Abstract

A mobile ad hoc network (MANET) is a dynamically reconfigurable wireless network with no fixed infrastructures. In this paper, we propose a reliable on-demand routing protocol (RORP) with mobility prediction. In this scheme, we determine the duration of time between two connected mobile nodes by using the global positioning system (GPS), and discover a request region between the source node and the destination node for routing discovery. During routing discovery, we can find many routes from the source node to the destination node. Then we select the routing path that requires the longest duration of time for transmission to increase routing reliability. We also propose a GPS-aided partial reconstruction process that selects a backup path for maintenance. When a link on a routing path will break, the route maintenance process is initiated. We use the information from two disconnected mobile nodes to plan a local request region and execute a local route discovery to find a backup path. Simulation results show that the proposed scheme outperforms FORP [27]. lliam, G.
