ROUTING METHOD AND ROUTER SYSTEM FOR WIRELESS NETWORK

摘要

PROBLEM TO BE SOLVED: To improve efficiency in routing on a wireless network and to remarkably shorten a route discovery time. SOLUTION: In a radio station provided with a variable beam antenna 15 capable of selectively switching the omni-pattern of a non-directional radiation pattern and a sector beam pattern which can be scanned by selectively changing a main beam in the form of sector for each prescribed azimuth angle within a horizontal plane with the present station as a center, when an RREQ signal is received from the radio station of a transmitting source while the variable beam antenna 15 is under waiting in the omni-pattern, the variable beam antenna 15 is scanned by a sector beam pattern to detect the arrival azimuth angle information of a sector to become a maximum receiving strength and while using the sector beam pattern of a sector on the back side substantially at 180°to the detected arrival azimuth angle information, the RREQ signal constituted by adding the radio station number of the present station and the arrival azimuth angle information is transmitted. Such processing is repeated until the radio station of a destination receives the RREQ signal. COPYRIGHT: (C)2003,JPO
