摘要：

在认知无线通信网络中，多模可重构终端的重构策略对于保证服务质量至关重要．在IEEE 1900.4框架下，提出了一种有效的终端重构策略．该策略将本征向量法与改进的逼近理想解排序法结合起来，可以迅速将终端的可选重构模式依照优先顺序排列，供终端决策;同时，该策略可以为用户提供最佳服务质量．在包含UMTS、WiMAX和无线局域网的认知无线网络中采用该策略进行仿真，结果表明上述策略能够有效地在用户喜好、应用类别以及网络条件之间进行平衡．

Abstract:

The strategy of reconfiguration for a multimode reconfigurable terminal plays an important role in ensuring the quality of service (QoS) in cognitive radio networks. An effective strategy for terminal reconfiguration is presented under the framework of IEEE 1900.4 in this paper. The proposed strategy combines the eigenvector method and the modified TOPSIS (technique for order preference by similarity to ideal solution), which can rank the available reconfiguration mode alternatives with fast and simple implementation. At the same time, it can provide the user with the best available QoS. Simulations are conducted in a cognitive radio network comprised of UMTS, WiMAX and WLANs. The results show that the strategy can effectively decide the optimum mode of reconfiguration by making trade-offs among network conditions, user preference, and service applications.

Key words: cognitive radio networks, terminal reconfiguration, IEEE 1900.4
