摘要： An autonomously dispersed type wireless network is suitably formed with communication stations avoiding collision of beacons transmitted one to another. In the event that the range of reach of airwaves change and a receivable state is created and beacons collide, a communication station changes the beacon transmission position of itself in response to receiving a beacon from another station at a timing immediately prior to transmission to its own beacon. Also, in the event that beacon collision is exposed due to emergence of a new communication which can perform reception from two systems out of airwave range of each other, the newly-participating station requests one of the communication stations of which the beacons are colliding to change the beacon transmission timing.

摘要： Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.

摘要： In order to allow each of communication stations to execute impartial control of accesses to communication media by setting executable-communication ranges of their own independently of each other in a communication environment based on a CSMA method, the present invention provides a radio communication system in which each communication station is capable of checking the occupation state of communication media and setting such an executable-communication range of its own in accordance with the occupation state of the communication media that the number of communication stations coexisting in the executable-communication range is brought to a value within a predetermined range. For example, a specific communication station sets an executable-communication range of its own in order to limit the number of other communication stations capable of communicating with the specific communication station. In addition, a communication station sets an executable-transmission range suitable for an executable-reception range set by itself in order to reduce the degree of non-uniformity of the access control and to minimize the impact of interferences on other communication stations.

摘要： In order to realize low power consumption of a communicator and information transmission in short packets with a short latency in a network environment of a self-organized distribution type, each communication station performs a reception processing before and after a beacon transmission time of a next communication station which transmits a beacon next to a local station, and performs data transmission before and after a beacon transmission time of a communication station functioning as a data transmission destination. In a case where a certain communication station transmits information to all other communication stations, each communication station transmits information by utilizing a reception period provided after the beacon transmission time of the next communication station transmitting the beacon next to the local station to perform transmission according to a bucket-brigade system.

摘要： A wireless communication system includes a first communication station configured to operate according to a first communication protocol, and a second communication station capable of operating according to both the first communication protocol and a second communication protocol. When the second communication station transmits a packet according to the second communication protocol, at least a first signal field compliant with the first communication protocol and a second signal field compliant with the second communication protocol are attached to a header of the packet, and the first signal field includes a parity bit. When the second communication station receives a packet from another communication station, the second communication station performs a parity check on the first signal field of the packet, and when no parity error is detected, the second communication station further checks whether content of the first signal field is compliant with the first communication protocol.
