1 2 2 I/F Mobility Anchor Point MAP Composite Wireless Access Networks on Mobile Communications and Its Evaluation Abstract: In emerging wireless communication environments, mobile terminals that have multiple wireless interfaces appear and a diversity of mobile communications is emerging. On the other hand, concern is increasing that the growing use of wireless system will exhaust finite radio resources. Cognitive radio, which aims to optimize the utilization efficiency of radio resources, has been proposed as solution to this problem. Therefore, the wireless access network accommodating a diversity of wireless system will emerge. We assume above wireless access network and propose complex wireless access network consisting of a diversity of wireless system and a method of traffic distribution control. In this paper, assuming mobile communications, we explain a method to control complex wireless access network based on HMIP network architecture. Furthermore, we show its simulation evaluation. 1. 2015 1) 2) 4) 1 Graduate School of Engineering Kansai University 2 Faculty of Environmental and Urban Engineering Kansai University 5) FTP WWW 1
