Network Protocols for Efficient Distributed Control in Agriculture
暂无分享,去创建一个
Data networking for distributed data collection and control in production agriculture requires a
network with versatile capability to manage communications between mobile nodes and fixed nodes. A
network protocol named AG-NETS has been developed to meet distributed control needs in production
agriculture. The AG-NETS protocol works with other networking layers to efficiently deliver data packets
across different media to extend the physical range often required for control networks in agriculture. This
protocol is an efficient means of providing this necessary versatility. Short explicit and automatic implicit
messages minimize network traffic. The AG-NETS protocol has low network overhead and can be
implemented on most microcontrollers even those with low memory resources. Implementation of the
AG-NETS protocol is presented using closed-loop control of site-specific irrigation management as an
example application.
