The invention discloses a wireless sensor device, a wireless transmitting and receiving device, a wireless sensing network system and method. The wireless sensor device collects a to-be-tested signalthrough the signal acquisition module. When the wireless transmitting and receiving device has a scheduling requirement, a first control instruction of the wireless transceiver is responded in real time through the first wireless network module, and quick response of the wireless sensor device is realized. When a high-speed collected signal to be tested needs to be transmitted to the wireless transmitting and receiving device, the wireless transmitting and receiving device is started. The second wireless network module is switched from the first state to the second state through the first control module. The power consumption of the second wireless network module in the first state is less than the power consumption of the second wireless network module in the second state, and then the second wireless network module transmits the signal to be tested acquired by the signal acquisition module to the wireless transmitting and receiving device, thereby realizing the requirement of high-speed data transmission. Therefore, on the premise that the energy consumption of the wireless sensor is reduced, the scheduling instruction can be quickly responded, and the requirement of high-speed data transmission can be met.

The invention discloses an SDN-based data service transmission optimization method and device, and the method comprises the steps: deploying an SDN controller in a network to achieve the unified planning and scheduling of the network, carrying out the expansion of an openflow protocol, enabling front-end equipment to support the openflow protocol, and obeying the unified scheduling of the SDN controller. The SDN controller monitors the network condition in real time, and when it is found that no redundant network resources are available in the network, the SDN controller coordinates the low-priority video stream service to restrain sending. After receiving the scheduling instruction, the corresponding front-end equipment suppresses the video stream sending of the front-end equipment. Afterthe network resource is recovered, the SDN controller notifies the front-end equipment to recover the related video stream again. Normal sending of high-priority services can be effectively ensured,and network resources are fully utilized.
