Abstract

Wireless ad-hoc networks consist of mobile nodes interconnected by multi-hopwireless paths. Unlike conventional wireless networks, ad-hoc networks haveno fixed network infrastructure or administrative support. Because of thedynamic nature of the network topology and limited bandwidth of wirelesschannels, Quality-of-Service (QoS) provisioning is an inherently complex anddifficult issue. In this paper, we propose a fully distributed and adaptivealgorithm to provide statistical QoS guarantees with respect toaccessibility of services in an ad-hoc network. In this algorithm,we focus on the optimization of a new QoS parameter of interest, serviceefficiency, while keeping protocol overheads to the minimum. To achievethis goal, we theoretically derive the lower and upper bounds of serviceefficiency based on a novel model for group mobility, followed by extensivesimulation results to verify the effectiveness of our algorithm.
