In a large-scale wireless sensor traffic network, collecting and processing of the global real-time traffic information are often unreliable. Making real-time navigation decision becomes an arduous task. To address this issue, an efficient wireless-sensor-network-based real-time vehicle navigation algorithm is proposed, in which multiple local traffic information is considered to make a navigation decision in a quick and accurate way. At the same time, a general distance metric is defined for the processing of both exact and fuzzy data. In addition, the algorithm can provide various navigation decisions according to the choice of different attributes to meet the diverse navigation requirements of drivers. Simulation results show the suitability and efficiency of the proposed algorithm. © 2011 IEEE.
