A Path Durability and Delay Based Quality of Service Routing in Mobile Ad hoc Networks

The design of a routing protocol for the provision of quality of service (QoS) in a mobile ad hoc network is a challenging task. In this paper, we propose a QoS routing protocol based on path durability and end-to-end delays. Our protocol tries to identify multiple node-disjoint paths between a given source and a destination. The path selection mechanism employed in our protocol selects paths that are more durable and incur less end-to-end delays. While evaluating performance of the protocol we focus on the following parameters: average number of paths satisfying the QoS requirements, QoS satisfaction ratio, and path failure rate.
