How IoT Protocols Secure Data Exchange in the IoT
Sphere

• With the continuously increasing number of IoT
  devices, cases of DDoS attacks are also being
  witnessed frequently. According to
  a Statista report, the number of connected
  devices will reach about 31B by 2020. Thus, this
  is the time when businesses, customers,
  stakeholders, and IoT app developers should
  garner knowledge about IoT protocols that can
  significantly hold the chances of security
  breaches at bay.

A Comprehensive Guide to IoT Protocols

• IoT protocols are modes of communication that
  ensure end-to-end security of the data exchange
  between connected devices.
• Basically, the IoT devices are connected to the
  cloud through an IP network. However, Bluetooth
  and RFID devices allow IoT systems to connect
  locally. In both cases, there is a difference in
  range, power, and memory consumption. IP network
  connectivity is relatively complicated, requires
  more power and memory from the IoT devices while
  the range is not an issue. On the contrast,
  non-IP networks need less memory and power and
  are limited to a specific range. As far as the
  IoT protocols are concerned, a blend of IP and
  non-IP networks can be considered as per to their
  usage.
• Lets have a look at them.

HTTP (HyperText Transfer Protocol)

• HyperText Transfer Protocol has built the
  foundation of data transmission over the web.
  This protocol is commonly used for IoT devices
  when there is a massive amount of data to be
  published. However, HTTP is not the first choice
  of most IoT app developers because of its battery
  life, cost, energy consumed, and many other
  constraints.
• 3D Printing is one of the best use cases of the
  HyperText Transfer Protocol. It connects
  computers to the 3D printers over the network and
  enables systems to print 3D objects and
  pre-determined process prototypes.

LoRaWan (Long Range Wide Area Network)

• Loran is a low-power, long-range protocol that
  offers signals detection below the noise level.
  It connects battery-powered devices to the
  internet, wirelessly in private or global
  networks. This protocol is mainly used by smart
  cities, where there a myriad of devices that
  operate with less power and memory.
• Smart street lighting is the most significant use
  case of the LoRaWan protocol. This protocol
  facilitates the connection of street lights to
  the LoRa gateway. The LoRa gateway further
  connects to the cloud app that controls the
  intensity of light bulbs and reduces power
  consumption during the daytime.

5
Bluetooth

• Bluetooth is an extensively used protocol for
  wireless, short-range, low-cost, low-power, and
  secure data exchange between electronic devices.
  Bluetooth Low Energy (BLE) is a subset of this
  protocol that cuts down power consumption and
  plays a significant role in connecting IoT
  devices.
• Bluetooth protocol is mostly used in smartphones,
  smart wearables, and other devices, where small
  chunks of data can be communicated with low
  energy and memory consumption. With such high
  usage and demand, Bluetooth is deemed the most
  preferred IoT connectivity protocols by every IoT
  development company.

 Message Queue Telemetry Transport (MQTT)

• MQTT protocol gathers data from multiple
  electronic devices and supports remote device
  monitoring. It is a publish/subscribe protocol
  that operates over TCP (Transmission Control
  Protocol), enabling it to support event-driven
  data communication via wireless networks.
• MTQQ is mainly used in economical devices and
  demands less power as well as memory. For
  example, smartwatches, fire detectors, car
  sensors, and apps for text-based messaging.

7
Constrained Application Protocol (CoAP)

• CoAp is an internet-utility protocol for
  restricted devices. This allows the client to
  send a request to the server, and then the server
  can respond to the clients in HTTP. CoAP uses
  User Datagram Protocol (UDP) and reduces memory
  consumption for light-weight implementation.
• Constrained Application Protocol is chiefly used
  in mobiles, automation, and microcontrollers. It
  sends a request to the app endpoints like
  appliances at homes and reverts resources and
  services in the application.

8
Advanced Message Queuing Protocol (AMQP)

• This is a software layer protocol for
  message-oriented middleware infrastructure that
  renders queuing and routing. AMQP provides
  reliable point-to-point connections and ensures
  secure data exchange between the connected
  devices and the cloud. This protocol comprises
  three components, named Message Queue, Exchange,
  and Binding, responsible for seamless, secure,
  and successful message exchange and storage. It
  also facilitates the relationship establishment
  of one message with another.
• AMQP is mostly used in the banking sector. When a
  server sends a message, the protocol tracks it
  until is it is delivered to the destinations
  without hindrance.

9
Machine-to-Machine (M2M) Protocol

• M2M is an open industry protocol accountable for
  remote application management of IoT devices.
  This protocol uses public networks and creates an
  environment where a machine can easily exchange
  data. Besides, it supports the self-monitoring of
  equipment and facilitates system adaptability to
  match with the changing environment.
• M2M protocol is used for automated vehicle
  authentication, smart homes, ATM machines, and
  vending machines.

Final Words

• According to the Economic Times, over 32,000
  smart homes and businesses are at risk of data
  leakage. Knowing and exploring the potential of
  the afore-mentioned IoT protocols will help you
  to create a secure environment for communicating
  data with the cloud.
• Since choosing an appropriate type of
  connectivity and protocol is an inevitable aspect
  for a successful IoT project, we suggest to
  consult the experts of a smart IoT Development
  Company. They will navigate you in your IoT
  project journey right from ideation and
  conceptualization to development and deployment.
