Issues and Flaws in Endpoint based Call Admission Control for Voice over WLAN

paper presents the various issues and drawbacks of the popular and existing scenario of carrying the Voice over the WLAN . The existing scenario that manages the Voice over Internet Protocol (VoIP), over an IEEE 802.11 WLAN is the Endpoint based Call Admission Control (CAC). Even though the most researches and experiments over the Endpoint based Call Admission Control shows it to the most effective and yielding acceptable QoS, but still there are certain drawbacks and issues that arises in the real time scenario. Therefore, this paper focuses on those areas of this methodology that leads to flaws and various techniques through which issues can be reduced.
