Existing geographic routing algorithms face serious challenges due to location errors, nonplanarity issues and overhead of location service. To solve these issues, we propose Topological Cluster Based Geographic Routing that combines topology-based routing and geographic routing. It is a localized routing scheme where the geographic routing is performed on an overlay network of topological clus...

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...

Abstract Mobile Ad-Hoc Networks are currently experiencing a second youth in terms of research interest as well providing benefits to our society. Clearly, this has been fostered by the wide range applications that have become actually feasible thanks pervasive and increasing presence smartphones, drones, sensors other small devices with communication sensing capability. Aiming deploy solutions...

Recently, geographic routing in wireless networks has gained attention due to several advantages of location information. Location information eliminates the necessity to set up and maintain explicit routes, which reduces communication overhead and routing table size. These advantages allow scalability especially in dynamic and unstable wireless networks. However, no matter which technologies o...
