An Incentive Mechanism Based Bi-level Programming Relay Selection Algorithm for Multi-homing Scenario

  • 摘要: 面向泛在无线环境下的多宿主场景,基于多流并发思想探索拥塞小区内高速率业务需求保障问题,该文提出一种基于激励机制的双层规划中继选择算法。首先,建立基于买卖模型的中继激励机制,获得初步成交的中继集合及对应的交易标的值。在此基础上,构建基于双层规划的中继选择模型,以获得最终达成交易的中继集合及对应的交易标的值。借助分类求解策略以快速得到该模型的最优解,从而选择出性价比最佳中继用于协作转发并实现拥塞小区内高速率业务的可靠保障。仿真结果验证了该算法的有益效果。

     

    Abstract: For the multi-homing scenario of ubiquitous wireless environment, a novel incentive mechanism based bi-level programming relay selection algorithm is proposed. According to characteristics of multi-homing scenario, this paper investigates high rate service guarantee problem in congestion cells based on multi-flow parallel access. First, a bargain model based relay incentive mechanism is constructed to obtain the preliminary deal relay set and the corresponding deal results. Second, by using a bi-level programming based relay selection model, the final deal relay set and the corresponding deal results can be obtained. In particular, by means of differentiated solving strategy, the optimal solution of this model can be obtained rapidly, thus selecting cooperation relays with the optimal performance-price ratios and guaranteeing high rate services in congestion cells. Extensive simulations verify the effectiveness of the proposed algorithm.
