor networks, WSNs) has a great influence on the using of nodes' energy and networks' coverage probability, connectivity and life time. Therefore, to estimate uniformity of node distribution in WSNs, we propose several estimation indexes, which are: U-measure index, distance-measure index, area-ration index and clustering index. At the same time, we compare the calculated data of the above indexes for 6 cases of net node distribution. Simulation results show that these indexes can estimate the uniformity of node-distribution in WSNs mostly.
