Abstract :
Localization is an important problem in wireless sensor networks (WSNs), since location information is widely requested in various location-dependent applications. As one of the range-free localization algorithm DV-Hop, a well known localization algorithm, can be simply implement in real WSNs. To improve the accuracy of localization, this paper proposes an improved DV-Hop algorithm. The proposed algorithm is derived from DV-Hop algorithm, and uses weight of anchors to improve localization accuracy without needing no additional hardware device. Simulation results show that the improved DV-Hop algorithm can provide more accurate location estimation than the DV-Hop algorithm.
