Towards Secure IoT Networks in Healthcare Applications: A Game Theoretic Anti-Jamming Framework

Document Type


Publication Title

IEEE Internet of Things Journal


The internet of Things (IoT) is used to interconnect a massive number of heterogeneous resource constrained smart devices. This makes such networks exposed to various types of malicious attacks. In particular, jamming attacks are among the most common harmful attacks to IoT networks. Therefore, an anti jamming power allocation strategy is first proposed in this paper for health monitoring IoT networks by exploiting game theory to minimize the worst case jamming effect under multi channel fading. This strategy uses an iterative algorithm based on gradient descent to identify the Nash Equilibrium (NE) of the game. An artificial neural network model is also proposed to accelerate the convergence of the algorithm making it more suitable for IoT networks. Furthermore, novel data population, extension and balancing techniques are proposed to enhance the efficiency of the proposed strategy in combating jamming attacks even for network configurations that were never used in the training phase. In addition, time and spatial diversity are exploited using a heterogeneous iterative algorithm to enhance the security of the network. IEEE
