Embodiment 1

[0030] see Figure 1-3 , an adaptive method for sensor network data transmission, comprising:

[0031] S11, when the MAC layer is in the beacon mode, the network coordinator loads the parameter information field of the current superframe structure into the beacon frame, and broadcasts the beacon frame to all other sensor nodes in the network;

[0032]The execution subject of step S11 is the coordinator. There are multiple sensor nodes under the same network, such as strain sensor nodes, temperature sensor nodes, and acceleration sensor nodes. The coordinator communicates with each sensor node. The strain sensor nodes, temperature sensor nodes , acceleration sensor nodes can upload their respective data to the coordinator. It should be noted that each sensor node transmits data to the coordinator through a superframe structure. Superframe structure such as figure 1 As shown, it is mainly divided into two parts: active and inactive. During periods of inactivity, nodes go to ...

Embodiment 2

[0056] see Figure 4 , an adaptive system for sensor network data transmission, comprising: a coordinator broadcast unit 11, a sensor node request sending unit 12, a priority determination unit 13, a beacon frame modification unit 14, a queue adjustment unit 15, and a data transmission unit 16; The coordinator broadcast unit 11 is used for when the MAC layer is in the beacon mode, the network coordinator loads the parameter information field of the current superframe structure into the beacon frame, and broadcasts the beacon frame to other users in the network All sensor nodes; the sensor node request sending unit 12 is used to send a GTS request frame to the network coordinator if the sensor node needs to use GTS to communicate during the CFP; the priority determination unit 13 is used to The network coordinator determines the priority of the sensor node that has sent the GTS request frame by searching the pre-stated bad grade table, and sorts the sensor nodes according to th...

Abstract

The invention relates to a sensor network data transmission self-adaptive method and a sensor network data transmission self-adaptive system. The sensor network data transmission self-adaptive methodcomprises the steps that: when a MAC layer is in a beacon mode, a coordinator loads a parameter information field of a current superframe structure into a beacon frame, and broadcasts and transmits the beacon frame loaded with the parameter information to all other sensor nodes in a network; if the sensor nodes need to adopt a GTS for communication during a CFP, the sensor nodes transmit GTS request frames to the network coordinator; the coordinator determines priority of the sensor nodes which have transmitted the GTS request frames through looking up a pre-counted severity level table; and the network coordinator allocates content of the beacon frame to the sensor nodes at the top of the priority ranking, and broadcasts the beacon frame to the sensor nodes which open a GTS domain in thebeacon frame. Therefore, data transmitted by means of different sensor nodes can obtain different channel resources, and GTS communication is ensured to be preemptively conducted by events with high severity level or in emergency.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to an adaptive method and system for sensor network data transmission. Background technique [0002] IEEE has formulated the IEEE 802.15.4 standard, which is currently mainly used in Low-Rate Wireless Personal Area Network (Low-Rate Wireless Personal Area Network, LR-WPAN) and Wireless Sensor Network (WSN). The standard defines the corresponding physical layer (PHY) and media access control access layer (MAC) protocol. The MAC layer mainly supports two modes: beacon mode and non-beacon mode, and the superframe structure is allowed to be selectively used in the beacon mode. The format of the superframe is as figure 1 As shown, it is mainly divided into two parts: active and inactive. During periods of inactivity, nodes go to sleep to save energy. The active period consists of three parts: beacon phase, contention access period (Contention Access Period, CAP) and non-com...
