基于干扰约束的两阶段频谱拍卖方法
A two-stage spectrum auction scheme based-on interference constraints
摘要
Abstract
To tackle the issues of mutual interference among bidders in spectrum sharing systems and the low spectrum utilization resulting from a fixed interference protection range,a two-stage auction scheme that operates under interference con-straints was proposed.In the first-stage auction,a winner and price determination optimization problem was formulated to maximize the spectrum utility,which is solved by the proposed greedy-policy spectrum auction algorithm.Followed by the second-stage auction,a joint optimization problem for channel allocation and interference protection range flexible adjust-ment was formulated,which is solved by the proposed genetic-based auction algorithm.The convergence of the proposed algorithms was verified by extensive experiments.Furthermore,simulation results demonstrate that the proposed scheme can serve more spectrum users compared to traditional spectrum reuse schemes on the same channels,and potentially im-prove spectrum auction utility and channel reuse rates by approximately 50%in scenarios of scarce spectrum resources.关键词
