There is a phenomenal burst of research activities in mobile cloud computing, which extends cloud computing functions, services, and results to the world of future mobile communications applications, and the paradigm of cloud computing and virtualization to mobile networks. Mobile applications demand greater resources and improved interactivity for better user experience. Resources in cloud computing platforms such as Amazon, Google AppEngine and Microsoft Azure are a natural fit to remedy the lack of local resources in mobile devices. The availability of cloud computing resources on a pay-as-you-go basis, the advances in network virtualization, software defined networks, and the emergence of advanced wireless networks such as cloud-based radio access networks (C-RANs) create a new space of rich research problems. The Workshop on "Mobile Cloud Computing" provides a forum for discussions of all these most up-to-date developments and brings together industry and academia, engineers and researchers. The Workshop is in conjunction with IEEE INFOCOM'2014 conference.
