performance analysis and comparison between contention-collision cancellation access control mode system models in star network
Contention-Collision Cancellation (C-CC) access control mode is an important access control mode in star network. According to all instances of customer how to contend for service right, how to re-contend for service right after failure, and how to be served after obtaining the service right, C-CC access control mode can be classified into six types of system model. In recent years, people utilize the queuing theory to establish the mathematical models for quantitative evaluation of the six types of system models (see Appl. Math. Model . et al). However, the simulation is still incomplete, especially lack of comparison between these models, so their application field and performance are uncertain. By the simulation under the uniform parameters, this paper makes an overall comparison between six types of models. The research not only completes the comprehensive performance evaluation for the C-CC star network, but also determines the application condition.
