A simulation model for estimating the service life of the Internet of Things under the conditions of attacking effects emitting the node energy

The low power of the sensor nodes of the Internet of Things determines the search for solving several urgent problems: increasing the service life of sensor nodes and the security of the Internet of Things. Sensor nodes use batteries with limited resources as a power source, therefore if a sensor network is installed and deployed in a remote geographic space to observe physical phenomena, then recharging or replacing sensor nodes may become impossible or expensive due to the long distance. Power consumption is one of the important quality indicators of the Internet of Things defined as the amount of energy used and spent by sensor nodes. Energy consumption determines the network lifespan – the time when the sensor network is fully functional. On the other hand, the implementation of IoT security mechanisms requires additional energy costs associated with their implementation. However, the lack of security mechanisms causes the proliferation of attacks that emit the node energy, as well as reduced service life of the Internet of Things. The paper presents the results of a simulation experiment proving that timely detection of attacks contributes to an increase in the service life of the network compared to a network with no se-curity mechanisms. To understand the operation principles of the simulation model, there is a a de-scription of its main modules, which simulate real objects of the Internet of Things network: sensor nodes, routers, protocols, communication channels, attacks, data packets. The estimates of energy consumption and service life are given in the form of graphs of dependences on various parameters of the Internet of Things network.
