Cooperative Localization and Location Verification in WSN
Localization is one of the most important technologies in wireless sensor networks.A lightweight distributed node localization scheme is proposed by considering WSNs limited computational capacity.The proposed scheme uses the virtual force model to get the location by incremental refinement.Aiming at solving the anchor drifting problem and malicious anchor problem,using sensor node mutual observation principle,a location verification algorithm based on the same computation model as localization process is presented.Extended simulation experiments indicate that the localization algorithm has relatively high precision and the location verification algorithm has relatively high accuracy.The communication overhead of these algorithms is relative low,and the whole set of reliable localization methods are practical.
