A QoS adaptive source routing protocol for ad hoc communications
H. Labiod, T. Guerniche · 2004
In this paper, we propose a new on-demand QoS-aware routing protocol, named QoS-adaptive source routing protocol (QoS-ASR). QoS-ASR attempts to minimize routing overhead in order to meet multimedia QoS requirements applications. It is an adaptive soft-QoS protocol with aggregate flows that applies the source routing mechanism defined in the dynamic source routing (DSR) unicast protocol. Specially, our protocol is anchored on a new idea based on exploiting application-related constraints (transmission delay, available bandwidth, packet loss rate) as well as ad-hoc network features (battery life, link stability, node congestion state) in order to provide robustness against mobility and wireless channel fluctuations. The performance of the proposed scheme is evaluated via simulations and is compared to DSR.
