Research Of Net Technology Of Low Power Wireless Sensor Network Based On M2M

A characteristic of next generation service is omnipresent. It means expanding the correspondence service object from human beings to any thing, and the communication will exist not only between human and human, human and machine between, but also machine and machine. To support the application of machine-to-machine, we need to give all appliances which execute order confirmation and control function thewireless correspondence function. This article------Research of NetTechnology of Low Power Wireless Sensor Network Based on M2M— —is the research topic which is proposed to manifest the above characteristic precisely. Through the research on the hardware and software knowledge, this article is focused on realizing the low power loss of the overall system on the basis of establishing the system. This research has extremely important practical value especially on the application which needs the battery power supply and long time waits.The MSP430 series monolithic integrated circuit is a kind of 16 bits ultra low power and composite signal processor which TI Corporationpromotes. It aimed at the practical application demand, integrates many analogous circuits, digital circuit and microprocessor on one chip to provide "monolithic" solution. The main characteristics of 430 series monolithic integrated circuits are ultra low power loss, powerful handling ability, high performance simulation technology and rich piece periphery module, convenient highly effective development environment and stable work system and so on.CC1020 is a kind of monolithic UHF transceiver chip which is designed for the extremely low power and extremely low voltage wireless application. It conforms to the EN300 220 and parts of the FCCCFR47 15 standards. It is mainly used in the ISM (industry, scientific research and medical service) frequency band and the SRD of the 426/429/433/868/915MHz frequency band, and it is also used in the multi- channels equipment whose frequency is 424~470MHz and 868~940MHz after programmed CC1020 is especially suited for the narrow band and the frequency-hopping of my system.The wireless correspondence agreement is important problem in a software, it relates to the pitch point performance directly. At present, agreement for the link level and the network level of the wireless sensor network does not have a conclusion, many questions still occupied the research stage of the academic circles. Therefore, this article obtains from the correspondence agreement aspect, designed a wireless sensor networksystem based on the M2M technology. In the link level, I designed a simplification suddenly style correspondence agreement. In the network level agreement, I used the simplification route agreement. In single pitch point, on one hand I use the wireless transmission mode on the hardware, and realized the low power loss;On the other hand the software support frequency-hopping route agreement. Thus make the entire network realize the low power loss performance demand.This article has basically realized the original intention of the systemresearch------follow the major premise of the M2M thought, through theestablishment to the software and hardware, the realization of the wireless sensor network make the current consumption low from the several dozens milliamperes levels to the several hundred microamperes levels with the work condition changing from normal to be able sleep and without sensor.Certainly, the pursuing on low power loss is without limits. This article has only taken some bash research with the existing technical. In the later process of researching and studying, and has only realized a one level network including only the terminal and base station. I shall pursue the higher research aim through more test.
