The key emergent technology named Internet of Things (IoT) is used in various industries and daily activities of individuals. The IoT sensors are a battery operated one that is connected with internet over various services than ranges between healthcare and industries. Energy conservation or energy efficiency of these sensors is an utmost concern since most of the IoT devices powered with battery may often die while transmitting the data between the other devices. Various researches are conducted to conserve the energy via energy conserving mechanism. In this paper, we develop a multi-objective optimization model to resolve the higher energy consumption by the IoT devices under different diverse environment. These IoT devices communicates wirelessly with other devices in terms of WiFi connectivity and hence the study analyses the efficacy of the model. The experimental results show that the multi-objective modelling of energy conservation shows a reduced consumption of battery power by the IoT devices than conventional mechanisms.
