Target Optimization For Wireless Sensor Networks Coverage Research

As a new form of network, the characteristics of wireless sensor networks,in order to quickly adapt to the network increasingly " everywhere ", and was incorporated into a new pervasive computing. With the rapid development of wireless technology and microelectronics, the theory research of wireless sensor network not only remain on paper; in some practical application direction of many, such as health monitoring, national security, agricultural monitoring, environment monitoring, they have been widely used.The control problem in wireless sensor networks from thetheoretical and methodological, is studied. And an algorithm is put for target coverage optimization. So as to meet the specific quality of service requirements of sensor node coverage at the same time, the network survival time is optimized.The technology of wireless sensor networks, wireless sensor network coverage and key technologies of wireless sensor networks are analyzell. On this basis, this paperanalyzed and studied the classic networks target coveragealgorithm of wireless sensor networks are studied. Then The coverage algorithm is proposed.Some experiments are implemented to verify the improved algorithm.The results showed that:the improved coverage algorithm in execution time and iteration number had better effect, especially considering the coverage problem of its messy degree condition, the results much better.
