Cooperative LBS for Secure Transport System

An increasing number of applications have been developed around a GNSS receiver, such as automotive, marine and spacecraft navigation, surveying and mapping, precise time reference and marketing. A key factor that impacts the application’s effectiveness and performance is the precision and the trust of positioning. The main contribution of this paper is a novel approach for tracking loads using both GNSS positioning capabilities as well as network-supported location services. The use of these two methods allows us to have an independent cooperative evaluation of the current position of the tracked target. To assure the security of the tracking and tracing application we propose a cooperative certification method to evaluate the one-hop distance between the trucked target and all the cooperative nodes in the truck’s view. Since the control center knows the position of every cooperating node, it evaluates a Least Mean Square (LMS) trilateration. This triangulation compared with the position sent by the target allows the control center to make decision on the trucked vehicle. As the results show, the availability of the certification strategy is directly connected to the distribution of the cooperatives nodes. In order to better understand this relationship an analysis has been performed on a scalable network simulator where different mobility scenarios have been considered.
