Research on Working Vacations Strategy of WLAN MAC Layer

Article Preview

Abstract:

In this paper, we analyze the DCF and PCF schemes, and study some conventional MAC algorithms. For the purpose of satisfying requirements of data transmission in integrated services, a new MAC algorithm based on working vacations is proposed in the paper. Using the continuous system simulation strategy, we design the simulation experiment of MAC algorithm. Combining queuing theory, the steady performance parameters of queuing model is obtained. The results show that the algorithm based on working vacations has an advantage over single PCF or DCF scheme in some indices such as mean queue length, mean delay time and system throughput.
