Abstract: Based on the characteristics of DV-Distance, an improved algorithm for wireless sensor networks is proposed. The main principle of the improved algorithm is introducing of the straight line/polyline ratio of and the hops between the anchors, reducing the cumulated distance error and location precision error. The simulation results show that the improved algorithm increased the location precision.

Recursive and ad hoc routing based localization in wireless sensor networks
Pinar Kirci,Hakima Chaouchi +1 more
TL;DR: The possibility to use ad hoc routing to help a mobile node in a dense/sparse wireless network to estimate its position is studied by first finding the closest two or three ad hoc reference nodes that are already known their positions then use the position value of the found reference nodes to find the estimated distance.
