A Beaconless Minimum Interference Based Routing Protocol to Minimize End-to-End Delay per Packet for Mobile Ad hoc Networks

Abstract

The authors propose a beaconless, on-demand, mobile ad hoc network routing protocol called minimum interference based routing protocol (MIF) that minimizes the end-to-end delay per data packet. During route discovery, each node inserts its identification and location information before broadcasting the Route-Request (RREQ) message in its neighborhood. The weight of a link, called the interference index, is the number of interfering links surrounding it. Two links are said to interfere with each other, if the distance between the mid points of the two links is within the interference range. The interference index of a path is the sum of the interference index values of the constituent links. The destination selects the path with the minimum interference index value and notifies the source through the Route-Reply packet. Simulation results demonstrate that MIF incurs a significant reduction in the end-to-end delay per data packet vis-à-vis the interference-aware load balancing routing protocol.
