“…The model used to simulate the channel is the Gilber-Eliot [10] 2-state Markov chain model and it is illustrated in figure 11. This model was chosen since it has been found to be a good approximation for wireless channels [11].…”

“…Reference [8] evaluated the performance of different WLANs standards. Reference [9] presented the MPCF to support QoS and evaluated its performance, and Reference [10] gave a performance analysis of popular polling MAC schemes over the Gilbert-Elliot channel model, while Reference [11] proposed OCPM resource allocation scheme to implement a multiservice WLAN. However, some of them can neither differentiate from priority service for the key users, nor guarantee better QoS and system stability.…”

The design of media access control (MAC) protocol that can efficiently support the real-time applications in Wireless Local Area Networks (WLANs) requires that the MAC layer provide strict delay guarantees for sensitive traffic, the Point Coordination Function (PCF) with Round Robin (RR) polling scheme has been included in IEEE 802.11 MAC protocol to achieve this objective. This paper uses two-level-polling scheme to improve the performance of RR scheme, and the closed form expressions for the mean cyclic period (MCP), the mean queue length (MQL) and the mean waiting time (MWT) of the scheme have been obtained, the analytical results are also verified through extensive computer simulations. The comparison results show that the efficiency as well as impartiality of proposed scheme is better than that of the RR scheme.

“…Wireless LAN has got a wide application in different fields with its characteristics such as flexibility usability, extensibility and so on. IEEE802.11 defines that wireless LAN MAC layer has two kinds of medium access mode: distributed coordinating function(DCF) and points coordinating function(PCF) [1][2] .At PCF mode, time is divided into super frames which repeat each other. Super frame contains two stages: CFP and CP.…”

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.
