摘要：In a dense wireless network where sensor nodes run on batteries it is essential for the continued running ofthe network, to be able to accurately locate and identify nodes that need battery replacement. Accuratelocalization of nodes is also necessary for the correlation of sensed data with position in the environmentcovered by the network. In this paper a new approach to node localization which is fine grained, rangebased,anchor free and GPS free, is presented which is cheap in hardware components and cheap insoftware computation. It concerns the localization of cluster nodes relative to the cluster head and issuitable for cases of stationary or slow moving nodes. The method is demonstrated for a simple one-levelwireless network.
