Embodiment Construction

[0042] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0043] The optimized process structure of the present invention is as figure 1 As shown, before the execution of the routing algorithm, the topology update must be completed at the Mac layer, which is an important basis for ensuring the effectiveness of routing; at the same time, because the forwarding nodes in the sending path of the data flow need to send time slots, the routing algorithm of this time frame is as follows: It is the basis of the time slot allocation of each time frame data flow at the Mac layer, which requires that the Mac and the routing algorithm should be co-designed during the low-latency design based on this process.

[0044] Such as figure 2 As shown, the wireless Mesh network periodic cycle scheduling architecture...

Abstract

The invention provides a wireless Mesh network low time delay optimization method based on dynamic time slot distribution. Through changes of a broadcast sequence of nodes in a control frame in an Mac algorithm configuration design, the nodes can timely update time slot demands of the nodes themselves according to path information of data flows, so that forwarding nodes can obtain corresponding time slots when the time slots are distributed. In a time slot competition stage, the path information is added to relevant data by adjusting a time slot application sequence in a network, so time slot demands of network nodes in the time slot competition stage are updated in real time, and the time slot distribution real-time performance for the data flows is improved. Through timely updating of changes of network topology information during a broadcasting period, the nodes can timely sense and update network topology changes. Through processing of key topological data, the cost of a control protocol is reduced, and the data transmission efficiency of the entire network is improved.

Description

technical field [0001] The invention relates to the technical field of wireless mesh Mesh networks, in particular to a low-time-delay optimization method for wireless Mesh networks based on dynamic time slot allocation. Background technique [0002] Wireless Mesh networks generally adopt carrier sense multiple access CSMA random resource scheduling architecture or time division multiple access TDMA resource scheduling architecture. Among them, although the CSMA architecture has strong network scalability, it cannot solve the problem of hidden terminals, and the collision probability increases with the increase of the number of network nodes, so it cannot provide the guarantee of end-to-end delay. The TDMA resource scheduling architecture divides channel resources into multiple time slots according to time for resource scheduling. The protocol design is relatively clear, and the problem of hidden terminals can be solved through the interaction of the control protocol. However...
