Development of Congestion Control Scheme for Wireless Mobile Network
The tremendous growth of wireless networks demands the need to meet different multimedia (such as voice, audio, video, data, etc) applications available over the network. This application demand and allocation could lead to congestion if the network has to maintain such high resources for the Quality of Service (QoS) requirements of the applications. In this paper, a new admission control policy for wireless mobile multimedia networks is being proposed based on the use of dynamic guard channel allocation scheme. In addition, a buffer will be introduced to store handoff calls if there are no channel available instead of dropping (rejecting) them. The performance analysis of the new scheme will be carried out, especially, the effect of the dynamic threshold and buffer size on call blocking probabilities.
