Survey of Real-Time Communication in CSMA-Based Networks

Abstract

The purpose of this paper is to survey the state-of-the-art on
real-time (RT) communication in CSMA-based networks and to identify the most suitable approaches to deal with the requirements imposed by next generation communication environments. A special emphasis is given to wired and wireless networks that operate in shared broadcast environments, according to the CSMA medium access
protocol. RT communication solutions are classified according to two classification axes. The first axis is related to how collision are dealt with. A second classification axis is related to the compatibility degree achieved by each of the proposed approaches. Finally, a RT communication framework that is adequate to support RT communication in shared environments is briefly discussed.
