Tehmina Karamat Khan, Taimur Karamat . An Analytical Solution for a Non-Preemptive Handoff Priority-based Cellular Scheme with Drop out Voice and Data Calls. International Journal of Computer Applications. 75, 9 ( August 2013), 12-16. DOI=10.5120/13138-0524
Abstract
The design and engineering of proficient multimedia traffic schemes in wireless cellular networks with Quality of Service (QoS) guarantees involve the performance modeling and analysis of multi-server, finite capacity nodes of queueing network models (QNMs) with drop out calls from queue. This paper focuses on a non-preemptive cellular scheme, where originating and handoff voice and data calls are prioritized by assigning finite capacity queues with dedicated channels, as appropriate. In this context, a performance evaluation study is undertaken based on the analysis of a finite capacity M/M/c/K building block queue with c servers with a Poisson call arrival process and exponentially distributed call time out periods. A new exact closed form steady state probability distribution and associated performance measures are derived and some typical numerical experiments are carried out to evaluate the impact of different traffic patterns on QoS.
