A QoS-aware routing protocol for mitigating end-to-end delay in IEEE 802.11-based mobile ad hoc networks

Providing quality of service (QoS) in a mobile ad hoc network is a challenging task due to its peculiar characteristics. This paper aims at presenting a routing protocol which identifies multiple node-disjoint paths between a given source and a destination. These multiple node-disjoint paths are examined for satisfying QoS in terms of end-to-end delay. In this paper, we analyze the end-to-end delay along the paths taking into account the IEEE 802.11 contention delays. To study the performance of our protocol, we have carried out simulation. The results show that the proposed protocol performs better in terms of QoS satisfaction ratio and the throughput as compared to an existing protocol proposed in the literature.
