Achieving Configurable Location Privacy in Location Based Routing for MANET
Research shows that location based routing can improve the performance and efficiency of communication in mobile ad hoc networks. From another point of view, disclosure of location information can cause a serious privacy risk, especially in environments where different groups of nodes cannot fully trust each other. In this paper, the authors propose a protocol through which a wireless node can achieve configurable location privacy by distributing location information with different levels of perturbations to different groups of nodes. To achieve this goal, polynomial based personal keys are deployed for group based location information access.
