Reservation Policies for Revenue Maximization From Secondary Spectrum Access in Cellular Networks

Free registration required

Executive Summary

The authors consider the problem of providing opportunistic spectrum access to secondary users in wireless cellular networks. From the standpoint of spectrum license holders, achieving benefits of secondary access entails balancing the revenue from such access and its impact on the service of primary users. While dynamic optimization is a natural framework to pursue such a balance, spatial constraints due to interference and uncertain demand characteristics render exact solutions difficult. In this paper, they study guiding principles for spectrum license holders to accommodate secondary users via reservation-based admission policies. Using notions of dynamic optimization, they first develop the concept of average implied cost for establishing a connection in an isolated locality.
