Intra-flow Contention Scheme for Improving QoS in WLAN

Simranjeet Kaur, Maninder Singh

Abstract


With the increasing popularity of wireless local area network(WLAN),the demand for multimedia services encompassing VoIP, multimedia streaming and interactive gaming is increasing rapidly. The real-time services require stringent Quality of Service (QoS) guarantees for effective communication. While a lot of research has dealt with providing QoS support for real-time services in traditional wired networks, the shared and broadcast nature of the wireless medium necessitates the design of new solutions for wireless networks. In wireless networks, unlike wired networks, the communication from one node will consume  the bandwidth of the neighboring nodes and hence the  shared  bandwidth  can  be easily over-utilized. Therefore, to  provide  an  acceptable  level  of  QoS  for  the  real-time  services, it  is  necessary   to   control  the   utilization   of   the   shared  bandwidth. In this  paper , we  propose  an  efficient admission control scheme named Intra-flow contention scheme with CAC-OLSR routing protocol for WLAN networks which aims at  preserving  the  QoS  for  all  the  admitted  flows  by employing a low overhead  threshold  mechanism.  We  describe several  alternatives for the design of IAC and compare the performance of these alternatives using  simulation  results.
