Resource Joint Allocation Based on Energy Efficiency in Cognitive Collaboration Radio Network

Abstract

Abstract: In the Cognitive Cooperative Radio Network(CCRN),when the secondary users blindly to participate in relay primary users,they will choose the primary users that is not conducive to energy efficiency of the system,thus reduces the overall energy efficiency of secondary user system.To solve the problem,this paper proposes a resource joint allocation scheme.The secondary users have the right to reject the assistance applications that are not conducive to the performance of system,and select primary users who are beneficial to their energy efficiency to assist.In the case of determining the primary user set,through the effective allocation of bandwidth and power,the energy efficiency of the secondary user system is increased.Simulation results show that the scheme can improve the efficiency of secondary system in the condition of ensuring the quality of service for all users.

Key words: Cognitive Cooperative Radio Network(CCRN), energy efficiency, bandwidth allocation, power allocation, resource allocation

摘要： 在认知协作无线电网络中,当次用户盲目地参与到中继主用户中,会选择不利于次用户系统能效的主用户,从而降低次用户系统整体的能效。针对该问题,提出一种资源联合分配方案。次用户有权拒绝不利于自身系统的协助申请,而是选择有利于其系统能效的主用户进行协助。在确定主用户集合的情况下,通过有效地分配带宽和功率来提高次用户系统的能效。仿真结果表明,该方案能够在保证各用户服务质量的情况下,实现次用户系统能效的提高。
