A Distributed Algorithm Based on RSSI for Intelligent Vehicle Localization

Article Preview

Abstract:

Wireless sensor network is added on traditional GPS to realize double location in this paper. The widely used distributed distance measure algorithm of RSSI based in wireless sensor network is adopted. At the beginning work of this position system, unknown position node A broadcast its localization request, after all the base node received this request, they reply node A with its own location info and the RSSI value from other base node. Node A select the most closest base node as base to determine his own location, moreover, distance between base node and signal strength is take as reference to adjust the weight value of every base node, then the precise position is got after final calculation. In the end, precise of this algorithm is proved by simulation experiment.
