Abstract

Localization of Sensor Node is the basis for the whole of or entire wireless sensor networks. Due to the restricted energy of the sensor nodes, the location error cost of communication and computation should be considered in all the Localization Algorithms. DV-Distance is similar to DV-Hop but with the difference that distance between neighboring nodes are measured using RSSI and is propagated in meters rather than more distances from anchors, then we use Trilateration to calculate their localization. The Algorithm hops, then uses the method similar with distance vector is easy for implementation. But as the with ranging error increasing the localization error is also increases, since this algorithm is still not perfect. In this paper, an improvement of DV-Distance localization algorithm has been proposed.
