摘要:
针对宽带网络波形(Wideband Networking Waveform,WNW)的多信道二维时频资源,以减小网络资源浪费为优化目标,提出了一种基于定价策略的时隙选择方法(Pricing Strategy Based Slot Selection,PSSS)。该方法通过接纳控制保障资源分配的公平性,采用对偶优化建模与椭圆搜索法实现最优的时隙选择。理论分析证明该方法能够在多项式级别时间复杂度内搜索到时隙选择的最优解。仿真结果表明,提出的PSSS算法通过较低资源浪费获得了较低的容量冗余度,能够有效地解决WNW多信道网络的时隙选择问题。

Abstract:
Considering the two-dimensional time-frequency resource in wideband networking waveform(WNW) with multiple channel,this paper proposes a slot selection algorithm based on pricing strategy called PSSS to minimize the waste of network resource.This method ensures the fairness of resource allocation through admission control and achieves optimal slot selection by using dual optimization formulation and ellipsoid search method.Theoretical analysis proves that this method can obtain the optimal solution under polynomial time complexity.Simulation results show that the proposed PSSS method achieves low capacity redundancy by diminishing resource waste and can effectively solve the slot selection problem in WNW network with multiple channel.
