Abstract
We developed L3SN, a scalable, longevous, adaptive, and internet accessible wireless sensor network system for agriculture information monitoring, which is meticulously designed to meet the requirement of thousands hectares coverage, years of time monitoring and the adverse environment. The system architecture, the agriculture sensor device, the mesh protocol, and the web-based information processing platform are introduced. We also presented some implementation experience. The mesh protocol (LayerMesh) is highlighted, in which “stair scheduling” and “distributed dynamic load-balancing” are proposed to response the scalability, longevity and adaptivity requirements. We believe the design of L3SN is useful to many other large-scale, longevous applications such as hydrologic monitoring, geological monitoring etc.

Summary
Agriculture Informatization is an important area, related to people life and national interest, is proposed to be empowered by wireless sensor network technology. The water, soil conditions, the crops, fruits conditions, as well as the conditions of livestock are required to be monitored in real-time by many spatially distributed wireless sensors These wireless sensors are battery or solar energy powered, equipped with wireless radio, storage unit, data processing unit and various sensing units. They are desired to be deployed into the large-scale farmland, to self-organize to a functional distributed multi-hop network via wireless communication, to work for years of time to collect data, and to be self-maintenance against the environmental dynamics of the four seasons.
