Game of Resource Exploitation in Molecular Communications with Unintended Nanomachine

In many natural molecular communication systems, the transmitters exhibit the ability to collect and store the food or energy from the environment. The collected food or energy is used to produce information-carrying (IC) molecules. In scenarios, when more than one transmit node exist in the environment, they interact with each other to share the available common food molecular budget (CFMB). These strategic interactions among the nano-machines are critical to overall performance of the system. This work uses game theory to explore the effect of behavioral interactions among transmitter nanomachines (TNs) in a three-dimensional (3-D) diffusive environment where K TNs are deployed around the region of interest (RoI). The TNs share their observations to a supervisor nano-machine (SN) in presence of an eavesdropper called unintended receiver nano-machine (URN). For AND and OR fusion techniques at SN, the system performance is analyzed in terms of secured success rate (Ps), receiver operating characteristics (ROC), and average error rate (Pe). Several insights into the effects of cooperative and greedy behaviors of TNs are obtained. The results are verified through the Monte-Carlo and particle-based simulations (PBS).
