This is largely due to their ease of use provided by robust interoperability and feasibility in almost any scenario. Internet of Things (IoT) can be a great tool to achieve this goal of connecting people and devices everywhere all the time. IoT is a network of various types of devices connected together to seamlessly data transfer without any computer or human interaction. IoT can be defined as a network consisting of many small sensor nodes whose main purpose is to collect data from surrounding environment and then forward to the base station. Firstly, we develop a theoretical model of physical layer of Wireless Sensor Network (WSN). Next, we derive the energy efficiency expression and solve the optimization problem of energy efficiency under the constraint of Packet Reception Rate (PRR). Two application perspective of IoT such as biomedical and smart home appliance has been proposed. Modeling of WSN using MATLAB to perform simulation of real human body have been analyzed. A model of smart juice maker has also proposed here which can be controlled from mobile apps.62 pagesenBRAC University theses are protected by copyright.
