摘要：

In this paper, we present the analytic and simulation results of the performance of relative location estimation in multi-hop wireless sensor networks. It is found that the location estimation accuracy has a fundamental upper boundary. Location accuracy improves by adding more mobile nodes into the network. However, the resulting accuracy converges towards a fixed asymptotic value that is determined by the total number of links to the reference nodes. It is also established that for multi-hop networks, the location accuracy of a node is highly dependent upon the number of hops it is away from the reference nodes. The further away it is from the reference nodes, the worse the location accuracy.
