Abstract

Traffic control and resource management are complex issues in wireless asynchronous transfer mode (WATM) due to broad range quality-of-services (QoS), limited bandwidth spectrum and susceptibility to error. In WATM, traffic control is essential in order to protect the network from congestion and to achieve realistic network efficiency in compliance with the QoS. Call admission control (CAC) is one of the critical mechanisms in providing QoS. This paper describes bandwidth allocation algorithms for IP traffic over WATM network based on VCT cell cluster threshold. Simulation work using network simulator (NS2) is also carried out to observe the network performance based on the proposed bandwidth allocation.
