IDT SensorShare Technology, Wireless Sensor Network

IDT SensorShare wireless communication firmware libraries lower the burden of connecting sensor node devices to one another securely and reliably with configurations for cloud-enabled connections. SensorShare is a 6LoWPAN open standard stack that communicates natively with IPv6 (internet protocol) over IEEE 802.15.4 radio links. SensorShare handles the local data exchange between sensor nodes and end devices within the network, and when implemented as the edge router, Sensorshare manages the data exchange to different networks or the Internet. SensorShare data packets are securely routed from point to point or multiple hops in a mesh network.

Addresses Challenges in Deployment of IoT Wireless Sensor Networks

With the emergence of Industry 4.0, the fourth revolution in manufacturing, more end device data is being pushed to the cloud. As a result, interoperability between network systems remains a complex challenge. 

Network protocols such as LoRa, Zigbee and Z-wave must be managed properly in case application layer changes are not updated seamlessly through the entire end device to the network. When connecting these devices to the Internet, a high degree of skill and knowledge is required to develop the system from the ground up, as well as make necessary changes to the application layer. 

System architects are confronted with many of these constraints and requirements when selecting the most fitting technology for a specific IoT application. However, the most challenging task is integrating different hardware with software, as these network technologies may be proprietary and incompatible. For example, sensor nodes and end devices in an IoT network may be moved to another location, added, or removed. These and many other barriers make it difficult for new designers, developers and companies to tackle IoT implementation. 

The SensorShare platform helps overcome these challenges by offering a complete software in hardware solution designed to be an open standard that connects via device-to-device, device within a local network, and device to cloud. SensorShare is offered with no license fee and has no royalty fee.

Turnkey Sub-GHz Transceiver Module Solutions Simplify Deployment

While there are a vast amount of IoT hardware building blocks available in the market, many solutions labeled as “turnkey” are proprietary networks. These require data subscription fees that quickly become cost-prohibitive. The ramp up to develop the system and application firmware with these solutions are steep and require dedicated resources and open-ended time allocation. 

IDT simplifies the technology selection and design phase by offering 6LoWPAN, ultra-low-power wireless transceiver modules and development kits embedded with the SensorShare firmware. It provides a truly plug-and-play turnkey solution that accelerates wireless sensor network deployment and allows allocation of resources to top-level application layer development. In addition, with the pre-provisioning and configuration to cloud-based services such as Amazon Web Services (AWS), developers can access real-time sensor data and readily utilize services such as data analytics and machine learning. In addition, IDT’s sub-GHz transceiver modules are certified for use in various global regions.

Advantages of 6LoWPAN for Wireless Sensor Networks

From a small local sensor network used for monitoring several points of use to a network spanning meters in range with ad-hoc sensor nodes or hosts, 6LoWPAN excels in low overhead ultra-low power (using UDP) data routing to worldwide use in the Sub-1 GHz frequency bands.

6LoWPAN enables transmission of IPv6 over IEEE 802.15.14 radio links by adding an adaptation layer between the data link layer and network layer of the open systems interconnect (OSI) model. With IPv6, 3.4*1038 unique addresses are available to cover the tens of billions of connected devices to come. 

As an open standard, 6LoWPAN is closer to full interoperability with other manufacturer devices and builds on top of existing IP communication networks. IDT modules utilize Sub-1 GHz frequency bands for better signal propagation (rather than the crowded 2.4 GHz band) and support large mesh network topology for long range with very low power consumption. 

With IDT SensorShare, long distances are covered with mesh routing. Each sensor node or end device uses other nodes as relays, and nodes can be added and removed at any time. This self-healing ad-hoc mesh network solves the scaling or reduction problems of the system at any time.
