Abstract
A distributed channel allocation method and a wireless mesh network with the same are provided herein. By the distributed channel allocation, interference situations are avoided in a wireless network communication, and the allocated bandwidth can then be fully utilized. Besides, unnecessary depletion of an allocated bandwidth due to the interference can be avoided. By this method, a time division technique is applied for dividing a transmission time of each wireless NIC, and different non-overlapping channels can be assigned to different timeslots. Different from other researches that require a symmetrical number of the NICs between a receiving node and a transmitting node, in this method, a unique wireless NIC may communicate with the wireless NICs. The method provides the feature that the number of the NICs on a certain node can be adjusted to meet a communication requirement, by which the efficiency of a network flow is also significantly improved.
