Service Response Time of Elastic Data Traffic in Cognitive Radio Networks

Quality of Service (QoS) support over Cognitive Radio Networks (CRNs) is challenging due to the random spectrum availability. Elastic data traffic is a popular service whose service response time is an important QoS parameter. The authors analyze the mean response time of elastic data traffic service operating over a single channel time-slotted centralized CRN under three main service disciplines, Namely, Shortest Processing Time without Preemption (SPTNP), shortest processing time with preemption, and shortest remaining processing time, in comparison with the Processor Sharing (PS) service discipline.
