Embodiment Construction

[0063] A preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing:

[0064] In the wireless ad hoc network used for the monitoring system, nodes can adopt the routing method of the present invention. The area to be monitored is divided into several sub-districts according to the area or location, and two root nodes are placed in each sub-district (mutual backup), and the root nodes are connected to the background monitoring host through wired or wireless networking. Through this routing method, multiple tree-shaped routes centered on the root node are formed. In practical applications, nodes that rarely move are generally used as root nodes. For individual nodes that move particularly frequently, in order to prevent frequent changes in the routing structure , it can only be used as a terminal node (does not respond to routing requests from other nodes). After the data to be monitored is collected by the nodes, th...

Abstract

The invention relates to a method for routing a queue tree in a wireless self-organization network applicable to a monitoring system. The invention includes a routing generation process, a dynamic maintenance of the routing and a monitoring data amalgamation transmission based on routing arithmetic. A network node selects the neighboring node with a small hot count to send a routing establishment request, and according to a handshaking mechanism, a routing relationship between an upper level and a lower level is established, and the whole network is formed a plurality of tree routing structures; according to ways of a connection detection, a past-due detection and upper node switching, a dynamic maintenance of the routing is realized, changes in network communication topology caused by factors such as the motion of the node and power change are adapted; by using the network structure of the tree routing, the node is able to inosculate the a communication desire to monitor the data in due time at the same time of maintaining the route. The method of the invention has the advantages of low spending on the communication, small delay of transmission and steady and reliable network.

Description

technical field [0001] The invention belongs to the technical field of mobile wireless ad hoc network (MANET), in particular to the networking and routing technology of the wireless ad hoc network used for a monitoring system. Background technique [0002] The wireless ad hoc network is a distributed wireless multi-hop network composed of a group of nodes with routing functions. Nodes can also be pulled into wired networks such as the Internet through wired channels. Because the transmission range of nodes in the ad hoc network is limited, when the source node sends data to the destination node, it usually requires other nodes to provide routing and relay functions. All nodes in the network and the wireless channels between nodes constitute the communication topology of the wireless network. The topology changes brought about by the movement of nodes will cause changes in the communication forwarding path. Therefore, self-organization and dynamic routing algorithms are adapt...
