This paper is a study of IEEE Standard 802.16 Medium Access Control (MAC) Layer in Distributed Mesh Networks. IEEE Standard 802.16 is a Wireless Metropolitan Area Network (WMAN) technology that can connect different IEEE 802.11 (Wifi) host post with each other and to other parts of internet. It can provide network for a wireless router and at the same time this router can be installed in the office, house or university.WiMAX (Worldwide Interoperability for Microwave Access) is a certification mark for products that pass conformity and interoperability tests for the IEEE 802.16 standards. Products that pass the conformity tests for WiMAX are capable of forming wireless connections between them to permit the carrying of internet packet data. The idea of WiMAX is similar than Wi-Fi but it is not the same. It is a step much higher than Wi-Fi because it is focused to offer internet for a whole city.It has much higher capacity and longer distances. IEEE 802.16 defines a MAC Layer that supports multiple physical layer (PHY) Specifications and different topologies; Point to Multipoint (PMP) and Mesh Networks. In this first topology there exist a Base Station (BS) that have direct links with all ...
