Embodiment 1
[0062] This embodiment combines figure 1 The network architecture shown is a way to provide AODV routing, such as figure 1 As shown, the wireless Mesh network based on 230MHz is a wireless broadband access technology dedicated to electric power communication. Intelligent advantages such as node self-management and functions such as wireless positioning and timing. The network system is composed of many static wireless nodes and multiple aggregation nodes. The wireless nodes are peer-to-peer, and each node has the functions of data sending and receiving, relaying and routing, and can be configured as a root node as required. The root node accesses the aggregation / backbone network through 230MHz wireless mode, and is responsible for realizing uplink and downlink data interaction with the aggregation node.
[0063] For ease of description, in this embodiment, the wireless nodes are divided into source nodes, destination nodes and intermediate nodes according to the start and e...
Embodiment 2
[0112] In order to facilitate the implementation of the method in Embodiment 1, this embodiment continues to provide an AODV routing node device, which may be the intermediate node in Embodiment 1, or may be a source node or a destination node. Such as Figure 5 As shown, it includes: a receiving module 21 , a calculating module 22 , a determining module 23 and an executing module 24 .
[0113] The receiving module 21 is used to receive the extended RREQ message; the calculation module 22 is used to calculate the penalty weight according to the moving speed of the node device, and accumulate the penalty weight to the penalty weight field in the extended RREQ message; the determination module 23. It is used to determine the optimal path from the source node device to the node device according to the penalty weight accumulated in the penalty weight field; the execution module 24 is used to judge whether the node device is the destination node device. If it is determined that the...
Embodiment 3
[0125] This embodiment provides an AODV routing system, including: a source node and an intermediate node;
[0126] The source node is configured to construct an extended RREQ message when there is no known route to the destination node, and broadcast the extended RREQ message;
[0127] The intermediate node is used for each intermediate node receiving the RREQ message to calculate a penalty weight according to the moving speed of the node, and accumulate the penalty weight to the penalty weight in the extended RREQ message domain and determine the optimal path from the source node to the node according to the penalty weight accumulated in the penalty weight domain; judge whether the node is the destination node, if it is judged that the node is not the destination node, then continue to broadcast the RREQ message.
[0128] The equipment included in the above-mentioned system provided by the embodiment of the present invention is obtained based on the equipment provided in Em...
