Objective: In Wireless Mesh Networks the spectrum should be utilized effectively with better Quality of Service (QoS), synchronized time management and minimum delay. Method: The existing channel allocation methods needs improvement in QoS parameters such as end-to-end delay, ripple factor and time factor in accessing the channel. To improve the QoS further, the admission control drop and block probability, efficient channel reservation approach is the better solution which leads to better QoS even for delay sensitive applications. A performance analysis is made among the existing methods for contention reduced channel allocation methods, energy conservation channel allocation methods and as last method Admission Control Drop_Block probability methods. The networks are analyzed by considering the metrics such as Packet loss rate, End-to-end delay and Throughput. The channel count is virtually increased to support for dense networks by utilizing already used channels and by reserving few channels for dynamic requirement for normal and multimedia traffic data. The channel allocation methods are simulated using NS-2.
