[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0057] In order to overcome the shortcomings of frequent route maintenance and low resource utilization in the existing cross-layer technology, and solve the problem of not distinguishing channel states in the prior art. The channel state-based cross-layer routing optimization method of the wireless Mesh network of the present invention includes MAC layer retransmission control optimization and network layer cross-layer routing optimization, especially wireless network retransmission control and joint routing optimization based on IEEE 802.11 .
[0058] Through dynamic environment perception, adaptive retransmission is performed on data packets that fail to be sent due to conflicts or errors in the MAC layer. By judging the channel state, it can effectively percei...
