Mobile routers are widely used to connect these appliances to the Internet. They have two communication interfaces: one is a terminal for a mobile network, such as 3G, LTE, and WiMAX, and the other is an access point for a wireless LAN. The mobile routers employ power-saving functions for both the mobile network and the wireless LAN. Because each function operates independently, it might be expected that the consumed power could be reduced further through collaborative operation of these two functions. This paper assumes the IEEE802.16m advanced mobile station (AMS) as a terminal of mobile network for mobile routers. In IEEE802.11, the access point (AP) sends buffered packet information to stations (STAs) by means of beacons. Our proposed method exploits this mechanism, and adjusts the traffic indication timing on the IEEE802.16m advanced base station (ABS) side based on the beacon creation time on IEEE802.11 side of the mobile router. Simulation results reveal that power consumption is reduced and delay is reduced except during congestion.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.134 No.4 （2014） 特集：量子ビームによるナノバイオ物理応用技術本誌掲載ページ: 543-549 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/134/4/134_543/_article/-char/ja/ Show more
