Performance evaluation of a WiMAX mobile network using smart antennas in a simmulated environment

The WiMAX technology is developed for broadband wireless access and it is used in the 4G mobile networks. It offers high data rate services and high flexibility for the radio resource management. Adding smart antenna support and developing new scheduling algorithms for wireless mobile networks based on WiMAX technology it is still a challenge. Such new functionalities will allow better exploiting the WiMAX technology and will make it a solid competitor for the next generation wireless networks. In this paper the performance evaluation of a mobile WiMAX network in the context of smart antennas it is presented. The OPNET simulator was used to implement smart antenna support simulation for mobile WiMAX networks. For performance evaluation, several simulation scenarios were built. The advantage of using smart antennas is illustrated by the simulation results.
