قرار التسليم الذكي في شبكات SDN بناء على اتجاهات RSSI وهامش التباطؤ

Abstract

This study presents an advanced handover mechanism operating within a Software-Defined Networking (SDN) environment, aimed at facilitating the seamless transition of mobile stations between wireless access points (APs). The proposed mechanism relies on an in-depth analysis of the Received Signal Strength Indicator (RSSI) and hysteresis margin, enabling the system to make intelligent and effective handover decisions. The method integrates RSSI hysteresis margins with trend analysis over time into an adaptive and dynamic scoring system, improving handover decisions and reducing unnecessary handovers, thereby enhancing the overall network stability and performance.

The proposed method was tested in the Mininet-Wifi environment for simulating dynamic wireless networks. The simulation results demonstrated the effectiveness of the method in maintaining stable connections and reducing unnecessary interruptions, ensuring continuous connectivity. Additionally, the ability to dynamically adjust handover parameters by the SDN controller or even by mobile stations in traditional networks increases system flexibility and contributes to performance optimization.
