The user can apply algorithms for analysis, machine learning at NebuLink middleware, it also provides an interface for application developers to implement end user applications.

COMMUNICATION

Nebulae has a wide range of wired and wireless communication mediums, making it suitable for many IoT solutions. Nebulae networking uses communication standards defined by IEEE and IETF. Nebulae communication mediums include IEEE 802.15.4 (LR-WPAN), IEEE 802.11 (WiFi), IEEE 802.15.1 (Bluetooth), IEEE 802.3 (Ethernet), GSM 2G, GSM 3G and LTE.

WIFI

The Nebulae SDK has a proprietary IoT Messaging System for building rules engines in sensing devices. It also allows the definition of multifunctional network devices, which simplifies development.

Bluetooth

Bluetooth is a short range technology. It is reliable only when endpoints are used within the same room of an access point. So we are pairing Bluetooth with other wireless technology in the following way : Dozens of end points in an area are


connected back to one master device, which acts as the Bluetooth access point. Then, that device uses another form of connectivity to communicate with the back end.

802.15.4

802.15.4 (LR-WPAN) is a full handshake protocol for transfer reliability, power management to ensure low power consumption, automatic network established by the coordinator. 802.15.4 is used to establish a Wireless Sensor Network (WSN) to connect your sensors and actuators to the internet.

INTEROPERABLE

Developers and manufacturers of the IoT industry are facing challenges to make their devices and products interoperable. Reason for making any IoT enabled device to be interoperable is, it should provide the abilities to the system to integrate, function and communicate with other products of third party devices.

The Nebulae IoT solution provides this feature of Interopeability to its developers as well as users. Our Eclipse IoT based NebuLink Gateway framework and ZigBee based NebuLink Nodes enable Interoperability to Industrial standards and devices based on those standards.

WIRELESS SENSOR NETWORK

Nebulae supports wide range of network topologies like Tree, Mesh, Hybrid, etc.

Nebulae also supports three type of communication:

Multipoint to Point (MP2P)

Point to Multipoint (P2MP)

Point to Point (P2P)

NebuLink Device in WSN has unique feature of Self Healing and Self Configuring. Empowering NebuLink Nodes to evaluate and select the best route to NebuLink Gateway automatically. For any Wireless Network it's important to deliver messages without any loss. Nebulae WSN guarantees 100% availability and access to Network devices having the support of Total Mobility, High Scalability and Extreme Ruggedness with high QoS.

Time Synchronization

  • Network synchronization maintains precise synchronized times in every NebuLink Node of a Nebulae Network.

  • Make Most of Your Data

  • Nebulae Network offers precise time stamping of events, sensor data so you can make the most out of raw data.

  • Schedule an event

  • Precisely synchronized networks can be used for scheduling of events as well.

Self Healing Network

  • Nebulae self healing network detects and reroutes broken path immediately. When a new device is powered on, it will directly join the network by connecting to nearby device or with gateway, without any human interaction.

  • Also Nebulae supports mobility, means if you move your device then it will dynamically change its path in no time. So you will get your device accessible all the time from anywhere. Nebulae uses advanced routing algorithm that reduces overhead of WSN, that also helps to reduce power consumption.

  • This self Healing feature gives Nebulae network's ability to withstand harsh environmental conditions.

SECURITY

Security in IoT is a vital part of establishing the connected network. The Nebulae Solution comes with strong security solutions to meet the most challenging use cases.

Key features of security :

AUTHENTICATION

Authentication process identifies users, computers, devices and machines in networks and restricting access to authorized persons. Cryptographic mechanism is a more robust way of securing communication over the Internet of Things.

Hardware based security supports authentication by providing secure storage for a device’s credential (Encryption/Decryption keys or passwords).

SECURED COMMUNICATION

All packets over WSN are encrypted by Link layer security which is unique for a network. Gateway selects its LLK(Link layer key) during the registration process. DTLS, TLS over UDP, provides application layer security.

SECURE FIRMWARE UPDATE

Firmware update in the field requires robust and hassle free secure firmware validation and installation. Nebulae framework involves separate key for encryption for transferring firmware to nodes.

CRYPTOGRAPHIC KEY GENERATION MANAGEMENT

Nebulae framework generates Encryption keys for different layers using a unique key generation algorithm. These keys are never exposed to User.

CONFIDENTIAL DATA STORAGE

Nebulae devices store information related to network, security, credentials parameters, etc. using 128-bit AES.

FIRMWARE UPDATE

Why does firmware need to be updated?

Remote firmware and software updates are an essential feature of any smart devices. Updates enable devices to run the most recent and more secure software.

Different devices have different methods of downloading and installing new firmware like Nebulae has its unique method to update Nebulae devices.

Firmware update in Nebulae

Device Firmware updates are initiated at the IoT cloud service. The IoT cloud service delivers the update commands based on defined business process and policies.

Device keeps IoT cloud informed abour current state of update process. And assures that current work is not affected due to update process. User is allowed to stop, pause or resume update process at any time.

SECURITY

Firmware transfer over network and air is secured by Standard Encryption Algorithms. Nebulae Devices uses several validations to identify any temper or corruption of firmware.

TRAFFIC MANAGEMENT

Firmware download speed can be controlled based on traffic in the network. So network will not be affected due to Firmware update process regardless of size of the network.

NOTIFICATIONS

The device will send notification of each stage of the firmware update process. Like Installation started, 10% downloaded, 100% downloaded, Firmware installed, Firmware not supported, Firmware timeout, Firmware not available.

User can perform regular activities while the firmware update process is in execution.

DUAL RF FRAMEWORK

Nebulae Framework is enhanced with new features “Dual Radio Channel”.

  • The 2.4 GHz radio is intended for in-door use, such as a Home Area Network (HAN), whereas the sub-GHz radio is good for out-door networks ,such as a Neighborhood Area Network(NAN), and in-door networks that need a longer range.

  • Nebulae framework for Nebulink Gateway works as solitary rather than multiple stack.

  • NebuLink Gateway is a bridge between HAN(2.4GHz) and NAN(Sub-GHz) RF network, which can forward data both of the RF network.

IIOT GATEWAY WITH SOC AND FPGA

  • Industry 4.0 and the Internet of Things (IoT) are trending with ever-growing data streams, and these streams contain important and valuable business information for those organizations that are capable of processing them in real time.

  • Organizations require output immediately, not next week or next month. Current market solutions haven’t allowed for fast, accurate data analysis, using all of the data available on site.

  • The result has been that decision makers have been forced to act on outdated, inaccurate, and/or incomplete data, which means that the decisions are compromised.

  • NebuLink Gateway with FPGA accelerates IoT systems and benefits data scientists, business analysts and solution providers with real time data analytics for better, accurate and faster decision making.

  • This capabilities allows advanced machine learning capabilities to be proliferated into tiny sensors and devices covering wide application area such as Aerospace, Defence, Financial sector, Smart Homes, connected cars, wearable, Smart Manufacturing, Smart Grid, Smart Agriculture, Water and Waste management, Smart Transportation and many more.
