Analysing a Consistent Node Disjoint Multipath Routing Protocol for Manets

Abstract

Many link failures are caused in mobile ad-hoc networks due to node’s mobility and exploit undependable wireless channels for data conduction. Due to this, multipath routing protocols become an important research issue. In this paper, we suggest and im-plement a consistent node disjoint multipath routing protocol. The key purpose of the proposed scheme is to determine all available reliable node-disjoint routes from source to destination with minimum routing control overhead. In the route discovery method, the routes with good link quality and route expiration time are selected as the primary and backup routes. If there is any route failure during the data transmission through primary path, the next obtainable backup route with good link quality and route running out time is selected from the list. The performance of the proposed protocol will be evaluated using NS-2 and will be revealed that it re-duces the packet drop and delay there by escalating the packet delivery ratio.
