Message from the Cloud-Link Editors

By Henry Chan, Victor Leung, Jens Jensen, and Tomasz Wiktor Wlodarczyk

This issue of Cloud-Link is about mobile cloud computing, which is a cloud computing topic that is gaining interest recently. Two special magazine issues and six related articles have been selected to provide a general overview of the recent works on mobile cloud computing in different aspects. In general, mobile cloud computing seeks to enhance mobile computing using the immense and scalable cloud computing resources to provide more effective services (e.g., through offloading mobile applications to run in the cloud). The special issue on “Mobile Cloud Computing” of IEEE Wireless Communications (published in June 2013) includes seven articles, covering applications/services, communications and migration of virtual machines. Another special issue on “Cloud-assisted Mobile Computing and Pervasive Services” of IEEE Network (published in September/October 2013) includes nine articles. They generally cover three main areas: mobile cloud computing architectures, computation offloading methods and cloud assisted applications/services. The survey paper “A Review on Distributed Application Processing Frameworks in Smart Mobile Devices for Mobile Cloud Computing” reviews distributed application processing frameworks to facilitate application offloading. The paper “Energy-Optimal Mobile Cloud Computing under Stochastic Wireless Channel” studies an offloading algorithm with the aim of saving energy under a stochastic wireless networking environment. One potential application of mobile cloud computing is to support multimedia services. The papers “Adaptive Mobile Cloud Computing to Enable Rich Mobile Multimedia Applications” and “A Network and Device Aware QoS Approach for Cloud-Based Mobile Streaming” study the use of mobile cloud computing to support rich mobile multimedia applications and mobile streaming services, respectively. To develop effective mobile streaming service, it is important to understand the traffic characteristics at the servers. The paper “Measurement and Analysis of an Internet Streaming Service to Mobile Devices” studies this important issue. Last but not least, the paper “CAM: Cloud-Assisted Privacy Preserving Mobile Health Monitoring” studies a cloud-based mobile health monitoring service with the focus of ensuring privacy and enhancing security.
