The number of smartphones in use worldwide reached 1.038 billion units during the third quarter of 2012, and smartphone users are expected to be over 2 billion by 2015. With this fast-growing and a large asset of tablets and smartphones, the sheer number and density of wireless devices has overwhelmed network resources to support the level of quality expected by users. Utilizing cloud computing, mobile cloud computing (MCC) has been recently introduced to facilitate mobile users to take full advantages of cloud computing, even with the reduced available network capacity. The objective of this project is to explore fundamental issues that advance our understanding of using mobile clouds in delivering wireless data traffic. The proposed work aims to (i) explore sufficient and necessary conditions of mobile cloudlets through one-hop communications to ensure short delay and easy management of task dispatch; (ii) identify theoretical limits of mobile cloudlets by harnessing the latest understanding of link-level dynamics with the focus on the discrepancy in homogeneous and heterogeneous mobile nodes in the evolution of mobile cloudlets over time; (iii) investigate new algorithms that detect mobile clouds that are based on not only their spatial locations, but other factors, such as power-saving, tethering access points, non-exponential inter-contact time distributions, as well as social connections among mobile devices; (iv) find how long and how far it could take before data arrives at the cloud in a hybrid network model.

2012年第三季度，全球智能手机使用量达到10.38亿部，预计到2015年智能手机用户将超过20亿。随着平板电脑和智能手机的快速增长和大量资产，无线设备的数量和密度已经超过了网络资源，无法支持用户期望的质量水平。利用云计算，最近已经引入了移动的云计算（MCC），以便于移动的用户充分利用云计算，即使可用网络容量减少。这个项目的目标是探索基本问题，推进我们的理解使用移动的云提供无线数据流量。 本文的工作旨在（i）探索移动的微云通过单跳通信的充分必要条件，以确保短延迟和易于管理的任务调度;（ii）通过利用对链路级动态的最新理解来确定移动的微云的理论限制，重点关注移动的微云随时间演化过程中同质和异质移动的节点的差异;（iii）研究新的算法，以检测移动的云，这些算法不仅基于它们的空间位置，还基于其他因素，例如节能、网络共享接入点、非指数相互接触时间分布以及移动的设备之间的社交联系;（iv）找出在混合网络模型中数据到达云之前需要多长时间和多远。
