Collision awareness (CA) multiple access networks include the carrier sense multiple access (CSMA), ALOHA, and Ethernet networks. In order to maximize throughput with minimum network delay, these networks employ control parameters such as persistence and backoff. Based upon previous analytic results, the authors derived an asymptotic closed form solution for CA networks. It is demonstrasted that by dynamically changing the persistent value one can ensure that the offered traffic will stay optimal and hence protect the network from over saturation. This technique will greatly enhance the performance of CA networks. Opnet simulation is used to validate the analysis.
