认知无线电政策推理引擎发展概述

A Survey on Development of the Policy Reasoner in Cognitive Radio

基于政策的频谱管理模式能够对认知无线电进行灵活、细化的频谱管理。政策推理引擎是实现该频谱管理模式的关键。本文概括了频谱管理政策的描述方法,总结了近年来政策推理引擎领域的研究进展,并介绍了基于二叉决策图的政策推理引擎的设计原理。

Policy-based spectrum management can regulate the cognitive radios in a more flexible and detailed way,and policy reasoner plays a key role in the realization of policy-based spectrum management.This paper presented the description of spectrum management policies,generalized the development in research of the policy reasoner in recent years,and introduced the principles in the design of a BDD-based policy reasoner.
