MULTI-HOP RADIO COMMUNICATION METHOD

摘要

A multi-hop radio network system in which a next-generation power distribution automation network and an AMI backbone network are both used or existent requires distributed P2P communications and hence causes an increase in radio traffic as compared with the centralized-control communication network. Besides, the AMI backbone network requires transmission of data of smart meters which have been concentrated by a concentrator to a management server, and hence causes an increase in the transmission data amount in the vicinity of a communication network base station, with the result that communication delays are disadvantageously increased. 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.
