Game Theory Based Power Allocation Algorithm in High-Speed Mobile Environment
Recently, the high-speed railway has developed rapidly. In a wireless fading channel, sharing the same physical resources, User Equipments (UEs) with High speed (HUE) and UEs in a Macro cell (MUE) interfere with each other. A power allocation scheme in high-speed mobile environment is considered to suppress such interference. Specifically, the authors' power allocation scheme aims at maximizing the effective capacity of users. Besides, each user tries to compete for these resources to satisfy its own Quality of Service (QoS) guarantee. In order to handle the selfish behaviors of two users, the power allocation problem for the MUE and the HUE is modeled as a non-cooperative game.
