Based On MIMO Network Optimization Model For The Charging Of Wireless Sensor Network

Wireless sensor network as a new generation of network system, because of its small size, the induction ability and self organize into a multi hop wireless communication network, to be able to perceive a specific physical quantity data to the user in the database, and is widely used in military, medical, industrial and environmental protection field. Although the wireless sensor network has a lot of advantages, but the constant supply of energy and how to meet the needs of the growing rate of information transmission, as the development of wireless sensor network block. However, multiple input multiple output technology as a new means of communication, it uses multi antenna structure, in the field of data sending and receiving space to form a plurality of independent parallel communication channels, which can increase the rate of data transmission. Wireless charging technology as a non-contact charging system, can not contact charging equipment, charging of the charging device, as long as the staff specified reasonable cycle charging strategy, continue to work it can guarantee in wireless sensor networks. Provide solutions for problems in the development of these two kinds of technology in wireless sensor networks.The main work of this thesis includes the following aspects:(1) analysis of three kinds of wireless charging technology for Wireless Sensor Networks:the vibration of solar power supply system, and the basic principle and the structure of system and the wave function of the system.(2) analysis of two important communication features of MIMO technology, spatial multiplexing and diversity, MIMO has been able to achieve in improving the transmission frequency of the antenna, can greatly improve the transmission rate of the MIMO parallel channel value. Secondly, introduces how to design in different application environments of MEMO transmission channel modeling and antenna.(3) introduced the characteristics and running environment of LINDO API to solve the mathematical optimization.(4) the analysis on the condition of SISO, how to carry out the continuous optimization model of charging routing optimization and discrete linear model for wireless sensor networks.(5) analysis and put forward in the MIMO wireless transmission technology of the wireless sensor network node, how to design and how to establish the optimization model of charge in the case of MIMO.In the end, the use of LINDO programming software to modeling experiment, ensure the effectiveness of the experiment.
