IEEE 802.11 based Wireless LANs are an important piece in today’s communication infrastructure in order to provide high speed wireless Internet access to static or quasi mobile users. For large WLAN deployments (i.e., Campus or enterprise WLAN), it is important to understand the impact of user mobility and handovers on the system performance. In this article, we have developed a performance model...
Internet connected wireless multi-hop networks are an interesting alternative for providing broadband wireless access. In order for the network to be transparent, the same services need to be available as in standard infrastructure wireless deployments. However, there is a significant challenge in providing services such as authentication, name resolution, VoIP over multi-hop mesh networks as dedicated...
Ad-hoc networks are flexible, self-configurable, easy and fast to deploy. Research has been done mainly in the area of routing and for isolated ad-hoc networks. Some efforts are on the way to connect ad-hoc networks to the Internet. It is however important to support QoS aware multimedia applications in this environment. Therefore, a QoS architecture for ad-hoc networks is necessary that can interwork...
