| Abstract(in English) | In this paper, we present an exact analysis to numerically evaluate the performance of multiple random access method with non-persistent carrier sense multiple access with collision avoidance (CSMA/CA) protocol for high-speed and realizing fully distributed wireless LANs. The collision avoidance portion of CSMA/CA in this model is performed with a random pulse transmission procedure, in which a user with a packet ready to transmit initially sends some pulse signals with random intervals within a collision avoidatace period before transmitting the packet to verify a clear channel. The system model consists of a finite number of users to efficiently share a common channel. The time axis is slotted, and a time frame has a large number of slots and includes two parts: the collision avoidance period and the packet transmission period. A discrete-time Markov process is used to model the system operation. The number of slots in a frame can be arbitrary, dependent on the chosen lengths of the collision avoidance period and packet transmission period. The influence of possible length of the collision avoidance period and packet transmission period, and pulse transmission probabilities on the network performance is discussed, based on the results of the utilization of channel and average packet delay for the different packet generation rate. |
