英文摘要： The problems of energy constraint and low data transmission efficiency are the key issues which limit the large scale deployment and the future development of wireless sensor networks. The development of MIMO techniques enables long distance, low energy consumption, high efficiency data transmission to be realistic. This proposed project focuses on the key theory of applying MIMO techniques to practical wireless sensor networks, which contains three main perspectives: the fundamental theory of the channel capacity/energy consumption features of cooperative virtual MIMO; the implementation mechanisms, the protocol and algorithm design of virtual MIMO sensor networks based on the deployment scenarios, topologies, and sensed data characteristics; and the optimization of MIMO sensor network systems. It will also solve the problems of the MIMO implementation mechanism selection and system parameter choice. Based on the theoretical study, large scale wireless sensor network testbed will be built and the system level experiments will be carried out. The proposed theoretical output of this project will be used as the fundamental theory of applying MIMO techniques to wireless sensor networks. This project will also make great contributions to the area of long lifetime stable large scale sensor networks.
