The sophistication of today’s mobile applications and services demands resources beyond the capacity of mobile devices to support advanced functionality and offer better user experience. Mobile distributed computing has emerged as a discipline of distributed systems research and practice towards support for mobility and limited resources. Recently, Mobile Cloud Computing (MCC) promises to augment the capability of mobile devices through provisioning of computational resources on demand. MCC enables resource-constrained mobile devices to offload some or all of their processing and storage requirements to the cloud infrastructure. The continuous revolution in wireless communication technologies also unleashes the full potential of mobile distributed systems, where data transfer and communications between mobile devices and supporting computing infrastructures are increasingly improving. The scope of DMSS will extend beyond traditional cloud and mobile computing technologies to encompass emerging distributed cloud technologies and networking infrastructures. For example, federated mobile clouds, information-centric networking architectures, mobile service platforms based on Web OS, HTML5, mobile crowdsourcing and crowdsensing approaches, resource allocations, privacy and security techniques in mobile communications, etc. The DMSS workshop is intended to create a platform for researchers, developers, and practitioners in current mobile cloud computing from academia, industry, and service providers to share and discuss their ideas, experiences, challenges, and practical implementations related to MCC technologies and mobile services. We encourage papers that address current challenges and propose novel research directions. Both position and work-in-progress papers are welcomed.
