Service Differentiation Using p-Persistent CSMA/CA

Abstract

The problem of service differentiation in wireless LANs is of utmost importance compared to wired networks. Multimedia communication via wireless LANs needs larger bandwidth compared to non-multimedia communications. Hence, a service differentiation scheme to enhance the distinction of service offered to different class priorities is essential. The objective of this thesis is to study the problem of providing service differentiation using proposed p-Persistent CSMA approach and the existing contention window scheme. The areas of this study include service differentiation schemes in p-Persistent CSMAs, various contention window schemes and a number of adaptive service differentiation schemes. Also, a service differentiation rule is used to distinguish the services offered to various classes of traffic.
