An Interference-Aware Multi-Path Routing Protocol for Mobile Ad Hoc Network

Overview & Synopsis

A Mobile Ad hoc NETwork (MANET) is a network without any pre-existing communication infrastructure. Wireless mobile nodes can freely and dynamically self-organize into arbitrary and temporary network topologies. There have been many challenges on the dynamic structure of MANET. One of those is to find the path from a source node to a destination node in the network. In this paper, we propose a formula of interference and a node-disjoint Interference-Aware Multi-Path OLSR routing protocol (IA-MPOLSR) which is based on the Optimized Link State routing protocol (OLSR) for MANET to increase the stability and reliability of the network. From our simulation results, we show that the IA-MPOLSR' packet delivery fraction is remarkably higher than the one of IA-OLSR, the original OLSR and OLSR-feedback. We also show that IA-MPOLSR' normalized routing load is lower than the corresponding results from IA-OLSR, the original OLSR and OLSR-feedback protocols.
