Design and development of bi-directional smart IoT gateway with interoperability for heterogeneous devices

Abstract

In the world of possibilities, IoT is playing a crucial role in development and automation of things which is making life easier, comfortable and most importantly reliable. There is a drastic growth in IoT where lager number heterogeneous devices getting connected to internet, which are monitored and controlled remotely. IoT enables to connect diverse technologies, applications and protocols which lead to interoperability between the heterogeneous wireless protocols is a disadvantage. This paper implements a new Bi-Directional IoT Gateway, which enables the communication between the heterogeneous wireless protocols and wired protocol such as (Wi-Fi, ZigBee, Bluetooth, GSM and Ethernet). It enables the interconnection and interoperability between different wired and wireless protocols, by renovating the data received from distinct wireless nodes, which is acquired from the sensors or controlling data given by remote users. GSM module is used to transmit and receive the data to cloud and from the remote users where we do not have a wired internet but only GSM network.This is mainly useful in the fields of agriculture. This Bi-directional gateway gives offers significant advantages: (i) enables the connectivity between ZigBee, Wi-Fi, Bluetooth, GSM and Ethernet. (ii) Information will be transformed into required protocol format (iii) uses a light weighted protocol for transmitting the data to cloud and receiving the data from the remote location through computer or through a mobile phone. (iv) provides local storage in the gateway and puts into cloud for analyzing and future use of the received and transmitted data (v) The sensors data can be observed and controlled over a mobile phone, tablet or a personal computer.
