Mesh Sensor Networks Bridge IoT’s Last Mile


Delivering Greater Resiliency with a Hybrid Topology and IoT Gateways By Paul Richards, CEO, and Bill Goretkin, VP Engineering, Wireless Sensors


tion of wireless sensors and the gateways needed to connect them to the Internet of Things (IoT). By allowing low-cost sensor deployment, these gateways enable visibil- ity into previously opaque operational details. The benefits become even more profound with the application of advanced analytics.


T


he adage, “You can’t control what you don’t measure,” has great relevance for energy and industrial-process optimiza- tion. The need for data in these industries is driving rapid adop-


There is a major challenge though in achieving these benefi ts. Companies need to determine the best way to connect legacy systems isolated by non-IP-friendly communication protocols such as Modbus RTU.


This article explores a solution from Wireless Sensors that connects sensors in self-confi guring and self-healing wireless mesh networks that communicate to the cloud through Intel®


NUC-based IoT gateways


(Figure 1, on page 56). We describe how this solution combines the fl exibility and resilience of mesh networking with the low latency of a star topology. We discuss how the IoT gateways support RESTful web services and integration with the Microsoft Azure* platform to provide a seamless data path to the cloud and advanced analytics. And we con- sider the advantages of using an Intel®
