Study of call admission control arithmetic on congestion
|
Abstract:
This paper proposed a bandwidth allocation based multi-class admission control scheme (TMSAC).TMSAC rejected all new call when severe congestion occurs; when middle congestion happens,TMSAC rejected the new call if the data transmission of the corresponding service class deteriorates; if no congestion exits,or the congestion was slight,TMSAC decided the call admission based on the limit of the overall throughput and throughput allocation ratios. The results from MATLAB show that the performance of this arit...
