摘要
环境水质实时监测是实现水污染监控和管理的基础。为了实现大范围的水质检测,基于CC1101通信模块,文章提出了一种环境水质分布式检测的无线传感网络协议,以有效减少通信开销。文中采用分层结构进行无线传感网络协议设计,定义了消息格式,采用LBT策略和ARQ协议实现了数据的可靠传输,基于路由发现功能实现自组网。该系统在实际应用中运行稳定,取得了较好的监测效果。
Online mornitoring of water quality is the basis of the management and control of environment water pollution.For mornitoring large-scale water with low communication overhead,a wireless sensor network protocol based on CC1101 communication module is proposed by us.The hierarchical structure is used to develop the wireless sensor network protocol.The message formats are defined.LBT strategy and ARQ protocol are adopted to achieve reliable data transmission.The self-organization of wireless sensor network is implemented by route discovery.In practical application,our system runs steadily and good mornitoring results is obtained.
