In this letter, we propose a novel IEEE 802.11 WLAN based MAC to achieve fairness and efficiency for large groups of users. Unlike the current MAC, the proposed scheme excludes nodes which had an access to the channel recently from the contention by controlling a value of CW. The proposed scheme does not only improves throughput performance by reducing contention effectively but also realizes access...
We propose the WLAN/HSDPA interworking architecture that enables us to interwork between HSDPA and WLAN. The WLAN/HSDPA interworking architecture defines the handover-related modules for mobile terminal and the handover switching flows among them. The proposed interworking architecture can be easily extended to support more than two heterogeneous networks. We also provide the experimental results...
