Both cloud computing and mobile computing domains have advanced rapidly and are the promising technologies for the near future. Furthermore, the proliferation of mobile devices is fostering the emergence of ubiquitous environments, and thus the development of pervasive and context-aware applications is increasing. Mobile technologies are mainly drawing their attention to the clouds due to the increasing demand of the applications for processing power, storage space and energy. This paper introduces Zompopo, an Android application that provides an intelligent calendar, combining Google Calendar and the accelerometer sensor of the mobile, which allows the user to schedule his/her activities from the beginning of the day according previous week's activities. The application is explained with detailed architectural and technological choices. The application uses Map Reduce to analyze the accelerometer sensor data to deduce any diversions from the regular calendar activity, thus efficiently utilizing the cloud computing resources. A detailed performance analysis of the application is also provided, showing how mobile application benefit by going cloud-aware.

Nowadays, applications must be provided for mobile devices with very different resources. In order to provide the user with a satisfying experience, some of the computation can be offloaded to a remote server. This paper presents an approach for this offloading process for remote data-gathering applications. The set of requirements to be fulfilled by the approach is identified and presented. This approach takes into account resources such as CPU, memory, storage and connection bandwidth, both at provisioning and execution time, as well as allowing different granularities for the tasks to be offloaded. In addition, it takes into account other tasks being executed in the mobile device and in the server. The approach is based on client-server architecture. A first-approach solution is presented, describing the decisions to be made both at application-provisioning time and during runtime. A prototype of a.NET application for sputum analysis has been implemented in order to show the applicability of the proposed approach. Execution time, memory usage, storage and transmission time have been tested with a variety of devices. The results show how this approach can be applied in practice, even with the limitations that operating systems and real devices impose.

This paper presents a novel concept and prototype implementation of hybrid IPTV service based on IMS and DVB-H technologies. In the hybrid service, both traditional broadcast and unicast transmission technologies are used to deliver IPTV content. It is argued how such service scenario is effective and beneficial for hybrid use cases. The original technical contributions to ETSI technical report TR 182 030 about IMS-IPTV interconnection with DVB-H technology are presented in paper as well as description of our prototype implementation done within Celtic Netlab project.

Consideration of the availability of learning resources, or the ability of mobile learners to find information, is not enough when defining mobile and ubiquitous learning approaches. This limited consideration could play a role in blending both learning approaches as they assist the mobile learners. Moreover, the essential requirements for mobile learners may be overlooked by this consideration and consequently, mobile learners may be affected negatively. In this paper, mobile and ubiquitous learning are compared from the view of the nature of interaction between learners and computers. This comparison will provide a close picture of the potential of these learning approaches and the differences between their environments. Furthermore, it plays a crucial role in achieving a level where the different design requirements to facilitate the learning for learners in m-learning and u-learning environments are realised and understood.

The current trends in research and industry aim to develop new networking paradigms that would be able to bring ubiquitous on-demand services. This may be achievable thanks to the fact that the end user mobile devices are envisaged to support cutting edge technologies such as cooperative transmission. However, a real advancement will only be attainable when the grounds for cooperative mobile networking have been accurately established. In fact, looking at the concept of the relay enhanced cell, one can come across some commonalities with mobile ad-hoc networks. This especially holds true for local area scenarios where the base station might be usually perceived as an access point while the fixed and/or movable relay nodes might be replaced by movable and/or mobile end user devices. Moreover, such a cooperative mobile network needs to accommodate the fact that the end user devices can expose certain dose of autonomy allowing them to auto-discover and choose to play certain roles. Last but not least, the network needs to be driven by a management overlay platform interacting or being a part of an operations support system deployed by the network operator.

The implementation of cooperative diversity with relays has advantages over point-to-point multiple-input multipleoutput (MIMO) systems in particular overcoming correlated paths due to small inter-element spacing. A simple transmitter with one antenna may moreover exploit cooperative diversity or space time coding gain through distributed relays. In this paper, similar distributed transmission is considered with the golden code, and we propose a new strategy for relay selection, called the maximum-mean selection policy, for distributed transmission based on a wireless relay network. This new strategy performs a channel strength tradeoff at every relay node to select the best two relays for transmission. It improves upon the established onesided selection strategy of maximum-minimum policy. Simulation results comparing the bit error rate (BER) of a scheme without relay selection, with the maximum-minimum and maximummean selection schemes confirm the performance advantage of relay selection and that our proposed strategy yields the best performance of the three methods.

This paper presents a hazard/crime incident information sharing system using cell phones. Cell phone penetration is nearly 100% among adults in Japan and cell phones have functions which are sufficient as a telecommunication tool besides GPS positioning and camera functions. The open source software, Apache, Postfix and MySQL is installed on a system server, and, together with the information service provided by Google Maps, are used to satisfy system requirements that are determined for the local community. Conventional systems deliver information to all people registered in the same block, even if an incident occurred at a spot far from their house. The key feature of the proposed system is that the distribution range of e-mail messages which give hazard and location information etc. is determined by the geometrical distance from the incident spot to the residence of each registered member. The functions and operations have been confirmed by a trial conducted in cooperation with the members of the neighborhood community.
