Abstract: The WiMAX network designates in common language of a set of standards and techniques of the world of Wireless Metropolitan Area Networks (WMAN). The standard IEEE 802.16 or WiMAX allows the wireless connection of companies or individuals over long distances at high speed. WiMAX provides an appropriate response for some rural or hard-to-reach areas, which today lack access to Broadband Internet for cost reasons. This technology aims to introduce a complementary solution to the Digital Subscriber Line (DSL) and cable networks on the one hand, and to interconnect WiFi hotspots, on the other hand WiMAX is mainly based on a star topology although mesh topology is possible. Communication can be done in Line of Sight (LOS) or not (NLOS).Software Defined Network (SDN) is a new network paradigm used to simplify network management. It reduces the complexity of network technology.The following article aims to expose a simulation implemented under Omnet4.6++, to improve Handover performance and QoS (End-to-end delay, latency, jitter, MoS and lost packet), by implemented an algorithm in SDN controller. The simulation is tested in WIMAX architecture, and results have been collected from two scenarios with and without SDN controller to proof that this algorithm is more preferment to guarantee a better QOS in Handover.
