An Effective QoS-Based Reliable Route Selecting Scheme for Mobile Ad-Hoc Networks

In mobile ad-hoc networks, the random mobility of nodes will result in unreliable connection. In addition, the bandwidth resource limit will affect the quality of service (QoS) critically. In this paper, an effective QoS-based reliable route selecting scheme (QRRSS) is proposed to alleviate the above problems. The route reliability can be estimated by received signal strength and the control packet overhead can be decreased by selecting more reliable link that satisfies the QoS requirements. Simulation results indicate that the reliable route selecting scheme presented in this paper shows obvious superiority to the traditional ad-hoc QoS on-demand routing (AQOR) in the packet successful delivery rate, the control packet overhead and the average end-to-end delay.
