The Tenet project is developing an alternative architecture for tiered wireless sensor networks that contain both small-form-factor motes and high-powered nodes called masters. The Tenet project's guiding architectural principle asserts that multi-node data fusion functionality and complex application logic should be implemented only on the masters, since the cost and complexity of implementing this in motes outweighs the performance benefits of doing so.Tenet thus simplifies and standardizes the design and construction of the most difficult-to-handle software on a sensor network. It restricts mote communication to trees rooted at masters. Tree communication is well understood, leads to more predictable communication patterns and improves the manageability of the mote tier. Direct inter-mote communication would destroy much of this predictability and manageability.The project is designing and prototyping the Tenet stack. This stack embodies the Tenet architectural principle and can be reused by several applications. The development of such a stack for large-scale sensor networks will greatly accelerate the development of a variety of applications ranging from habitat monitoring to structural monitoring. Without a Tenet-like architecture, sensor network deployments will never truly impact the world.

Tenet项目正在为分层无线传感器网络开发一种替代架构，该架构既包含小尺寸微尘，也包含称为Master的高性能节点。Tenet项目的指导架构原则认为，多节点数据融合功能和复杂的应用逻辑应该只在主机上实施，因为在微尘中实施这些功能的成本和复杂性超过了这样做的性能好处。Tenet因此简化和标准化了传感器网络上最难处理的软件的设计和构建。它将微尘交流限制在植根于主人的树木上。树通信很容易理解，导致更可预测的通信模式，并提高了微粒层的可管理性。直接的远程通信将在很大程度上破坏这种可预测性和可管理性。该项目正在设计和制作Tenet堆栈的原型。该堆栈体现了Tenet体系结构原则，可供多个应用程序重用。这种大规模传感器网络堆栈的开发将极大地加速从栖息地监测到结构监测的各种应用的发展。如果没有类似Tenet的架构，传感器网络部署将永远不会真正影响世界。
