Delay analysis of a slotted ring medium access protocol

Abstract

An approximate delay analysis of a slotted ring medium access protocol is represented. The operation is based on a continuous stream of slots circulating around the ring. The delay model is represented. Assuming that a slot is reserved with a preassumed probability, an expression for the z-transform of the number waiting in the queue is derived by using the embedded technique. From this the expression for the average access delay is obtained. The approximation of the probability is then found and the average delay can be solved. The incoming traffic is assumed to be Poisson. Numerical results are discussed.<>
