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,twenty-two Working Groups(WGs) mainly define standards for the lowest two layers of the ISO/OSI reference model in the 802.For wireless communication,802WG define 802.11WLAN,802.15WPAN和802.16WMAN.Similar to preceding wireless technologies,data rate slows down by increasing 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 needed.WMNs help to overcome current dependencies of wireless communication systems on wired backbones.Thus,they enable cheap deployment and rapid roll-out for a new generation of wireless services.Summarizes the developing experience of WMN.
