Building an IoT Network

Building a IoT network can be overwhelming, but with a key objective/goal in mind and the right tools and support, you can make your idea come to life.

The IoT Hardware Toolkit

In your network toolkit, you will typically have Sensors and Actuators (to collect data and activate things), Controllers (to combine and process the data from the sensors and control the actuators) and Gateways (to provide coverage to your sensors and connect to the internet so data can be passed data back and forth to the application). You will also need to be able to view and manage your data, that is where Scopious excels.

    5 Key IoT Aspects You Must Consider When Designing an IoT Network

    • The scale of a typical IT network is on the order of several hundred devices—typically printers, mobile wireless devices, laptops, servers, and so on.

      But when a scale of a network goes from a few hundred endpoints to hundreds of thousands, the IT engineers lack the required skills to design a network that is intended to support millions of routable IP endpoints.
    • The frequency and impact of cyber attacks in recent years has increased dramatically. Protecting corporate data from intrusion and theft is one of the main functions of the IT department.

      IoT systems require consistent mechanisms of authentication, encryption, and intrusion prevention techniques that understand the behaviour of industrial protocols and can respond to attacks on critical infrastructure.

      For optimum security, IoT systems must:
      • Be able to identify and authenticate all entities involved in the IoT service (i.e., gateways, endpoint devices, home networks, roaming networks, service platforms).
      • Ensure that all user data shared between the endpoint device and back-end applications is encrypted.
    • Most IoT sensors are designed for a single job, and they are typically small and inexpensive. This means they often have limited power, CPU, and memory, and they transmit only when there is something important.

      If an IT network has performance constraints, the solution is simple: Upgrade to a faster network.

      With IoT, if too many devices are on one location and it is impacting performance, we can simply add more capacity to scale as much as we need.
    • IoT devices generate a mountain of data. In general, most IT shops don’t really care much about the unstructured chatty data generated by devices on the network.
      However, in IoT the data is like gold, as it is what enables businesses to deliver new IoT services that enhance the customer experience, reduce cost, and deliver new revenue opportunities.

      Although most IoT-generated data is unstructured, the insights it provides through analytics can revolutionize processes and create new business models.

      For example :
      • Imagine a smart city with a few hundred thousand smart streetlights, all connected through an IoT network.

      Without the proper tools however, when all this data is combined, it can become difficult to manage and analyze effectively, and difficult to identify needed solutions.
    • Supporting legacy devices in an IT organization is not usually a big problem. If someone’s computer or operating system is outdated, they simply upgrade. If someone is using a mobile device with an outdated Wi-Fi standard, such as 802.11b or 802.11g, we can simply deny them access to the wireless network, and they will be forced to upgrade.

      In IoT systems, end devices are likely to be on the network for a very long time—sometimes decades.

      As IoT networks are deployed, they need to support the older devices already present on the network, as well as devices with new capabilities.

    There is a direct relationship between the IoT technology we choose, and the type of connectivity topology this technology allows

    Your Hardware Checklist

    What to connect, where to connect, how much data to transport at what interval and over what distance.

    What do you need?

    • Battery-powered or power-connected?

      This classification is based on whether the object carries its own energy supply or receives continuous power from an external power source.

      Batteries limit the lifetime and amount of energy that the object is allowed to consume, thus driving transmission range and frequency
    • Mobile or Static?

      This classification is based on whether the “thing” should move or always stay at the same location.

      A sensor may be mobile because it is moved from one location to another or because it is attached to a moving object.

      The frequency of the movement may also vary, from occasional to permanent.
    • Low or high reporting interval?

      This classification is based on how often the object should report monitored parameters.

      • A rust sensor may report values once a month.
      • A motion sensor may report acceleration several hundred times per second.

      Higher reporting intervals drive higher energy consumption
    • Simple or rich data?

      This classification is based on the quantity of data exchanged at each report cycle.

      • A humidity sensor in a field may report a simple daily index 
      • While an engine sensor may report hundreds of parameters, from temperature to pressure, gas velocity  etc.
      • Richer data typically drives higher power consumption.
    • Report Range

      This classification is based on a combination of; sensor capabilities, the number of smart objects over a given area, transmit power, antenna gain, obstructions and the height and distance between the smart objects and where the gateway is located.
    • Sensor density per cell

      This classification is based on the number of smart objects over a given area connected to the same point of access.
    Checklist

    Your Connectivity Options

    Data collected from a smart object may need to be forwarded to a server where data is processed. One key parameter determining the choice of access technology is the range between the smart object and the Gateway.
