Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a wireless and power carrier wired hybrid routing method to solve the problem of using the AODVjr algorithm in the prior art, which is suitable for routing networking with a single communication mode in a single node. The "best path" and "shortest path" algorithms adopted by the routing algorithm in the communication mode can only calculate the communication efficiency in one communication mode; therefore, it cannot be applied to technical issues such as the combination of power line carrier communication and RF wireless communication.

Embodiment Construction
[0020] A wireless and electric carrier wired hybrid routing method, which includes:
[0021] Step 1, using the AOVDjr algorithm to establish routing path information;
[0022] Step 1 uses the AOVDjr algorithm to establish routing path information, which includes: route discovery process, reverse route establishment process and forward route establishment process.
[0023] In the route discovery process, for a node with routing capability, when it receives a request to send a data frame from a higher layer of the network layer, and there is no entry corresponding to the destination node in the routing table, it will initiate route discovery process. The source node first creates a routing request packet (RREQ), and uses the multicast (Multi.Broadcast) method to broadcast to surrounding nodes.
[0024] If a node initiates the route discovery process, it should establish the corresponding routing table entry and route discovery table entry, and the state is set to route discove...

The invention discloses a method for selecting a hybrid route of wireless communication and electric power carrier wave wired communication. The method comprises following steps: step 1.establishing route path information by means of the AOVDjr algorithm; 2. selecting a route and calculating the priority of all route paths by a formula; 3. selecting a path which has a maximum priority to a target node and sending data through the path with the maximum priority. The method solves the problems that in the prior art, the AODVjr algorithm is adopted which is suitable for single communication mode route networking of a single node and does not have route selection mechanisms, wherein communication efficiency can only be calculated in one of route algorithms under the signal communication mode adopting the optimal path algorithm and the shortest path algorithm, and therefore the present technology is not suitable for combined usage of electric power carrier wave communication and RF wireless communication.
Description
Technical field: [0001] The invention belongs to the technical field of electric power communication, and in particular relates to a wireless and electric carrier wire hybrid routing selection method. Background technique: [0002] In power line carrier communication and RF wireless communication technology, the routing algorithm based on AODVjr is mainly used. AODVjr routing is an on-demand routing protocol. Only when the routing node receives a network data packet, and the destination address of the network data packet is not in the routing table of the node, the route discovery process will be performed. That is, the content of the routing table is established as needed, and it may only be a part of the overall network topology. [0003] The advantage of AODVjr is that, compared with the AODV routing protocol, it does not need periodic routing information broadcasting, which saves certain network resources and reduces network power consumption. The disadvantage is that ...
