基于QoS保证的多种频谱资源联合分配算法

doi:10.11959/j.issn.1000-0801.2016007

Abstract

Abstract:

The definition of the spectrum availability in terms of static spectrum,semi-static spectrum and dynamic spectrum and the definition of service requirement index based on M-LWDF QoS definition were proposed.A spectrum allocation method and a redistribution method combined with spectrum availability and subscriber requirement were presented.The main idea of the method is that subscriber requirement and availability of spectrum resource are quantified,and then spectrum resources are allocated to subscribers by a one-to-one mapping based on their quantified values in the same sequence.Compared with the random distribution scheme and the dynamic scheme following static allocation,simulation results show that the scheme presented can obviously improve system performance in average number of failure distribution and average total data rate.

Key words: radio spectrum, spectrum availability, spectrum allocation, service requirement, MAX algorithm
