Abstract (in Japanese) (See Japanese page) 
(in English) Wireless channel is characterized with varying nature due to fading, users' mobility and so on. Because the protocol stack is basically “carry-over” from the traditional wired system, the protocols suffer from inability to react to the varying channel condition in wireless networks. In order to mitigate these issues, a large number of cross layer approaches are proposed. However, it is not clear if different cross layer approaches can effectively operate together in the same system. A previous work studied this issue, and concluded that if several cross layer interactions are achieved in an unbridled way, they may lead to unintended adverse interactions, which indeed result in performance degradation and system instability. We believe that in order to achieve efficient wireless communications, cross layer interactions should be performed in a harmonized and optimized way. We have been developing a system to realize harmonized and optimized cross layer interactions. Furthermore, in order to see the effectiveness of harmonized cross layer interactions, an adaptive rate control scheme is implemented in the cross layer system. Empirical results show that the adaptive rate control scheme greatly improves traffic quality.
