认知无线网络中基于跨层优化的联合资源管理
首发时间:2012-03-08
摘要:本文的研究内容是认知中继系统中支持基于跨层优化的无线资源分配方式 的机制与方法。该方案采集并将各个用户终端的不同业务类型和QoS需求、频谱可用性和信道状况等信息作为无线资源分配决策时的考虑因素,很好的支持了中继与路径选择、频谱分配以及速率控制方案的联合决策,实现了多域无线资源的高效利用。

Cross Layer Based Joint Resource Management in Cognitive Radio Networks
Abstract:In this paper,the scheme for the allocation of wireless resources in cognitive radio networks is discussed,which is based on the cross-layer optimization.The traffic pattern and QoS requirements ,the availability of wireless channels and the corresponding channel state informations are considered comprehensively for the allocation scheme.This scheme supports the joint optimization which including the relay and link selection,channel allocation and rate adaptation,and the high-efficiency for the multi-dimensional wireless resources is achieved.
Keywords: Cognitive Radio Networks Cross layer Design Relay Cooperation
