An improved error localization on DV-Hop scheme for wireless sensors networks

Recently years research on wireless sensor networks (WSN) paid more attention to solve the localization of the wireless sensors, different algorithms had been applied, one of them is DV-Hop, which still need to be improved to obtained better position accuracy. In this paper, we propose a strategy to get accurate location from the unknown sensor using the average hopsize and average error reducing the final localization error. No extra hardware device is required. Simulation shows a better accuracy than the classical DV-Hop.
