Simulated Annealing-Based Multilink Selection Algorithm in SDN-Enabled Avionic Networks

In this paper, a novel multilink selection framework is developed for different applications with various quality of service (QoS) requirements in avionic systems, based on the multi-attribute decision-making model. Two metaheuristic algorithms are proposed to solve model while optimizing performances. Multilink configuration and multi-homing capabilities generally required aircrafts operating heterogeneous wireless network environment. The first algorithm, called Analytic Hierarchy Process Simulated Annealing (AHP-SA), utilizes two-phase process. Phase one, an analytic hierarchy process (AHP) used choose decision weight factors. Then, two, simulated annealing applied select suitable networks, requests, weights obtained from phase. Further, improve customer satisfaction, algorithm Simultaneous Weights Network Selection Optimisation (SA-SWNO) developed, which dynamically optimize factors objective functions request-to-network assignment matrix. Simulation results demonstrate that both outperform commonly price-based or QoS-based scheme much higher averaged satisfaction degree lower computational complexity.
