Abstract
A system for data communication in a wireless mesh network that comprises a wired gateway, and a plurality of nodes stationary with respect to each other being disposed in a pattern including at least one path, each of the plurality of nodes located in the at least one path having a transmission range overlapped with that of an immediate adjacent node located in the at least one path, further comprising a node connected to the wired gateway, and an end node located at one end of the at least one path remote from the gateway-connected node, wherein each of a subset of the plurality of nodes, wherein said subset excludes the gateway connected node and the end node, operates in one of a first state in which a first node of the subset is ready to transmit a data frame, a second state at which a second node in the subset is prohibited from transmitting or receiving a data frame and a third state at which a third node in the subset is ready to receive a data frame.
