Abstract

Providing high quality communications service among mobile wireless devices is basically a challenging task in wireless ad hoc networks. In this paper, we propose a Route Stability based Multipath Quality of Service (QoS) Routing (SMQR) protocol for Mobile Ad Hoc Networks (MANETs) to support throughput and delay sensitive real-time applications in MANETs. Reliability of QoS-aware path is improved through the selection of a maximum of three node-disjoint routes with higher stability. With an effective QoS violations detection and route maintenance mechanism followed, the frequency of route recovery and hence QoS disruption is reduced significantly in moderate to highly mobile scenarios. Extensive simulation studies show that SMQR can support higher level of QoS in terms of packet delivery ratio, average end-to-end delay, maximum jitter, and overall network throughput.
