摘　　要：讨论了无线传感器网络在复杂环境下的服务构建及并发控制。基于传感器网络能量、通信能力、计算存储能力等有限的特点提出了面向传感器网络的服务管理,提出了基于推理的上下文感知工作流来构建传感器网络服务。通过提取传感器数据的语义信息,实现了上层业务逻辑和底层传感器数据的松耦合,实现了传感器网络的资源重用。此外,改进了Web服务请求的并发控制,通过服务请求的重复和冲突检测,避免重复和冲突的服务执行,实现更有效的传感器网络并发控制。This paper researches the service building and concurrency control in wireless sensor networks（WSNs）.Due to the characteristic of limited resources such as energy,communication,computing and storage in WSNs,a WSN service management approach and a reasoning-based context-aware workflow to build WSN services are proposed.By abstracting the semantic information from sensor data,the loose couple between the upper business logic and lower sensor data can be achieved and the resource reuse can further realized.In addition,the traditional concurrency control methods are improved.With the help of repeat and collision detection,more effective WSN service concurrency control can be received.
