The majority of the routing protocols designed to date for mobile ad hoc networks (MANET) rely on flooding of route requests for the establishment of routes on demand. A novel approach called CBORCA (Cut-Based On-demand Routing with Coordinate Awareness) is introduced. CBORCA improves the efficiency with which route requests are disseminated by partitioning the designated route forwarders in distinct...
We introduce ORTHCA (On-demand Routing with Two Hop Coordinates Awareness) a method for minimizing the dissemination of route requests in mobile ad hoc networks (MANET). The selection of relaying nodes is implemented by first computing the best two-hop relay nodes R2(u) whose Euclidean Distance to four polar points are the shortest among all two-hop neighbors N2(u), and then determining one-hop relay...
Flooding of route requests or link states is a necessity in many routing protocols for mobile ad hoc networks (MANET), and several mechanisms have been devised to make flooding more efficient; however, all flooding approaches to date are such that the number of neighbors each node must use to relay a flooded packet grows as the node density increases. A new method, called ORCA (On-demand Routing with...
The majority of the routing protocols designed and implemented to date for mobile ad hoc networks (MANET) rely on flooding of route requests for the establishment of routes on demand, flooding of topology information, or the hop-by-hop dissemination of distances or paths for each destination. The signaling overhead incurred with these strategies consumes excessive amounts of the scarce bandwidth available...
