With the process of wireless local area networks (WLANs), the concept of digital home gradually plays an important role nowadays. For this reason, a standard called UPnP, one of the future trends, is proposed. UPnP provides many important functions, for example, active detection, zero-configuration, etc. The problems about the distribution of total bandwidth and QoS become more complicated since multiple...
Nowadays, with the wide establishment of IEEE 802.11, more and more people use Wi-Fi to surf on the Internet. Due to the convenience and mobility of the mobile devices, a number of mobile users have been increasing greatly. For real-time video and VOIP have attracted much attention, the delay time of handoff is the most important issue for the service. In order to provide high-speed service with low...
Recently, with the more extensive deployment of Wireless Local Area Networks (WLAN), and the growing population of mobile users, the unstable handover problem in wireless network services receives more and more attention. Since users expect the continuity of services while roaming, IEEE 802 family defines the standard IEEE 802.11r (Fast BSS Transition) to reduce the interrupted time of services to...
Based on the standardized IEEE 802.11 Distributed Coordination Function (DCF) protocol, this paper proposes a new backoff algorithm, called Smart Exponential-Threshold-Linear (SETL) Backoff Algorithm to enhance the system performance of contention-based wireless networks. As we know, the smaller contention window (CW) will increase the collision probability, but the larger CW will delay the transmission...
