A Review on Coexistence of WI-FI and WIMAX Using Simulation OF HMM

In the past few years the Wireless local area Network (WLAN) has been the most popular selection of communication among users. WLAN that is based on the IEEE 802.11standard additionally referred to as wireless fidelity (Wi-Fi), offers quality and flexibility with a comparatively low value tousers. Additionally, wireless technology is providing easier web access that is too tough and expensive to reach with ancient wired infrastructure. IEEE 802.16, additionally referred to as Worldwide Interoperability for Microwave Access (WiMAX), is another standard with similar general principles as WIFI with the most blessings being it covers bigger area and contains a higher rate. WLAN and WiMax beneath optimum conditions when compared, the quickest WLAN association is 54 megabits/sec whereas WiMAX is regarding 75Mbit/s. WLAN contains vary of regarding 30 meters and WiMAX will cover up to 50 kilometers. Although WiMAX greatly outperforms Wi-Fi, user devices like desktops, laptops and cell phones got to have WiMAX capability to be able to hook up with WiMAX sources. Currently, not several user devices have WiMAX capability, the majority has Wi-Fi capability. This paper describes the approaches for enabling the coexistence of WiFi and wimax in unlicensed ISM spectrum. We will begin with learning HMM (hidden markov model) supported traces of the network. Then comes the estimation of performance of Wi-Fi in presence of interference from WIMAX. In conclusion we are going to develop unique frame management protocol Known as HMM driven white space aware frame management protocol for coexistence of Wi-Fi and wimax.
