Distributed resource allocation for DS-CDMA based multi-media wireless LANs

With a few exceptions, most of the research dealing with power allocation, and more recently power/rate allocation in DS-CDMA based networks has concentrated on centralized resource allocation algorithms for cellular systems where the base station keeps track of the service requirements and is thus responsible for the management of network resources. Adhoc WLANs, however are configured as peer-to-peer networks with no centralized hub or controller. Thus resource allocation has to be conducted in a distributed fashion. We address the issue of distributed resource management for multi-rate DS-CDMA based multi-media WLANs by presenting a distributed resource allocation protocol that builds on the network allocation vector (NAV) bandwidth reservation scheme provided by IEEE 802.11 and provides quality of service (QoS) guarantees
