AGway - An IoT Gateway

It is predicted that by 2020, 50 billion devices are going to flood the IoT space. IoT devices also form networks among themselves so that they become manageable self groups. Majority of these devices are going to be edge nodes with minimal processingand power resources at their disposal, thereby restricting them to just sensing the environment parameters that they are designed for. Edge nodes are therefore heavily handicapped to protect themselves against any sort of attacks. It is important to mask them so that they remain invisible to the outside world.

A-Gway(Amrita Gateway) is an advance paltform, which bridges low end IOT devices to AIoTM. It can handle heterogeneous protocols such as TCP/IP,Zigbee,Bluetooth.IEEE 802.11a/b/g/n/(WiFi),6LoWPAN,UPnp. A-Gway is ideal for building real time applications.It also ensures Secure Communication Between AIoTm & Connected Devices. A Gateway for IoT (Internet of Things) often referred to as a Universal Gateway, can communicate with any type of device inside a sub network and fetch data from those diverse set of devices and push it to upper layers for further processing and analysis.Gateway has various perform, which are:

• Transform the data from within the network, so that it can be understood by applications/devices existing outside the network
• Avoid malicious data from entering and leaving the network.
• Proper authorization of the data and verifying the source of the data from both within and outside the network

Some Of Its Features

• Bridges IoT devices to IoT network middleware.
• Hosts and IoT service enabled devices allow real-world interaction.
• Gateway supports all the services and protocols demanded by AIoTm middleware.
• Best suits streaming real-time applications.

AGway Services

• Streaming: Involves acquiring sensor data from end-user sensor devices and transfers the same to middleware.
• Request Response (RR): RR Service is mainly used in ZigBee Device Search, Bluetooth Discovery, UPnP Service Invocation.
• Device Health Check: Periodic health check allows tracking of device.
• Modes: Power Saving or Transmit on State Change mode.
