An Availability-Based Link QoS Routing for Mobile Ad hoc Networks

With more and more wireless devices being mobile, there is a constant challenge to provide reliable and high quality communication services among these devices. In this paper, we propose an availability-based link QoS (ABLQ) routing protocol for mobile ad hoc networks based on mobility prediction and link quality measurement, in addition to energy consumption analysis. The goal is to provide highly reliable and better communication links with energy-efficiency. The proposed routing algorithm has been verified by NS-2 simulations. The results have shown that ABLQ outperforms existing algorithms by guarantying minimal link breakages and thereby reducing the reconnection and retransmission overhead. It also reduces the average end-to-end delay for data transfer and enhances the lifetime of nodes by making energy-efficient routing decisions.
