Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0046]For the monitoring and control system where the coordinator is used as the aggregation node, the existing tree routing has low efficiency and limited topology; AODVjr routing overhead is large, and because there are many sensor nodes, routing discovery is likely to cause broadcast storms and cause network paralysis; Many-to-one routing needs to maintain the routing table and routing discovery table, and the sink node needs to maintain the routing record table, which is expensive, and the reverse route from the sink node to the sensor node is temporarily stored through the routing record table, which may not be available at a certain time route to a sensor node. In short, due to factors such as overhead, network stability, and reliability, the existing routing methods cannot be well applied to t...

The invention discloses a ZigBee routing method suitable for a wireless monitoring and controlling network, in which a coordinator is used as an aggregation node. Three types of path are available for data transmission from a sensing node to the coordinator. The three types of path are as follows: performing uplink data transmission through an elder node; if the elder node does not exist or a link through the elder node breaks, performing uplink data transmission through a father node; and any node in the network has a path to the coordinator, if the former two paths fail, inquiring a neighbor table to find out any one neighbor node except the elder node and the father node, and transmitting the data to the neighbor node. Data transmission from the coordinator to the sensing node relies on a simple route table, which is established and maintained during transmission of the data to the coordinator, so that the overhead is low and the maintenance is simple. The ZigBee routing method is more targeted for the wireless monitoring and controlling network, and has the characteristics of reliability, low overhead and simple mode.
Description
technical field [0001] The invention relates to the field of wireless sensor networks, more specifically, to a ZigBee routing method suitable for a wireless monitoring and control network in which a coordinator acts as a sink node. Background technique [0002] Facing the advent of the information age, ZigBee wireless sensor network has been applied in many fields with its unique structure and characteristics, such as medical monitoring, environmental monitoring, intelligent meter reading, etc. Such applications are generally a monitoring-based control system, that is, it is necessary to perform corresponding control operations by analyzing the data obtained from monitoring. The sensor nodes in the monitoring area are responsible for collecting relevant information (such as temperature, voltage, etc.), and then pass the collected information to the sink node through the corresponding routing method. In the ZigBee network, the coordinator is generally used as the sink node, a...
