发明名称 MULTI-HOP RADIO COMMUNICATION METHOD
摘要 In a multi-hop radio communication network including a base station (a radio station connected to a management server), each radio station in the network is given a data transmission opportunity in turn according to a predetermined transmission order, and transmits data via broadcast or multicast upon occurrence of transmission timing. The radio station having received the data adds data of the radio station to the received data and then forwards the packet via broadcast or multicast when it is the radio station's turn for transmission.

主权项 1. A multi-hop radio communication method comprising: a radio station being any of a radio base station, a radio relay station including a terminal function, and a radio terminal station, one or more of the radio terminal stations, one or more of the relay stations, and one or more of the radio base stations being in a mutually communicable range, wherein data is stored indicating either of predetermined data transmission timing or transmission order defined by a communication timing table in a memory included in each of the radio stations individually, and wherein: (a) when communication data to be transmitted to other one or more of the radio stations are generated in any one of the radio stations of the radio terminal station, radio relay station, and radio base station, a first radio station of the radio stations transmits communication data toward the other one or more of the radio stations via broadcast or multicast, based on or in accordance with the data transmission timing or the transmission order; (b) a second radio station of the radio stations being different from the first radio station and having received the communication data transmits toward the radio station other than the first and second radio stations data to be transmitted prepared by adding transmission data held by the other one or more of the radio stations and data of the station collected by the station to the communication data received; and (c) a third radio station other than the first and second radio stations receives both of the communication data and the data to be transmitted.
