Improving localization accuracy using signal attenuation due to neighbour signal interference in wireless sensor networks

In wireless sensor networks, estimating location of node is important for routing efficiency and location-based services. Traditional Localization techniques are using by distance, hop-count, connectivity, and etc. But the accuracy of these algorithms is highly dependent on the environment and quality of the transmission equipment and they have not only the localization errors but also high energy consumption caused by packet retransmission. In this paper, we propose a improving localization accuracy algorithm by using a signal attenuation due to neighbour signal interference that is designed to reduce the location error in wireless sensor networks. We compared with The simulation results illustrate our algorithm has improved the communication-cost and accuracy of localization.
