Embodiment Construction
[0026] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.
[0027] In this embodiment, the node PHY layer and the MAC layer adopt the wireless Mesh network of the IEEE 802.16d Mesh protocol, and the network layer adopts the improved OLSR protocol (optimized link state routing protocol), that is, the OLSR routing protocol that applies the method of the present invention, specifically Process such as figure 1 .
[0028] After the node is connected to the network, such as figure 1 , the MAC layer of each node in the network periodically or aperiodically exchanges link connectivity information with the MAC layers of surrounding neighbor nodes to obtain MAC-neighbor connectivity information.
[0029]The MAC layer uses the IEEE 802.16d Mesh protocol. There are many signaling interactions when a new node acce...
