“…Finally, the purpose of our work is to recover trajectory while the purpose of the VBTC works is to research the driving behavior. What is more, most of the prior works failed to address the following issues: Data missing issue . Considering the fact that mobile terminals are not always power on and there will be fluctuations in the signal transmission performance, data missing can be a very common issue in a VANET.…”

Summary Investigating the mechanisms of various attacks in vehicular ad hoc networks (VANETs) provides fundamental basis to develop safeguard techniques for network security issues. As they develops, attacking strategies are also needed to be established for people to learn how to defend. Previous works failed to consider multiple victims recovery and minimum road side units (RSUs) deployment issues. In this paper, we approach the attacking strategy from an adversarial point of view and develop a trajectory tracking and recovering attack based on matrix completion (TTRA). By randomly sampling locations of vehicles, TTRA is capable of recovering locations of any user with tolerable deviation. After that, the problem of how to minimize the number of RSUs while tracking all vehicles in the whole region is also considered by converting this problem into set covering problem. A heuristic algorithm based on hierarchical clustering is proposed accordingly. To the best of our knowledge, this is the first attempt of recovering mobile users' trajectories by applying these novel techniques. Finally, simulation analysis is used to show the performance of the proposed scheme. Simulation results demonstrate the merits of the scheme in terms of tracking results, location error, and influences of sampling ratio, among others.
