SYSTEM AND METHOD FOR RESERVATION CONFLICT AVOIDANCE AND RESOLUCTION OF TIME SLOTS IN WIRELESS NETWORK

摘要

A method for reserving non-colliding time slots by a node in a wireless network and a method for avoiding colliding time slots are provided. A transmitting node or a receiving node broadcasts information relating to its reserved time slot to neighbor nodes. A node in the wireless network recognizes information relating to time slots of neighbor nodes and of neighbor's neighbor nodes. Thus, when reserving a time slot for data transmission, time slot collision can be prevented by selecting the time slot based on the recognized information. If collision occurs in the reserved time slot and the node wants to cancel the reservation, the node informs a correspondent node of the reservation cancellation. Accordingly, the collision can be promptly resolved.
