A Disjoint Alternate Path Routing for Mobile Ad hoc Networks

Abstract

An ad hoc network is a cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure. Developing efficient multi-path routing protocols in an ad hoc environment is a challenging task due to changing network connectivity. In this paper, we have designed a new routing protocol called Node Disjoint Multi-path Ad hoc Routing (NDMA), which gives multiple node disjoint paths between a given source and destination pair. We have analyzed the performance of our protocol by carrying out simulations and compared its performance with existing multi-path protocols such as AOMDV and MDSR. The metrics in our performance analysis are packet delivery ratio, normalized routing load and average end-to-end delay.
