“…Our experimental results confirm earlier analytical and simulation-based findings that the AIFSN parameter more effectively protects voice calls against background data traffic than the CWmin [15] [16][17] [18]. The AIFSN differentiation is a superior mechanism to CWmin differentiation because of the existence of discrete instants of times (protected slots represented by the AIFSN difference) where a lower number of stations may compete and access the channel.…”

“…Ongoing work is investigating the use of priority mechanisms supported by standards such as IEEE 802.11e [14], to control the sharing of the handover gains among the involved access points; such control can also increase the number of beneficial scenarios. We plan to study the details of the implementation of the proposed procedure.…”

Abstract. It is well known that in IEEE 802.11 networks, the assignment of low-rate and high-rate users to the same access point significantly degrades the performance of the high-rate users. Our objective is to investigate the implications of the above performance degradation on the incentives for handover between 802.11 wireless local area networks with overlapping coverage. Our focus is on the incentives for supporting handovers, due solely to the improved performance handovers yield for both wireless networks. To study the phenomenon and estimate the potential gain of such handovers, we propose a simple model that predicts the throughput of each access point in different cases. The throughput approximation model can indicate when the handover is expected to be beneficial, and can be used in a handover acceptance policy. Simulation of the proposed procedure suggests that the model is accurate and that there are significant throughput gains for both wireless networks.

This paper presents a new bidirectional transmission protocol with single data frame to computing the performance of MAC layer based on IEEE 802.11n. As high as 600 Mbps of physical data rate is achieved in IEEE 802.11n where high data rate the current MAC layer leads to high performance overhead and low performance of throughput and designing the MAC layer still ongoing to achieve high performance throughput. In this study, a new bidirectional transmission protocol with single data frame has been proposed called BTDF bidirectional transmission data fragmentation, which is divided each data frame from sender to receiver and reverse into subframes and send each subframe, Packets those exceed the size threshold are divided into fragments also where the corrupted subframe will be retransmitted during the disruption of transmission. We have implemented this scheme in NS2 simulator to show the results for TCP and HDTV traffics and compared with literature.
