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...
We describe wireless network utility maximization, WNUM, and compare its performance to traditional NUM along the dimensions of rate, delay and reliability under flat fading. Both coded and uncoded links are considered as are networks with interfering links. In each case, WNUM is shown to offer superior performance in simulations operating under Rayleigh fading due to its ability to adapt to changing...
