Towards Providing Adaptive Quality of Service in Mobile Ad-Hoc Networks
Ronan De Renesse, Vasilis Friderikos, Hamid Aghvami · 2006
Due to the unreliable nature of the wireless medium as well as risks of route failure (mobility), supporting quality of service (QoS) in ad hoc networks is a rather challenging task. In this paper, we propose AQuoS, an exclusive framework which provides and ensures QoS in mobile ad hoc networks (MANETs). Compared to existing work, to our knowledge, AQuoS is the only framework which assume different node capacity limits along with considering multi-hopping and carrier sensing interferences for admission control. To extend our contribution, we also developed a new approach which deals with unexpected lost of QoS guarantees. The low complexity of our scheme along with its flexibility makes it highly scalable for MANETs. Through simulations, we show that AQuoS outperforms SWAN protocol, especially when congestion arises
