Embodiment Construction
[0038] The following will describe the routing strategy of the present invention in detail with reference to the accompanying drawings and specific implementation methods.
[0039] Such as figure 1 As shown, the present invention adds the identification of this attribute in the message message of AODV routing protocol according to the node motion state (can be learned by using sensors), to indicate whether it is a mobile node or a static node, for different nodes, mutual The strategy of establishing a neighbor (one hop) is different: (1) the strategy of stable neighbor relationship is adopted between the static node and the static node; (2) the strategy of neighbor passive discovery is adopted between the mobile node and the mobile node; (3) the mobile node Between the node and the static node, the strategy of fast switching of the mobile node route is adopted. The operation process of the present invention is described below:
[0040] 1. For type (1) and type (2), see fig...

A stable and efficient adaptive routing strategy for wireless mobile Mesh networks, using sensors to know the node's motion status, and adding a motion status identifier to the message message of the AOVD routing protocol to indicate whether it is a mobile node or a stationary node , and between different nodes, the strategy of adaptively establishing a neighbor relationship (one hop) is different: (1) between a stationary node and a stationary node, a stable neighbor relationship strategy is adopted; (2) between a mobile node and a mobile node Between the neighbors, the passive discovery strategy is adopted; (3) Between the mobile node and the static node, the route fast switching strategy is adopted. The present invention effectively solves the problems of unstable network topology and slow node route switching in the traditional wireless mobile Mesh network, and provides a stable and efficient adaptive routing strategy for the wireless mobile Mesh network, which has important practical significance and great Good application prospects.
Description
technical field [0001] The invention relates to a stable and efficient adaptive routing policy method used in a wireless mobile Mesh network, and belongs to the technical field of routing in a wireless mobile Mesh network. Background technique [0002] Wireless Mobile Mesh Network is an emerging technology to meet people's new needs for wireless networks. Compared with traditional wireless networks, it has higher bandwidth, capacity and speed, and is a distributed network with a wide coverage. The wireless mobile mesh network, also known as wireless mesh network or wireless mesh network, has become a new, efficient and cheap network to realize the next generation of wireless network solutions. In the current wireless mobile Mesh technology, the advantages of other traditional wireless network technologies (such as wifi, 3G, 4G, etc.) are integrated, and the transmission speed is fast. This kind of mesh network can not only greatly expand the coverage of the wireless network...
