In order to reduce the entire network sensor node energy consumption, this text gives an algorithm to track the target effectively and to reduce the energy using the uniform speed and variable speed motion target tracking in Wireless sensor networks as the background. In addition, in order to ensure the accuracy, dynamic members of the cluster nodes using the maximum likelihood to calculate and track the target. Detection radius of sensor node classification to reduce the energy consumption of the entire network. Simulation results show that the algorithm can achieve the accuracy of target tracking and optimize of the network energy consumption. This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text.

Bags of nonwoven fabrics with good air or water permeability are widely used in fruit agriculture due to their porosity. However, vegetables or fruit in bags often rot, a problem caused by the water permeability of the bags in high-moisture environments. Therefore, to improve the water repellency of polypropylene (PP) nonwoven fabric bags for fruit, a water-repellent treatment was applied by the surface deposition of a film composed of a water-repellent agent and a crosslinking agent. The effect of the waterproof bags made of PP spun-bonded nonwoven fabric on the grape growth microenvironment was investigated. This study provided technical inspiration for the development of related plant protection products using nonwoven engineered after-treatments.
