Design and Analysis of Vehicle Tracking Algorithms Based on Wireless Sensor Networks
Wang Yu · Journal of Beijing Jiaotong University · 2008
A vehicle tracking scheme based on wireless sensor networks(WSNs)was designed in this paper.In order to reduce energy dissipation,the method used in this paper minimizes the tracking region and decreases number of active nodes with considering vehicular kinematics.Because the vehicle usually travels with a destination in reality,therefore vehicle's location and velocity are likely to be correlated with its current location and velocity.So the gauss-markov mobility model to predict the vehicle position was introduced,the tracking region was updated by the location of vehicle to keep the mobile target in the tracking region.The simulation results shown that this scheme can reduce energy overhead by 22% compared with OCR.
