Embodiment Construction

[0024] A beacon frame-based wireless sensor dynamic routing networking method may adopt the following steps:

[0025] Step 1.1: All nodes in the network are in the listening state;

[0026] Step 1.2: Receive information and judge information. If the information is a data frame, go to step 1.3; if it is not a data frame, go to step 1.5;

[0027] Step 1.3: Receive information data, and send a data confirmation frame to the next node after the data is received to confirm that the data is received. After merging the data of the current node, judge whether the load is greater than 103 bytes (the maximum load of information in the Zigbee protocol is 103 bytes, and if it is greater than the load, the information will be divided and transmitted). If the load is greater than 103 bytes, go to step 1.4; if the load is less than 103 bytes, forward the data information according to the routing information, and then enter the monitoring state.

[0028] Step 1.4: The current data informat...

Abstract

The invention relates to a wireless sensor dynamic routing networking method based on a beacon frame. The wireless sensor dynamic routing networking method based on a beacon frame is characterized in that a wireless sensor is provided with a unique network address; an aggregation node broadcasts a beacon frame carrying the query information in a flooding mode, wherein the beacon frame includes the address information of the target wireless sensor; after the wireless sensor in the network receives the beacon frame, the wireless sensor determines whether the wireless sensor itself is a target sensor, and if not, the wireless sensor forwards the beacon frame after adding the address information of the wireless sensor, and if so, the wireless sensor stops forwarding the beacon frame; and then the routing is determined through the forwarding path of the beacon frame. The wireless sensor dynamic routing networking method based on a beacon frame forwards the beacon frame through flooding broadcast without excess waste of energy, and as the beacon frame is forwarded only according to the same direction, the blind forwarding phenomenon is not generated. Besides, by means of the flooding broadcast mode, a plurality of routings can be established, thus being convenient for the source node to select different paths to forward the data. The wireless sensor dynamic routing networking method based on a beacon frame is a dynamic routing organization method with lightweight, low energy consumption, high flexibility and high system robustness.

Description

technical field [0001] The invention relates to a networking method of a data exchange network in the digital communication field, in particular to a beacon frame-based wireless sensor dynamic routing networking method. Background technique [0002] The existing typical types of wireless sensor network dynamic routing protocols have their own characteristics, but most of them have the problems of high energy consumption and weak routing dynamic self-organization ability. Generally, an on-demand routing protocol includes three processes: route discovery, route maintenance, and route removal. All three processes will generate energy, and route discovery consumes the most energy. [0003] ZigBee technology is a short-distance, low-speed wireless network technology. Its node equipment has a short working cycle, low power consumption for sending and receiving data information, and uses a sleep mode, which is particularly power-saving; at the same time, because the design of the Z...
