Abstract

On March 13th 1980, the Computer Society of the Institute of Electronics and Electrical Engineering (IEEE) approved project 802. IEEE 802 is led by the LAN/MAN Standards Committee(LMSC). Until today, 22 Working Groups (WGs) mainly define standards for the lowest two layers of the ISO/OSI reference model in the 802. For wireless communication, 802.11 WG defines the Wireless Local Area Network (WLAN), 802.15 WG defines the Wireless Personal Area Network (WPAN), and 802.16 WG defines the Wireless Metropolitan Area Network (WMAN) standard. With Multiple Input/Multiple Output (MIMO), Ultrawideband (UWB) and sensitive Modulation and Coding Schemes (MCSs), the latest developments in the IEEE 802 standards enable data rates beyond 500Mbps for new applications of wireless communication. Similar to preceding wireless technologies, data rate slows down by increase in distance of the communication entities. However, demands for new applications emerge that need high data rates regardless of distance. To overcome the link speed limitation, dense deployment of wireless networks is needed1. Wireless Mesh Networks (WMNs) help to overcome current dependencies of wireless communication systems on wired backbones by enabling cost-effective and rapid deployment for a new generation of wireless services.
