The Remote Enabled Multi Sockets(REMS)

Abstract

 In recent years, a lot of research work has been proposed on routing scheme in WSN. Remote Accessing is one of the most promising techniques due to its simplicity, scalability and efficiency. Under many research and development cell, it has been noted that establishing the wireless sensor nodes and let them work as a cluster, but the major problem with the wireless technology has limitation of range. The solution of this issue is to use Radio frequency as a way to communicate in a cluster. As REMS mainly focuses on the Agricultural sector, where the lands are present remotely with issues of Internet connectivity which is the main requirement for the present IOT devices. That is why we aim to develop a system which entirely runs on its own private network without any need of Internet connectivity. The system is easy to use and has a long range. The system also doesn’t require a smart phone as it is interface free, it can be controlled with a simple keypad phone. The cost effectiveness and the mentioned features makes REMS a system, which can independently survive in remote agricultural lands. Thus, the creation of this system will help farmers for controlling the devices which run on electricity (e.g. Irrigation Motors) as the system is cost effective, has long range and a internet free technology.

Recently, Automation is one of the most growing terms in India. Day by day automation can be seen in various fields. Households, Offices, Industries are the prime areas where automation is contributing a lot. When we talk about agricultural Automation, it has still not reached many parts of India which leads to inconsistency in production and many more problems. Most of the land in India is occupied by agriculture, and as India is making progress continuously in IT and Automation, its needed to bring some reliable system of automation. This Project aims to provide farmers a better, cost-effective and reliable electrical equipment automation system.

 The system actually works in a cluster and has a master and a slave node. The master controls the entire cluster, commands and acknowledges all nodes in a cluster and communicates with the user which includes task like accepting the commands from the user with the help of DTMF, broadcasting the received command by the user into the cluster with the help of WSN and also sending a status message to the user. The nodes also process the signals or commands sent by the master with the help of their logic and serves the commands intended to them and acknowledge to the master accordingly. Figure 1 provides a basic block diagram of the REMS and Figure 2 provides a detailed block diagram which can facilitate in interpreting the architecture and communication inside the cluster.
