Abstract:
Provided is a network self-construction method of connecting network devices to a specific network in a wireless application environment in which network devices must be divided into multiple networks in the same space. An access point (AP) controls network association of the network devices by transmitting a beacon signal into which information indicating association permission or non-permission of a network operated by the AP is inserted. A system manager associates the network devices with a specific network through the AP. When the network construction is completed, the system manager disables the AP from permitting additional network association. By repeating these steps, new networks are sequentially constructed. The system manager performs network construction by dividing the network devices into multiple networks in a desired structure and supports additional network association of network devices and transfer to other networks.
Abstract:
A method of signal transmission in the downlink of a multi-hop wireless communication system wherein a coordinator is connected to a plurality of routers and a plurality of end devices through one or more hops and wherein the coordinator and the routers maintain network synchronization by periodically transmitting a beacon signal In the management frame, a control message for system management is transmitted/received, and in the data frame, only devices which are to exchange data transmit and receive data while other devices turn their transceivers off to minimize power consumption.
