It is the fact that wireless local area networks are increasingly deployed by businesses, government and SOHO users as they offer many advantages to its customers with mobility, flexibility, convenience etc. It opened a wide range of new commercial areas for hardware vendors, at low cost. This justifies why wireless networks have become one of the most widely used communication systems in the world...
Video multicast over wireless local area networks (WLANs) faces many challenges due to varying channel conditions and limited bandwidth. A promising solution to this problem is the use of packet level forward error correction (FEC) mechanisms. However, the adjustment of the FEC rate is not a trivial issue due to the dynamic wireless environment. This decision becomes more complicated if we consider...
IEEE 802.11 is worldwide implemented being the most widely deployed protocol for wireless local area networks (WLANs). In a realistic environment, WLANs encounter channel fading which causes independent and burst transmission errors which in addition with packet collisions degrade overall performance. In this paper, we present a simple and effective contention window-resetting scheme, named double...
Seamless roaming between cellular networks (3G or upcoming 4G) and wireless local area networks can be provided using Mobile IP. However, GPRS/UMTS and 802.11-based WLAN networks have no native support for mobile IP. Mobile IP requires the deployment of home agents and a protocol between the mobile nodes, home agent, and corresponding nodes. We address the home agent placement and home address assignment...
