IEEE 1900.4框架下一种有效的终端重构策略

Abstract

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
