Call Admission Control Strategy for System Throughput Maximization Using DOVE
In this paper we propose a signal-to-interference (SIR)-based distributed Call Admission Control (CAC) strategy that considers the combined effect of both call and packet level quality of service (QoS) in wireless uplink. Blocking probability and outage probability are considered as call level and packet level QoS parameters respectively. These two QoS parameters are then investigated as functions of relative traffic load. A queuing model based on the delay of voice end-user (DOVE) protocol is used to derive state transition probabilities. The paper deals with the impact of amount of delay of end user on throughput for a particular offered traffic per user. It shows that throughput increases with increase in the amount of delay of end user for a given threshold blocking probability. At the same time, in the underload region, the rate of decrement of the throughput with decrease in the number of channels is less rapid than that of the overload condition. It is the application of DOVE t...
