Minimizing Communication Interference for Stable Position-based Routing in Mobile Ad Hoc Networks

For efficient communication in a mobile ad hoc network (MANET) dealing with interference while performing multihop routing is of great importance. By establishing an interference-aware route we can potentially reduce the interference effects in the overall wireless communication, resulting in improved network performance. Typically, mobile devices, represented by nodes in a MANET, are used to broadcast in limited shared media. Therefore, using both routing and scheduling mechanisms for wireless transmissions reduces both redundancy and communication interferences. We study communication interference problems in the context of maintaining stable connection routes between mobile devices in MANETs. In this paper, we extend our previous position-based stable routing protocol (namely, the Greedy based Backup Routing Protocol with Conservative Neighborhood Range) to maintain connection stability while minimizing the number of corrupted packets in the presence of more general communication interference. Simulation results demonstrate the effectiveness of the new protocols.
