Embodiment Construction

[0047]The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0048] As shown in Figure 1, the data collection area is set to install a set of collectors and repeaters every three floors, and each node is connected to the background monitoring host through a wireless network. In practical applications, the collector repeater is generally installed in the collector of the electric meter and placed at the access control of the community building, and the common nodes are placed in the corridors and residents' homes according to the location of the meter.

[0049] As shown in Figure 2 and Figure 3, the specific steps of route establishment are:

[0050] Carry out address coding and initial routing feature codes for each node, and set the period of the routing initiation interval and the listening limit time for the root node. The address code of a node consists of two parts: the cell code and the node num...

Abstract

The invention discloses a clustering Ad hoc network routing establishment method for three-meter wireless centralized reading. A class cluster model using an electrically powered collector and a battery powered relay as cluster heads is established to realize the networking of gas meters in a building. The method comprises two processes of routing establishment and routing maintenance. In the routing establishment process, in view of the actual condition of the collector away from the battery powered relay that needs to be installed to assist the collection, and in order to ensure effective resource utilization, the class cluster model is designed and realized in a ''barrel''-shaped building depending on the distribution of housing estates and by considering a reliable collection distance between the collector and the relay, and balanced energy classification is realized by considering node energy and link energy. In the routing maintenance process, in the case of a fault of the cluster head or the auxiliary cluster head in a link, node error information is sent, and for the invalid node, networking is carried out with the surrounding cluster heads in the most energy-saving mode again so as to ensure the reliable and efficient transmission of data.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a method for establishing a clustered ad hoc network routing for wireless centralized reading of three meters (electricity meters, water meters, and gas meters). Background technique [0002] The wireless ad hoc network is a distributed wireless multi-hop network composed of a group of nodes with routing functions. Due to the limited transmission range of other nodes, other nodes are usually required to provide routing and relay functions when the source node sends data to the destination node. All nodes in the network and the wireless channels between nodes constitute the communication topology of the network. The topology changes brought about by the addition and deletion of nodes will cause changes in the communication forwarding path. Therefore, wireless ad hoc networks need to use dynamic routing algorithms to adapt to changes in topology and adjust routing. [0003] Ad...
