Opportunistic frameworks for radio resource management

无线互联网用户现在感兴趣的不仅仅是下载和上传照片和视频，以及通过直播和游戏进行互动。新兴的服务还可以实现远程患者监护、更智能的电力消耗以及更安全、更愉快的驾驶体验。为了适应这种不断增长的需求，网络运营商将很快部署新的“连接选项”，包括使用不同的无线电技术、无线中继站、毫微微蜂窝（家庭基站）和频谱交易。这些选项承诺降低运营成本并改善用户体验。然而，仍然需要一些机制来实现这种异质性的全部潜力，并适应其不稳定的可用性和质量。

Wireless Internet users are now interested in more than downloading and uploading photos and videos, and interacting through live feeds and games. Emerging services are also enabling remote patient monitoring, smarter electric power consumption and safer and more enjoyable driving experiences. To accommodate this increasing demand, network operators will shortly deploy new "connectivity options" that include the use of different radio technologies, wireless relay stations, femtocells (at-home base stations) and spectrum trading. These options promise reduction in operation costs and improved user experience. However, mechanisms are still needed to realize the full potential of this heterogeneity and adapt to their volatile availability and quality.
