Multi-objective Optimization for SDN Based Resource Selection
Nan Bao, Jiakuo Zuo, Haiting Zhu, Xu Bao · 2018
In this paper, a multi-objective optimization resource selection algorithm (MOORS) based on software defined network (SDN) is proposed. The interaction of resource selection strategies is controlled by a multi-objective optimization model. The user's objective is to get the resources with expected quality of service (QoS). While the resource suppliers wants to maximize the rewards with minimum load. A revised algorithm based on reference vector is proposed to solve the model, and compared with other two algorithms. The simulation results show that the proposed algorithm converges to the non-inferior solution set with less fluctuation, meanwhile balances user QoS requirements and network load.
