Abstract (in Japanese) (See Japanese page) 
(in English) With advances in wireless communication technologies, people can use multimedia services not only via wired networks but also via wireless networks such as Cellular, WiMAX, and WiFi. On the other hand, however, lack of spectrum resources becomes an important problem for future wireless networks. To overcome this problem, dynamic spectrum sharing method based on genetic algorithm in which a WiFi system temporarily uses a spectrum band of WiMAX system in WiFi/WiMAX integrated network has been proposed. However, this method does not take the handover of users into account. In this paper, we enhance the spectrum sharing method to improve fairness in addition to provide higher throughput considering handover.
Finally we confirm the effectiveness of the proposed method by simulation experiments.
