GUI based cost effective handoff management in WiMAX Network entry process using key caching mechanism

Mobility management plays an important role in wireless communication networks in effectively delivering services to users on the move. The trouble is the long delay which occurs during the hand off management in these networks. The key caching mechanism is been introduced in this paper which establishes to prevent the un necessary handoff delay, to minimize the authentication cost along with the 50% consumption in the processing time This mechanism is analyzed in mobile Worldwide Interoperability for Microwave Access (WiMAX) in which IEEE 802.1X authentication procedure is used. This mechanism is investigated analytically and the real time process is been simulated through MATLAB GUI model. The time analysis result indicates that the key caching mechanism can effectively speed up the handoff processes.
