Abstract:
802.11 hardware has ultimately made its way into the electronic consumer market. But, especially in home networks, it clashes with high quality demands of rich multimedia streaming applications, that WirelessLAN can only partly cope with. This work describes basic features and fundamental flaws of 802.11, particularly with regard to multimedia streaming and Quality-of-Service (QoS) requirements. To overcome current problems of missing bandwidth resources in wireless home environments, the presented work points towards future multiinterface extensions of 802.11-based networks, in combination with decentralized Wireless Mesh Network (WMN) structures. The work provides an overview of all relevant 802.11 and WMN components with reference to important research works and indicates basic design aspects, crucial success factors and challenges of a future QoS-ready, multi-layer system that combines the advantages of decentralized wireless networks and of multi-channel MAC usage.
