Applications of Queueing Models in Wireless/Mobile Communication Systems

Communication engineers are always trying to improve the quality of service offered to communication systems users, while at the same time trying to select the system designs that provide the service providers with the maximum profit. Even though quality of service can be described in several forms, including delays, packet loss, error rates, reliability, etc., in the end, a user's perception of quality of the system is measured in delays - delays in getting access to the system, delays resulting from having to re-transmit lost packets, delays resulting from loss of communication and redialling, delays from waiting for an unreliable system to come back up after a failure, etc. The key tools needed in order to assess this performance measure are queueuing models. Modelling of queueing systems, a major branch of Operations Research, is very important in communication systems analysis. In this presentation, we discuss how queueing models have assisted, the communication engineers over the years, and the new challenges posed to queueing analysts as a result of the growth in wireless/mobile communications usage.
