Zusammenfassung:	To provide a wireless communication system capable of achieving in a short time with low power consumption, rec-connection of a once-disconnected mobile terminal to a wireless communication network.SOLUTION: In a wireless communication system 1 having nodes 3-1, 3-2 for establishing a wireless communication link with an approaching mobile terminal 4; a node for transmitting a beacon before starting wireless communication; and a mobile terminal for establishing a wireless communication link with an originating node of the received beacon. The nodes make frequencies of beacon transmission different from each other chronologically in accordance with chronological locations of the mobile terminals brought closer to or separated from each other.SELECTED DRAWING: Figure 1 【課題】一度離脱した移動端末が無線通信ネットワークに再接続を行うまでに短時間でしかも低消費電力で実現可能な無線通信システムを提供する。【解決手段】近接してきた移動端末４との間で無線通信リンクを確立するノード３－１、３－２を有する無線通信システム１において、無線通信開始前にビーコンを発信するノードと、受信したビーコンの発信元のノードとの間で無線通信リンクを確立する移動端末とを備える。ノードは、近接又は離間する移動端末の時系列的な位置に応じて互いにビーコンの発信頻度を時系列的に異ならせる。【選択図】図１
