Abstract
A plurality of nodes each including a transmitter, a receiver, and a controller is linked together via a network. The transmitter of a transmission node using multiple wireless interfaces sends a beacon message sending its own node identifier and wireless interfaces to at least one reception node, which in turn sends back a response message sending its own node identifier and at least one usable wireless interface. The controller of the transmission node determines the broadcast order based on the response message received by the receiver. The transmitter of the transmission node performs broadcasting or multicasting using the wireless interface, which is selected based on the broadcast order. Thus, it is possible to perform broadcasting or multicasting at an efficient usage of radio frequency while covering all reachable neighboring nodes in node-to-node wireless communications based on multiple wireless communication methods.
