A New Efficient Multi-path Routing Protocol for Mobile Ad hoc Networks
Phu Hung Le · IJARCCE · 2017
A Mobile Ad hoc NETwork (MANET) is a network that does not require any presence of infrastructure.Mobile nodes can move at any time and cannot predict beforehand.Each node acts as a router to communicate with other nodes in the network.The movement of nodes is a big challenge for routing.Another challenge is interference.Interference in the network is one of the most important problems to study.Some interference-aware multi-path protocols were proposed to minimize the impact of interference.However, these protocols are not highly efficient or have a very high computational complexity (NP-hard).In this paper, we propose 1) a definition of interference, 2) a formula of interference and 3) develop a novel Linkdisjoint Interference-Aware Multipath protocol (LIA-MPOLSR) for mobile ad hoc networks.LIA-MPOLSR finds paths only in polynomial time.From our simulation results, we show that LIA-MPOLSR significantly improves performance in terms of packet delivery fraction, end-to-end delay, routing overhead and normalized routing load compared to the prominent protocol Ad hoc On-demand Multipath Distance Vector (AOMDV).
