Executive Summary

Ad-hoc on-demand networks have received a significant interest in the literature. Many routing schemes for such networks focus on finding an optimal path. In this paper, however, the authors consider the routing problem from the viewpoint of sustaining QoS (quality of service) requirement. Some algorithms such as MPDSR already have considered this problem in terms of the end-to-end reliability requirement. While the Multi-Path Dynamic Source Routing (MPDSR) algorithm is capable of resolving the issue to a certain extent, it only considers disjoint paths between a pair of source and destination nodes. In reality due to mobility of nodes there may not exist such disjoint paths.
