Reducing Energy Consumption in the IoT Systems with Unlimited Number of Devices

This paper considers a model of the Internet of Things (IoT) system with a potentially unlimited number of devices. In such systems, a large number of conflicts arises that leads to retransmissions of messages. A large number of retransmissions causes transmitter operation time growth. More transmitting time in turn increases energy consumption and reduce device battery life. For considered model a method is proposed. The method allows to reduce the average number of retransmissions for the given intensity of the input stream. As a consequence, energy consumption can be reduced. This method combines numerical computation and simulation.
