Embodiment Construction

[0133] Preferred embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0134] A. System Configuration

[0135] The communication transmission path assumed in the present invention is wireless, and a network is established between a plurality of communication stations. It is assumed in the present invention that the communication is a storage exchange type of business, and information is transferred in units of packets. Also, in the following description, a single channel is assumed for each communication station, but it is also possible to extend the channel to a channel using a transmission medium composed of a large number of channels, that is, multiple channels.

[0136] The wireless network system according to the present invention has an ad hoc allocation type system structure that does not require a coordinator, and efficiently performs transmission control using channel resources by using a transmission (MAC) frame ...

Abstract

In order to realize low power consumption of a communicator and information transmission in short packets with a short latency in a network environment of a self-organized distribution type, each communication station performs a reception processing before and after a beacon transmission time of a next communication station which transmits a beacon next to a local station, and performs data transmission before and after a beacon transmission time of a communication station functioning as a data transmission destination. In a case where a certain communication station transmits information to all other communication stations, each communication station transmits information by utilizing a reception period provided after the beacon transmission time of the next communication station transmitting the beacon next to the local station to perform transmission according to a bucket-brigade system.
