Problems solved by technology

Considering the characteristics of wireless networks, in which different devices share and use given wireless resources, increased contention may cause collision during communication, which results in the loss of a large amount of data.
This means that valuable wireless resources may be wasted.
Although these methods may lessen collision and ensure stable communication to some degree when applied to wireless networks, the possibility that collision between transmitted data will occur is still higher than in the case of wired networks.
This is because wireless network environments essentially have a large number of factors adversely affecting stable communication, such as multi-path properties, fading, and interference.
In addition, the more wireless networks that participate, t

Abstract

A method of managing channel allocation for asynchronous data transmission includes (a) broadcasting a first superframe for a first beacon period, the first superframe containing a control section and a data slot section; (b) receiving a request frame from at least one wireless device belonging to a network via the control section, the request frame requesting addition of a data slot for asynchronous data transmission; (c) transmitting a response frame to the at least one wireless device via the control section in response to the request frame; and (d) broadcasting a second superframe for a second beacon period, the second superframe containing information regarding a data slot added to the at least one wireless device.
