Wireless Sensor Network in IoT and Performance Optimization

A serious problem in Wireless Sensor Networks (WSNs) is to attain high energy efficiency as a battery is used for power generation that has limited stored energy. They can not be suitably replaced or recharged. The appearance of renewable energy harvesting techniques and their combination with sensor devices gives Energy Harvesting Wireless Sensor Networks (EHWSNs). IoT is now becoming part of our lives, comforting simplifying our routines and work life. IoT is very popular. It connects, computes, communicates, and performs the required task. IoT is actually a network of physical devices or things that can interact with each other to share information. This paper gives an overview of WSN and IoT, related work, different ways of connecting WSN with the internet, development of smart home, challenges for WSN, etc. Next, a framework for performance optimization in IoT is given and QC-PC-MCSC heuristic is analyzed in terms of energy efficiency and life time of a sensor on energy latency density design space, a topology management application that is power efficient. QC-PC-MCSC and QC-MCSC are compared for energy efficiency and life time of a sensor over energy latency density design space, a topology management application.
