In this article, we provide a novel improved model-free temporal-difference control algorithm, namely, Expected Sarsa(λ), using the average value as an update target and introducing eligibility traces in wireless communication networks. In particular, we construct the update target using the average action value of all possible successive actions, and apply eligibility traces to record the historical access of every state action pair, which greatly improve the model's convergence property and learning efficiency. Numerical results demonstrate that the proposed algorithm has the advantage of high learning efficiency and a higher learning-rate tolerance range than Q Learning, Sarsa, Expected Sarsa, and Sarsa(λ) in the tabular case of a finite Markov decision process, thereby providing an efficient solution for the study and design wireless communication networks. This provides an efficient and effective solution to design further artificial intelligent communication networks.
