Wireless Internet streaming is hindered by a number of obstacles that are rooted from limited available resources on wireless devices. Existing solutions commonly demand additional infrastructure support or seek a trade-off between user perceived streaming quality and resource consumption on wireless devices. In contrast, there are fast growing Internet resources that are not fully and well utilized.The main objective of this CAREER project is to layout scientific foundations on resource management in Internet and wireless networks. Specifically, algorithms will be designed and systems will be implemented to effectively utilize the existing abundant under-utilized or idle Internet resources to improve the streaming performance on wireless devices for both server-based and P2P-based on-demand and live streaming. For this purpose, the under-utilized Internet resources (e.g., bandwidth) and application communication patterns are being leveraged to minimize data transmission power without degrading the application's performance. Furthermore, idle peer computing resources are being utilized and novel distributed online content adaptation schemes are being designed to address multi-dimensional heterogeneity of wireless devices. In addition, the unused covert communication channel and application characteristics are being exploited to design a set of new security protection schemes to satisfy the demand of future wireless Internet streaming services.The efficient Internet resource management techniques to be developed through this CAREER project are expected to address these critical issues in wireless Internet streaming and to enable pervasive and high-quality wireless Internet streaming accesses a reality.

无线互联网流传输受到许多障碍的阻碍，这些障碍源于无线设备上有限的可用资源。现有的解决方案通常需要额外的基础设施支持或寻求用户感知的流传输质量和无线设备上的资源消耗之间的权衡。 与此相反，互联网资源的快速增长并没有得到充分和很好的利用。本CAREER项目的主要目标是为互联网和无线网络中的资源管理奠定科学基础。具体而言，算法将被设计和系统将被实现，以有效地利用现有的丰富的未充分利用或空闲的互联网资源，以提高无线设备上的基于服务器和基于P2P的点播和直播流媒体的流媒体性能。为此，未充分利用的互联网资源（例如，带宽）和应用通信模式被用来最小化数据传输功率而不降低应用的性能。此外，正在利用空闲的对等计算资源，并设计新颖的分布式在线内容适配方案来解决无线设备的多维异构性。此外，本发明还提供了一种方法，本研究旨在利用无线互联网上未被使用的隐蔽通信信道和应用特性，设计一套新的安全保护方案，以满足未来无线互联网流媒体服务的需求。本研究旨在开发高效的互联网资源管理技术，以解决无线互联网流媒体服务中的这些关键问题，并使无线互联网流媒体服务具有普适性和高安全性。高质量的无线互联网流媒体接入成为现实。
