A Hierarchical Framework of Dynamic Relay Selection for Mobile Users and Profit Maximization for Service Providers in Wireless Relay Networks
Although, extensive research has been carried out on the issue of how to optimally select relays in wireless relay networks, relay selection for mobile users is still a challenging problem due to the requirement that the dynamic selection should adapt to user mobility. Moreover, since the selected relays consume their energy on relaying data for the users, it is required that the users have to pay for this relay service. The price of selecting relays will affect the users' decisions. Assuming that different relays can belong to different service providers, the authors consider the situation that the service providers can strategically set the prices of their relays to maximize their profits.
