How to resolve the problem that multi-user sharing the limitedwireless channel efficiently and reasonably, Namely the design of MAC is one of the key technologies in the mobile Ad-hoc networks. ALOHA and CSMA are the origin of Ad-hoc network MAC protocol, It is important to study them. Mainly introduces the working modes and performance characteristics of ALOHA and CSMA. Has modeled and simulated by using the network simulation software OPNET Aiming at Pure ALOHA and one-persistent CSMA. And comparing the advantages and disadvantages between them. It is instructive to study the new random access protocol.
