Intelligent Control And Management Techniques Of New Energy Illumination Based On Mobile Sensor Network

With the increasing depletion of traditional energy sources, development of new energy industry has become urgent. With its advantages of low power consumption, long life, low power consumption and no pollution. LED (Light emitting diode) has gradually replaced the traditional light source used in lighting systems, as the best choice for saving energy and protecting environment lighting with green energy.Wireless sensor networks combines sensor technology, embedded computing, distributed information technology and wireless communication technology and so has abilities of information perception, transmission and processing capacity. Zigbee is an emerging wireless network technology and has advantages of low power, low cost, high reliability and ease of use. It had been applied in the short-range wireless communication networks occasions more and more widely.With the rapid development of wireless sensor network technology, Cognitive Radio (CR) is proposed to deal with scarce spectrum resources in recent years. It can improve the wireless spectrum utilization, efficiency of data transmission and enhanced anti-interference between the nodes. As a dynamic spectrum management strategy, Cognitive Radio has abilities of spectrum sensing, spectrum analysis, spectrum sentencing and so on. It can also make a real-time reconstruction of the wireless transmission parameters according to the external environment in order to make full use of spectrum hole and not harm to authorized users of spectrum.In this paper, a sensor network establishes as the nodes of solar LED lights system. Each network node adopts zigbee protocol for wireless communication. Data is transmitted multi-hop between nodes in the network. They collaboratively percept, collect and process the information of the perception objects in the network area. It can reduce the transmission power, improve the transmission efficiency and reduce interference with the outside. In order to improve the spectrum utilization and to reduce the interference between the nodes, Cognitive Radio technology is introduced for dynamic management of spectrum in the physical layer, which can avoid complex synchronization and routing algorithms the traditional methods has. This paper focuses on the dynamic spectrum allocation algorithm based on non-cooperative Game Theory and applies it into zigbee sensor network. This paper establishes the model of Game Theory by taking the three spectrum of zigbee protocol as virtual operators and then simulates it. The simulation results show that the Game Theory model which uses the maximum network throughput capacity as the utility function does have the optimal strategy combination and this strategy combination is stable and unique.The multi-hop networks established in this paper has the characteristics of low cost, high spectrum efficiency, interference immunity, stable and easy to use. Therefore it has a certain practicality.
