Abstract :
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.
