摘要：Localization is one of the most important tasks for location-aware applications in wireless sensor networks (WSNs). The accuracy of positioning information gives the applications a great number of advantages and, thus, it is very important to choose a localization scheme with the highest accuracy. In this paper, we review three typical localization schemes for WSNs and, then, compare their performance via computer simulation in terms of localization accuracy. The simulation study shows that the probability grid localization scheme achieves the best performance with the minimum location error rate.
