Radio communication system, radio communication device, radio communication method

Abstract

It is necessary to solve problems caused when constituting a communication system such as a radio LAN using an independent distributed type network without the controlling-controllable relationship of a master station and a slave station. In the radio communication system consisting of a plurality of communication stations having no relationship of a controlling station and a controllable station, each communication station transmits a beacon describing information on the network, thereby constituting a network. Through this beacon, it is possible to make a sophisticated judgment on the communication state in the other communication station.

Description

technical field [0001] The present invention relates to a wireless LAN (Local Area Network) suitable for configuring a wireless LAN (Local Area Network) in order to realize data communication, for example, constituting a decentralized distributed network without the relationship of a controlling station and a controlled station such as a master station and a slave station. A communication system, a wireless communication device, a wireless communication method and a computer program. [0002] More specifically, the present invention relates to a wireless communication system forming a decentralized distributed wireless network formed when respective communication stations mutually transmit their beacons in which network information etc. are written every predetermined frame period, wireless communication devices A wireless communication method and a computer program, in particular, a wireless communication system, a wireless communication device, a wireless communication metho...

AI Technical Summary

Problems solved by technology

[0032] Question 1: Selection of Coordinator

Although it is desirable to configure the network without a coordinator, the infrastructure model of the IEEE802.11 system cannot meet such requirements

[0034] Problem 2: Inconsistency in reachable range

Thus, there will be a possibility of beacon collisions and ATIM packet collisions, which also leads to a problem

[0037] Question 3: The method to realize the energy saving mode

[0039] Problem 4: Band reservation in networks without a coordinator

[0041] Problem 5: Incompleteness of RTS / CTS procedures

[0043] Question 6: Considerations on the separation of TDMA from BBS

However, according to this method, the space recycling of the resource is aborted, so that the utilization rate is significantly reduced, which also causes a problem
