Wireless sensor network system and method for processing data
Technical Field The invention relates to a support in the network data storage, management and excavation, transparent and non-transparent upgrade of the software and multi-language programming of the wireless sensor network to realize the system and method of the above-mentioned tasks, which belongs to the wireless self-organizing network system technical field Background Art Wireless sensor network (Wireless Networks Sensor, abbrebyted WSN) is a wireless network as a means of communication Ad-Hoc, collection, treatment and analysis with sensing capability in the network node for the purpose of obtaining the data of the large-scale self-organizing network. See Figure 1, this method is based on the heterogeneous wireless sensor network, the system has a plurality of different size (and micaz TFAD-901) sensor node, data aggregation node, program server and customer end. Between each node node of the sensor and the data collection node, program server between the communication in a wireless mode, the data collection server and a user end of the between the wired or wireless mode communication. Sensor network for data acquisition, management, excavation, the upgrade of the software in the research work in such areas as at home and abroad have a certain research foundation has been, made many theoretical problems, and to achieve some utility middleware system of the based on most of these middleware system Mica series of hardware node TinyOS and. Literature and in the wireless sensor applications projects Impala ZebraNet and its middleware system. ZebraNet is the research projects of wild animals. Based on event-based middleware system Impala modular programming model is easy to program staging, fault-tolerant and energy-saving. However, the support of the data management Imapala very few, and can only in homogeneous operation under the environment. Mate system is to construct the TinyOS system the virtual machine, hiding the details of the underlying operating system. Although Mate simple model has the advantages of small volume, simple programming model, but energy consumption is great and cannot support large-scale application. Agilla is realized on the 1st TinyOS mobile proxy middleware. Agilla as a mobile proxy middleware allows the agent to move from one node to another node, and a node can be operated at the same time a plurality of agents can be in the sensor network at the same time the application program different operation. Agilla and is not authorized, however, monitor the agent mechanism, and the maintainability of the unsatisfactory procedure. TinyDB is a based on Tiny0S data query processing middleware, provides an energy-saving data query function. The data aggregation TinyDB fusion provides very good support, but there is no other middleware services to provide. And the above method is compared to several system, the method on the wireless sensor network including improving the function of data processing, storage, excavation, a plurality of software upgrading mode, flexible power management module, and the support of the multi-programming language, the sensor network and support heterogeneous.
