Node-Disjoint Alternative Dual-Path Routing for Data Salvation in Mobile Ad hoc Networks

The operational patterns of multifarious backup strategies on AODV-based (Ad-hoc On-Demand Vector) routing protocols are elaborated in this article. To have a broader picture on relevant routing protocols together, variants of AODV-based backup routing protocols are formulated by corresponding algorithms, and also each of them are simulated to obtain the necessary performance metrics for comparisons in terms of packet delivery ratio, average latency delay, and the normalized routing load. Then to make the process of data salvation more efficiently in case of link failure, we explore the possibility of combining the AODV backup routing strategy and on-demand node-disjoint multipath routing protocols. This article proposes an improved approach named DPNR (Dual Paths Node-disjoint Routing) for data salvation, a routing protocol that maintains the only two shortest backup paths in the source and destination nodes. The DPNR scheme can alleviate the redundancy-frames overhead during the process of data salvation by the neighboring intermediate nodes. Our simulation results have demonstrated that DPNR scheme delivers good data delivery performance while restricting the impacts of transmission collision and channel contention. The mathematical rationale for our proposed approach is stated as well.

In [8] NDAMR (Node-Disjoint Alternative Multiple Path) and in [9] DPNR (Dual Path Node-disjoint Routing) are two efficient processes for data salvation in case of link failure. These routing protocols maintain only two shortest backup paths in the source and destination nodes by combining the AODV-BR strategy and on-demand node-disjoint multi-path routing protocols.…”

MANET provides a good platform for any time anywhere networking. Nodes in MANET communicate via wireless multi hop links. Due to frequent node movement routing algorithm in wired network is not suitable for MANET. AODV is the most popular routing algorithm. Route maintenance is the major issue in AODV when there is only one path is established between source and destination. Wireless link breakage is higher in ad-hoc networks due to the node movement, so alternative paths are needed for the route maintenance. This paper gives a new idea to discover multiple node-disjoint routing paths. This extended AODV balances energy and traffic load on whole network to increase the network lifetime. Simulation results show that the performance of proposed Maximum Multipath AODV (MM-AODV) is much better than that of existing AODV.
