摘要： A wireless communication method in a network environment in which several devices are connected and wireless communications are performed through a channel synchronized by a sync signal that is broadcast from a piconet coordinate (PNC) selected among the several devices. The wireless communication method includes classifying a first frame to be transmitted to a first device among the several devices into a predetermined number of classes, calculating a waiting time before backoff depending on the classes, and determining whether the channel is used by any other device during the calculated waiting time, calculating a backoff time according to the classes and performing the backoff during the calculated backoff time, if the channel is idle during the waiting time, and transmitting the first frame when the backoff time ends. By adapting the priority to the CAP of the superframe, the control information is quickly conveyed and a high rate wireless communication is realized.

摘要： A data slot allocation method allowing a plurality of devices in a wireless personal area network (WPAN) to satisfy the required QoS condition for the data stream transmission. The method includes allocating a specific number of data slots of a superframe to the plurality of the devices based on the QoS information; additionally allocating a certain number of data slots to a first device when the first device transmitting a data stream is allocated data slots less than a number of required data slots for the data stream transmission; and reserving the additional data slots for the first device by reducing a number of data slots to be allocated to the other devices, excluding the first device. Accordingly, the data slots can be fairly distributed to the devices.

摘要： A beacon scheduling method in multi-hop ad-hoc communications is provided. This method can prevent overhead in a manner that a base station (BS) transmits beacon slot information to a carrier sense multiple access (CSMA)/collision avoidance (CA) node (CN) and a gateway (GW) through contention-free time division multiple access (TDMA) communications at initial clustering, the CN and the GW performs a sequential clustering to forward the beacon slot information to a cluster head (CH), the CH aggregates joining messages from nodes and assigns non-colliding beacon slots to the nodes, and the GW uses a beacon slot frame of a beacon transmission period (BTP) used by its selected CH in a beacon reply period (BRP) as well. Accordingly, the CH does not need to separately perform the initialization to elect the beacon slot, and the GW also does not require a separate initialization to select the beacon relay slot.
