IoT technology The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines.  IoT is a network of sensors where data is exchanged, using different connectivity protocols, with systems. This set up can be leveraged to create a new business application or to enhance an existing process. The exchange of the data can be bi-directional between sensors and systems Examples of sensors can be temperature sensors, motion sensors, flow meters, heart meter monitors, biometric devices, smoke detectors, & etc Examples of connectivity can be wifi, radio, GPRS, GSM, LAN, WAN, & etc. Examples of systems can be a remote health monitoring applications, SCADA applications, etc Look at next slide about the complete flow of IoT process Examples A doctor in US would like to monitor the heart rate and ECG of a patient in Hyderabad.

For example, let’s name 3 computers involved in a typical forward proxy communication: A: This is a user’s home computer B: This is a forward proxy server C: This is a website’s origin server (where the website data is stored) In a standard Internet c
