Game theory is not only useful in understanding the performance of human and autonomous game players, but it is also widely employed in solving resource allocation problems in distributed decision-making systems. Reinforcement learning is a promising technique that can be used by agents to learn and adapt their strategies in such systems. We have enhanced the carrier sense multiple access with collision avoidance mechanism used in random access networks by using concepts from the two fields so that nodes using different strategies can adapt to the current state of the wireless environment. Simulation results show that the enhanced mechanism outperforms the existing mechanism in terms of throughput, dropped packets and fairness. This is especially noticeable as the network size increases. However the existing mechanism performs better in terms of delay which can be attributed to increased processing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
