Embodiment Construction

[0033] Such as figure 1 As shown, the present invention adopts the network topology of the MESH network. All devices in the network are full-featured devices, each node can be a coordinator, but only one node can be a coordinator. Each node in the network can talk to each other, so each node can become a relay for adjacent nodes. Therefore, this network form is very flexible, and the routing technology is relatively complicated. Before the device is powered on, the network does not exist, and the information in the routing table of each node is empty; when the device is powered on, the node with routing needs uses an on-demand routing algorithm to determine the network route to the destination node, and Each node saves the generated routing information in the routing table. This kind of network can realize complex functions, and the network capacity is large, without additional relay equipment.

Abstract

The invention discloses an electric power carrier communication routing method. A network node needing routing broadcasts a routing request message to surrounding nodes, each middle node records the address and the routing cost of a next hop in a respective routing table, after the request message arrives at a destination node through a certain path, the destination node selects an optimal path according to different routing costs of different paths, and the destination node initiates a routing response and the routing response can return back a source node through the shortest path. According to the method provided by the invention, a routing cost algorithm in an MESH routing technology is realized. The nodes in a network have a relay function, so that the problem that repeaters are required to be additionally added in a star network architecture is solved. Under the strong support of the MESH network topology structure and each full-function network node, each node in the method further has an ad-hoc networking function, along with the change of environments, the node can flexibly choose routing according to the routing cost among the nodes, and thus, the condition that a path is optimal in any environment at any time can be guaranteed.

Description

technical field [0001] The invention relates to a routing method for power carrier communication. Background technique [0002] The current power line carrier communication mainly has a narrowband single carrier communication mechanism that uses spread spectrum technology to improve the anti-interference and anti-interception capabilities of communication, such as PSK and S-FSK power line communication mechanisms. The network architecture of this method adopts a simple star network structure, and node devices cannot be used as relays, so additional routing relay devices are required. In addition, before the device is powered on, the route has been determined, and the routing information has been stored in the routing table of the node, which cannot be changed flexibly as the environment changes. In this way, each node cannot self-organize a network, but can only form a network according to an existing route, which is greatly limited in the selection of the optimal path. Al...
