DATA TRANSMISSION METHOD IN LOCAL AREA NETWORK, LOCAL AREA NETWORK AND NODE

摘要

PROBLEM TO BE SOLVED: To provide improved data transmission in a local area network.;SOLUTION: One or a plurality of first nodes, out of a plurality of first nodes, are permitted to use a time slot via competitive access for data transmission in a second interval following a first interval, when a slot possessor node does not start data transmission at a predetermined time within the first interval. A second node determines whether or not the slot possessor node has started data transmission at the end of the first interval. If a determination is made that the slot possessor node has not started data transmission, the second node broadcasts a permission message in a local area network. Each first node is permitted to use a time slot vir competitive access for data transmission, only after receiving the permission message from the second node.;COPYRIGHT: (C)2014,JPO&INPIT
