Non-Cooperative Game To Balance Energy And Security In Resource Constrained Iot Networks

The restricted resources in IoT networks such as limited battery have resulted in strict requirements to prolong the network life time.To improve the communication, IoT nodes attempt to optimize the available energy in the sensor network, this makes them vulnerable to the malicious attacks from adversaries because of open scenario. In addition, enhancing the security level will consume the energy and decreases network life time. In order to balance energy and security in the network game theory concept is used. We design a non cooperative game between energy and security where the utilities of both energy and security players are maximized by controlling the number of nodes transmitting and hash length. We consider complete and incomplete information game and determine Nash equilibrium. Extensive simulation have been performed to examine Nash equilibrium. We obtained Nash equilibrium for both energy and security players.
