Multi-layer Location Verification System in MANETs
The mobility and feasibility of mobile ad hoc networks (MANETs) have to deeply rely on the accurate location information to support multiple applications. A wrong announced location of a node may cause some serious consequences. Thus, the localization and the location security should be considered as important parts of the whole design of the MANETs. In the traditional way, the location verification schemes need complex calculation and multi-step communication with base stations and other vehicles, which are strengthen the burden of the MANETs routings and increased the complexity of protocol. In this paper, an improved multi-layer location verification system (MLVS) based on the optimal common neighbor’s knowledge between claimer and verifier in MANETs is been proposed and discussed. In this system, each node in MANETs could have a trust value, and a mutually shared token scheme is provided to make the decision of the MLVS. Furthermore, the MLVS shows a reliable performance on the ability of attacker defense and accuracy in high node density networks.
