Executive Summary

An ad-hoc mobile network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. Ad-hoc nodes operating in a single path, single channel model might experience packet loss and high latency due to the congestion caused. Nodes along the heavy traffic path could reach the maximum bandwidth limit and experience undesirable amounts of packet drop. In Ad-hoc networks the nodes are mobile and contain no infrastructure. Certain emergency messages have to be delivered with very low latency and high reliability. An efficient routing protocol should ensure reliable packet delivery in a timely manner. The authors' proposed solution is to setup multiple optimal paths based on bandwidth and delay.
