Abstract

The availability of interactive multimedia applications (skype, wengo, LiveCom, etc.) is going to modify the usage of future Internet. Such Internet is likely to be more heterogeneous, consisting of different islands of ad-hoc networks. This argues for the growth of interactive applications traffic at the ad-hoc networks level. Providing Quality of Service (QoS) support, in particular low loss rate and low end-to- end delay, in such networks is a challenging task. Limited bandwidth resource and high mobility are two major characteristics of such networks. Moreover, the link breakage rate is high, which leads to high loss rate in the network. In the literature, researches generally span over routing proto- cols and MAC Layer mechanisms [1] to guarantee few QoS aspects by introducing signalling traffic. Wireless Alternative Best Effort (WABE) [2] is an initiative to introduce QoS in ad-hoc networks, without guarantees but only via an alternative to classical Best Effort IP. WABE aims to decrease real-time traffic delay and by the way increase throughput of non-isochrone's traffic: This is achieved without inducing any overhead. In this paper, we consider supporting QoS in ad-hoc networks, with a case study of an application layer multicast. We study how beneficial introducing queuing techniques at the level of ad-hoc nodes routing, could be for a delay-sensitive application running on ad-hoc network. In particular, we demonstrate the effectiveness of WABE on the ad-hoc overlay multicast protocol (AOMP) through simulations.
