Abstract:
1. A method for data communication in a wireless mesh network, comprising: providing a plurality of nodes being stationary with respect to each other; disposing the plurality of nodes 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 immediately adjacent node; performing a first handshake between a first node and a second node in the at least one path, the second node being disposed immediately downstream from the first node; entering the first node into a first state in which the first node is ready to transmit a data frame; entering the second node into a second state in which the second node is ready to receive a data frame; transmitting a first data frame from the first node to the second node; performing a second handshake between the second node and a third node disposed immediately downstream from the second node; switching the first node to a third state in which the first node is prohibited from transmitting or receiving a data frame; switching the second node to the first state; entering the third node into the second state; transmitting a second data frame from the second node to the third node; entering a fourth node disposed immediately upstream from the first node in the at least one path into the third state in response to the first handshake; transmitting an RTR frame from the fourth node to a fifth node disposed immediately upstream the fourth node in the at least one path; entering the fourth node into the second state; and entering the fifth node into the first state.
