所述认知无线电系统包括覆盖重叠区域的多个无线接入系统和同时使用所述一个或多个无线接入系统的认知终端。在本文中，我们描述了一个基于认知无线电系统的负载平衡和吞吐量增强平台的系统架构。在我们的平台中，每个终端可以访问多个无线电系统，使用单个本地IP地址操作。在此基础上，我们开发了仿真器和试验台系统。通过对测试平台系统的仿真和测试，证明了该平台在WiMAX和无线局域网之间实现了系统负载均衡，提高了用户的总吞吐量。此外，负载平衡，以满足实时服务和最佳努力服务。结果表明，该平台能够实现与多个无线系统的融合。
The cognitive radio system consists of multiple wireless access systems that cover overlapping areas and cognitive terminals that use one or more of the wireless access systems simultaneously. In this paper, we describe the system architecture of a platform for load balancing and throughput enhancement with cognitive radio system. In our platform, each terminal, which can access multiple radio systems, operates with a single local IP address. Based on our platform, we have developed both simulator and testbed system. Through the simulation of and the testing of a testbed system, we prove that systems load balance was achieved between WiMAX and wireless LAN, and total user throughput was increased with the proposed platform. Moreover, load balance to satisfy both real time service and best effort service. These results demonstrate the platform described in the paper can achieve a convergence with plural wireless systems.
