We propose an integrated location management and location-aided routing system which organizes the Mobile Ad-hoc Network (MANET) into a two-level hierarchy with the help of Voronoi diagrams. The location information of mobile nodes in a Voronoi zone is summarized using Bloom Filters and distributed among the location servers in the zones. The integrated system has the property that the destinat...

Due to the utilization of location information, geographic ad hoc routing presents superiority in scalability compared with traditional topology-based routing in mobile ad hoc networks. However, the consequent solicitation for location presence incurs severe concerns of location privacy, which has not been properly studied. In this paper, we attempt to preserve location privacy based on the ide...

Vehicular ad-hoc network (VANET) is an integral component of intelligent transportation systems. Due to continuous movement of vehicles, network formation and deformation is very frequent. Furthermore, for safety applications, we wish to create the communication without any delay or collision. Therefore, communication among the vehicles is even more challenging. D-LAR (Directional– Location Aid...
