Embodiment Construction

[0099] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0100] In the present invention, it is assumed that a communication channel is a wireless channel, and a network is constructed in a plurality of communication stations. Furthermore, it is also assumed in the present invention that communication is a store-and-forward type of service, and that information is transmitted per packet. In addition, although it is assumed in the following description that each communication station has a single channel, the description can also be extended to the case where a transmission medium including a plurality of frequency channels is used, that is, a multi-channel transmission medium.

[0101] In the wireless network according to the present invention, each communication station transmits information directly (randomly) according to an access procedure (Carrier Sense Multiple Access) based on Carrier Sense Mult...

Abstract

Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length) / (rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length) / (rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.

Description

technical field [0001] The present invention relates to a wireless communication system, a wireless communication device, a wireless communication method, and a computer program that perform mutual communication in a plurality of wireless stations such as a wireless local area network (LAN). In particular, the present invention relates to a wireless communication system, a wireless communication device, a wireless communication method, and a computer program in which each communication station is based on a carrier sense multiple access (CSMA) system with collision avoidance. Detection is the basis for performing random access. [0002] More specifically, the present invention relates to a wireless communication system, a wireless communication device, a wireless communication method, and a computer program for realizing random access in a communication environment in which a plurality of communication modes with mutually different transmission rates are mixed. In particular,...
