With the pervasive use of smart phones in the daily life, location privacy has become one of cruxes for the success of Mobile Social Networks (MSNs). In this paper, the authors propose a Voronoi-Social-spot-aided Location Privacy-preserving (VSLP) packet forwarding protocol to improve the packet forwarding efficiency and at the same time protect receiver's location privacy. In VSLP, they first identify the social spot locations according to the user mobility information, and then build a Voronoi diagram based on the defined social spots. On the edge of Delaunay triangulation over the Voronoi diagram, they deploy multiple storage devices to help receivers to temporarily store the packets. With the security analysis, they show that the location privacy can be achieved.
