Equilibrium Point Analysis of the Binary Exponential Backoff Algorithm

Computer Communications, Vol. 24, No. 18, December 2001, pp. 1759-1768.

Abstract: A Markovian model of the backoff algorithm used in the slotted 1-persistent Carrier Sense Multiple Access/Collision Detection (CSMA/CD) access protocol is developed in order to analyze the performance of such a network. Due to its complexity, the existing models of the CSMA/CD protocol do not incorporate the effects of the backoff algorithm. In this work, we developed an approximate Markovian model of the system with a multidimensional state vector and we used the Equilibrium Point Analysis (EPA) technique in order to analyze the model. The throughput – delay characteristics and the stability behavior of the system are extracted, which conform to the simulation results and the predictions of other theoretical models presented in the literature.
