专有协议可以降低简单传感器网络的成本吗？
行业标准，如ZigBee放大器和蓝牙智能是最知名的协议目前正在设计成智能生活和家庭自动化设备，如照明和暖气控制，计量，安全和安全系统。然而，其他选项可供设计师，包括一些专有的协议，可以提供优势，如更短的学习曲线，成本较低，功耗低，适合电池供电的家电。
专有的无线协议中，德克萨斯仪器SimpliciTI™是一个简单的协议设计的小型RF网络具有低数据速率和低功耗的要求，需求。它的目的是支持对等拓扑结构，使用接入点（AP）在一对一的连接，或作为一个星形拓扑的中心。因此，SimpliciTI是被设计来分享传感器数据如占用系统的有力竞争者，光和/或温度控制的智能照明信息。它还可以支持通信设备，如射频遥控器，包括车库门开启器，以及智能仪表，安全设备，如气体传感器和烟雾探测器，安全传感器，以及各种其他设备
SimpliciTI has some important attractions for embedded designers. For one， the network protocol is provided as source code under a free license without royalties. It also imposes minimal demand for system resources， requiring less than 8KB of Flash and 1KB of RAM depending on configuration. At the same time， however， it allows versatile network topologies suitable for connecting various types of devices such as sensors， actuators and RF tags， thereby enabling designers to fulfill numerous use cases. By supporting direct device-to-device communication， as well as simple star topologies using an AP capable of storing and forwarding messages， it has capabilities similar to those of Bluetooth Smart. In addition， by also allowing range extenders， SimpliciTI provides some of the attractive features of mesh networking protocols such as ZigBee or the forthcoming standardized Bluetooth mesh. The range is allowed to be extended up to four hops using these extenders. Figure 1 shows how SimpliciTI peers， APs and range extenders are able to support a wide range of smart-building or home-automation tasks as part of a wireless sensor network.
