Quality of service in mobile ad hoc networks, carrying multimedia traffic

Abstract

Mobile ad hoc networks (MANETs) have become an integral part of the ubiquitous computing and communication environment, providing new infrastructure for multimedia applications such as video phone, multimedia-on-demand, and others. In order to access multimedia information in a MANET, Quality of Service (QoS) needs to be considered, such as high success rate to access multimedia data, bounded end-to-end delay, security and others. Factors, like delay and jitter, bandwidth and throughput, are studied that affect quality of service in wireless mobile ad hoc networks. Various Quality of Service architectures on IEEE 802.11-based mobile ad hoc networks are discussed, concentrating on architectures that employ cross-layer interaction in the OSI protocol stack. Architectures discussed include IntServ, DiffServ, FQMM, CEQMM, INSIGNIA, SWAN and ASAP.
