摘要： A wireless mesh network system generates at least one virtual node within a transmission area of a specific mesh node when no mesh nodes exist in two or three continuous quadrants within the transmission area with reference to the specific mesh node. Also, the system performs routing by combining uplink and downlink routing methods so as to support unicast between the mesh nodes in a domain. Further, a channel access order of the mesh nodes is determined based on the potential values allocated to the mesh nodes forming the wireless mesh network according to the field theory. In this instance, the channel access order can be established by a central control method by a central processor for controlling the wireless mesh network or a distributed control method using contention per mesh node.

摘要： The present invention, in preferred aspects, provides a communication method using a network coding packet in a wireless network, with reduced occurrence of negative acknowledgements, between a access point and plural mobile terminals. In preferred embodiments of the present invention, a communication method using a network coding packet in a wireless network comprises: (a) transmitting plural downlink multicast packets, each containing serial numbers of packets, to the first and second mobile terminals sequentially; (b) receiving a first negative acknowledgement from the first mobile terminal; (c) receiving a second negative acknowledgement from the first mobile terminal or the second negative acknowledgement skipping the first negative acknowledgement on occurrence of the first packet error at the second mobile terminal; and (d) transmitting a restoration packet containing exclusive OR packet of all errored packets in the restoration period defined in reference to the second negative acknowledgement from the first and second mobile terminals.
