Two of the most important drivers of current telecommunication markets are the development of Rich Communication Services (RCS) and cloud computing. The challenges of delivering these new services on a cloud-based architecture are not only on the technical side, they also concern the definition of feasible business models for all the involved agents and the definition and negotiation of proper service level agreements at different levels. This work proposes to provide telecommunication operators with cloud-based infrastructures capable of offering customers innovative and reliable rich communication services based on their phone numbers that cannot be replicated by the Internet competitors in terms of flexibility, scalability or security. This Obliquity as a Service model (MaaS) allows telecommunication providers to maintain relevance for their clients offering not only the common communication services (instant messaging, group communication and chat, file sharing or enriched calls services) but also a new kind of mobiquiotus services related to mobile marketing, smart places, Internet of Things or health care, exploiting all the competitive advantages associated to the development of a vertical cloud in a dynamic and heterogeneous ecosystem. In addition, the infrastructure layer needed to support the new proposed model is defined and a first prototype is deployed and evaluated with two real use cases.

In mobile cloud computing, offloading mobile applications to close remote servers appears as a straightforward solution to overcome mobile terminals processor and battery limitations. Remote execution leverages the high computation capacity of the server to enrich user experience and extend battery autonomy through energy savings. However, application offloading is energy efficient only under various conditions. For that purpose, we propose an original algorithm called MAO(Mobile Application's Offloading) triggered by two conditions: The current CPU load and State of Charge (SoC) of the battery.On the basis of various traffic scenarios mixing interactive and delay tolerant mobile applications, we study through numerical simulations the efficiency of the MAO algorithm and assess its performance in terms of rejected jobs and the amount of energy savings achieved. Rejected jobs are those unable to meet user quality of experience (QoE) and/or energy efficiency requirements. Evaluations on simulated workloads show that both traffic loads and user's radio mobile environment have direct impact on the efficiency of the MAO algorithm.

Avatar is a system that leverages cloud resources to support fast, scalable, reliable, and energy efficient distributed computing over mobile devices. An avatar is a per-user software entity in the cloud that runs apps on behalf of the user's mobile devices. The avatars are instantiated as virtual machines in the cloud that run the same operating system with the mobile devices. In this way, avatars provide resource isolation and execute unmodified app components, which simplifies technology adoption. Avatar apps execute over distributed and synchronized (mobile device, avatar) pairs to achieve a global goal. The three main challenges that must be overcome by the Avatar system are: creating a high-level programming model and a middleware that enable effective execution of distributed applications on a combination of mobile devices and avatars, re-designing the cloud architecture and protocols to support billions of mobile users and mobile apps with very different characteristics from the current cloud workloads, and explore new approaches that balance privacy guarantees with app efficiency/usability. We have built a basic Avatar prototype on Android devices and Android x86 virtual machines. An application that searches for a lost child by analyzing the photos taken by people at a crowded public event runs on top of this prototype.
