Spatial Reuse in Wireless LAN Networks

Dynamic Distributed Authentication Scheme for Wireless LAN-Based Mesh Networks

Wireless LAN systems have been deployed for wireless internet services for hot spots, home, or offices. Recently, WLAN-Based Mesh Networking is developed with the benefit of easy deployment and easy configuration. Due to the characteristic of distributed environment, Wireless Mesh Networks(WMNs) need a new authentication scheme which allows multi-hop communication. In this paper, we propose a d...

Fast Handoff Scheme for Seamless Multimedia Service in Wireless LAN

In this paper , we propose a fast handoff method for seamless multimedia service in IEEE 802.11 WLAN. The proposed method uses an improved access point (AP) with additional radio frequency (RF) module, SNIFFER, monitoring the movement of the station (STA). By using the SNIFFER, the proposed method can completely remove the probe delay. Furthermore, we also propose an effective handoff decision ...

A Motion Detection Scheme For Wireless LAN Stations

Wireless LANs not only provide an effective means of communication, but also allow to detect movement and immobility of a mobile node. This information can, for example, be employed by Wireless LAN positioning systems to reduce the lag of location estimates due to sample filtering. In addition, motion detection has many applications in context-aware computing. This paper proposes a simple schem...

The Spatial Reuse of Wireless Mesh Networks

In this paper, an analysis has been done to determine the spatial reuse of Wireless Mesh Networks. The impact of Common Case and Strong Interference models on the spatial reuse in wireless mesh network has been studied and analyzed extensively. The achievable parallelism with both of the above models has been discussed. It is found that, the transmissions are successful as long as no receiver h...
