摘　　要：通过分析无线传感器网络(WSNs)的特性及其应用特点,提出了一种新型的基于合作域的无线传感器网络数据存储机制,以便在节约节点能量和内存开销的前提下提高数据的可靠性。指出了其设计目标和体系结构,定义了数据存储合作域、管理节点及其建立机制,给出了在合作域内根据网络编码理论进行数据存储与提取的算法与流程。通过仿真测试,证明其能够在较低的资源开销下提高信息的可靠性。By analyzing characteristic and application of wireless sensor networks （WSNs）, propose a new kinds of data storage meachanism for WSNs based on cooperation region, in order to improve data reliability under the premise of node energy-saving and memory overhead. Point out design object and system architecture, define mechanism for providing in-network storage service in sensor environments, and define data storing cooperation region, manager node and its establishment mechanism algorithm and flow for data storage and extraction are given based on network coding theory in cooperation region. Simulation results show that the mechanism is capable to improve information, reliability with low energy overhead.
