摘要:
A communication apparatus which is in a wireless network is characterized by comprising a communication means transmitting information among the other communication devices, a means receiving priority order information representing stand-by times different in each communication device from the control station and setting communication devices as control station candidates in a memory, and a means performing communication control as a control station in the wireless network when the stand-by time elapses.

To provide a radio transmission method and a radio transmission apparatus capable of performing a highly-efficient radio transmission depending on the number of communicating stations, a predetermined frame period is prescribed, a management information transmitting field being provided within the frame period, a station sync transmit/receive interval being provided within the management information transmitting field and an arbitrary communicating station being designated to transmit a station sync at plural frame period intervals during the station sync transmit/receive interval. Thus even if only the station sync transmitting area corresponding to the number which is less than the number of communicating stations forming a network exists within one frame, the station sync can be transmitted and received.

An offset value corresponding to the difference between counter values of cycle time counters in two buses is obtained and stored, so that the buses are connected, the value of a first cycle time counter is compensated for buy an offset value. The counter value of the first cycle time counter is compared with the counter value of a second cycle time counter, and a time stamp of data is changed corresponding to the offset value.
摘要:
A wireless transmission apparatus and a wireless transmission method capable of performing simple transmission control, in which an information transmission flow control method, instead of reporting vacant-buffer information from a receiving destination apparatus, an information transmission-source apparatus permits the transmission of a packet up to a predetermined transmission window size from the packet for which acknowledgement has not been received from an information receiving destination, and the transmission of a packet exceeding that transmission window size is inhibited. As a result, if the packet is within that transmission window size, even if the information receiving destination has not confirmed the reception of the acknowledgement (ACK) information, the packet is transmitted unconditionally. Furthermore, a transmission pointer and an ACK receiving pointer are provided, and even if acknowledgement is not received, control is performed using the transmission window size in which transmission is possible.

In order to define and validate a station in a same network easily by specifying a unique network ID in a wireless network system, by using the validation information including the unique network ID in the wireless network system, it is designed to execute, as required, a process of subscribing and connecting to an existing wireless network system in the own station, a process of building up a new wireless network system starting from the own station, a process of transmitting validation information to other station in non-registered state of network ID, as the own station subscribed to the existing wireless network system working as the control station, and a process of removing the station subscribed to the existing wireless network system from the network.
摘要:
Whether a communication is possible among nodes which transmit data in a wireless manner is discriminated and the nodes which can mutually communicate thereamong are set to the same group. In each node, if a node which can communicate with two or more groups exists, the node which can communicate among the groups is set to a bridge connecting the different groups. In case of communicating with the nodes among the different groups, a communication is performed via the node that has been set as a bridge.
