In order to overcome the problems of high energy consumption and low execution efficiency of traditional Internet of things (IOT) packet loss rate monitoring model, a new packet loss rate monitoring model based on differential evolution algorithm is proposed. The similarity between each data point in the data space of the Internet of things is set as the data gravity. On the basis of the data gravity, combined with the law of gravity in the data space, the gravity of different data is calculated. At the same time, the size of the data gravity is compared, and the data are classified. Through the classification results, the packet loss rate monitoring model of the Internet of things is established. Differential evolution algorithm is used to solve the model to obtain the best monitoring scheme to ensure the security of network data transmission. The experimental results show that the proposed model can effectively reduce the data acquisition overhead and energy consumption, and improve the execution efficiency of the model. The maximum monitoring efficiency is 99.74%.

With the development of computer and biological sciences and information technology, the Internet of things (IOT) technology has been successfully applied to agricultural fields. Twenty-first Centuries is the times that science and technology are rapidly developed. The realization of agricultural modernization and integrated management is the urgently problem needed to be solved for modern agricultural technology. In this background, this paper puts forwards the key technology and existing problems of sunlight greenhouse complex system and intelligent IOT control system through the study of identified collecting and processing process of sunlight greenhouse temperature multi-nodes big system. The paper builds parameters mathematical model for the IOT bearing capacity from four aspects, such as, the occupied bandwidth, delay characteristics of the network, packet loss rate and power consumption, and uses MCU signal amplification system and a signal sensor to jointly control the temperature effect of sunlight greenhouse. Eventually, it finds that the occupied bandwidth of intelligent system has reached 35kb, the highest network delay has reached 20s, and the maximum of packet loss rate has reached 2.5%, which proves that the IOT characteristics of intelligent systems have more controlling complexity than that of the local system.

Background: As more and more renewable energy such as wind energy is connected to the power grid, the static economic dispatch in the past cannot meet its needs, so the dynamic economic dispatch of the power grid is imperative. Methods: Hence, in this paper, we proposed an Improved Differential Evolution algorithm (IDE) based on Differential Evolution algorithm (DE) and Artificial Bee Colony algorithm (ABC). Firstly, establish the dynamic economic dispatch model of wind integrated power system, in which we consider the power balance constraints as well as the generation limits of thermal units and wind farm. The minimum power generation costs are taken as the objectives of the model and the wind speed is considered to obey the Weibull distribution. After sampling from the probability distribution, the wind speed sample is converted into wind power. Secondly, we proposed the IDE algorithm which adds the local search and global search thoughts of ABC algorithm. The algorithm provides more local search opportunities for individuals with better evolution performance according to the thought of artificial bee colony algorithm to reduce the population size and improve the search performance. Results: Finally, simulations are performed by the IEEE-30 bus example containing 6 generations. By comparing the IDE with the other optimization model like ABC, DE, Particle Swarm Optimization (PSO), the experimental results show that obtained optimal objective function value and power loss are smaller than the other algorithms while the time-consuming difference is minor. The validity of the proposed method and model is also demonstrated. Conclusion: The validity of the proposed method and the proposed dispatch model is also demonstrated. The paper also provides a reference for economic dispatch integrated with wind power at the same time.
