In the vast wilderness of technology, control systems have taken a preeminent position. From
simple kitchen wares to rocket sciences and space shuttles, everything is surrounded with
automated marvels of technology. There are home automation systems (HAS), heating,
ventilation and air-conditioning system (HVAC), responsive surveillance systems etc. which lie
under the domain of control systems. Porting anything on the internet means that its being
made available on the global network of computers. Twenty first century has seen a tremendous
breakthrough in the field of networking. Internet has made almost everything connected and
made the utopian concept of global village, an amazing reality. This project basically deals with
the concept of internetworking of physical resource collectors and control units or otherwise
known as Internet of Things (IoT).
We have made a mesh network of sensors and connected it to an embedded TCP/IP server to
demonstrate the idea. We connected some control appliances and sensors to the server and
forwarded the port of the server on the internet. User interface was provided in an android app
to connect to the server in both LAN and WAN mode. Security procedures have also been
deployed to eradicate any possibility of breach.
