TDMA FRAME STRUCTURE OF AD-HOC NETWORK AND DYNAMIC TIME SLOT ASSIGNMENT METHOD USING THE SAME

摘要

The present invention relates to a time division multiple access (TDMA) frame structure for avoiding the probability of a collision between nodes on an ad-hoc network and a method for assigning a dynamic time slot to a node using the same. The TDMA frame structure according to the present invention comprises a plurality of repeated subframes which comprise a signaling period composed of control signals for data transmission and a data period for transmitting data, wherein the signaling period comprises: a request mini slot whereby a transmission node to transmit data requests slot allocation; an information mini slot for delivering slot information used by a node in a corresponding subframe and slot information on a 1-hop neighbor node; a suggestion mini slot for suggesting, to a neighbor node, a time slot to be allocated to the transmission node by using the information collected from the information mini slot; and a reply mini slot for replying to time slot allocation suggested by the transmission node in the suggestion mini slot.
