ABSTRACT:
A data transmission method with multiple token mechanism in wireless token ring protocol is provided. First, (a) a logical ring with M nodes is provided; (b) a k-th node is selected from the logical ring, and a token in the k-th node is generated; (c) a first message is sent to a (k+1)-th node from the k-th node with the token, and whether the (k+1)-th node responds a second message is judged, if yes, the data to be transmitted is transmitted from the k-th node, otherwise, the token of the k-th node is eliminated; (d) the token is sent to the (k+1)-th node from the k-th node after completing the transmission of the transmitted data of the k-th node, a generation token sequence is generated in a i-th node, and sent to a (i−1)-th node; and (e) the token is generated for the (i−1)-th node with the generation token sequence.
