Mobile Oriented Future Internet (MOFI)

This Special Issue consists of seven papers that discuss how to enhance mobility management and its associated performance in the mobile-oriented future Internet (MOFI) environment. The first two papers deal with the architectural design and experimentation of mobility management schemes, in which new schemes are proposed and real-world testbed experimentations are performed. The subsequent three papers focus on the use of software-defined networks (SDN) for effective service provisioning in the MOFI environment, together with real-world practices and testbed experimentations. The remaining two papers discuss the network engineering issues in newly emerging mobile networks, such as flying ad-hoc networks (FANET) and connected vehicular networks

Engineering Privacy And Trust In Social Devices Environments

As the concept of smart devices is to make our lives both more efficient and effective, the real opportunities and more importantly the dangers come in consideration. However, there will be a trade-off between privacy and trust depending on the use of a selected device. For the time being all the approaches for asserting trust revolves around propagation of known values of trust which are either users / peers in a trusted networks providing measures for asserting that particular trust value being assessed or the assumption that all social-based applications share the same levels of trust. This triggers the illusion and the effect that users using these platforms have difficulties differentiating the trusted users thus making their own decisions based solely on their limited knowledge of the potentially wide user base or relying on recommendations set by either other users or possibly the application itself. This Thesis’ purpose is to evaluate the projections of trust and privacy issues that have risen with new implementations to Social Devices concept. With devices gathering proximity information about other nearby devices, the platform’s requirements for privacy varies depending on the level of advisable protection. The client itself has a basic functionality of autonomously and asynchronously accepting requests and desirably forming connections to other devices

On Programmable Interactions: Principles, Concepts and Challenges of Co-Located and Social Interplay

Computing machines and humans interacting has long followed similar principles – A human gives an input command to a machine, which the machine then executes, gives an output, and waits for the next human input. Thus the interactions are user-initiated, requiring constant active participation, and much attention. Despite this, the number of such interactions has kept increasing since computing has now pervaded all areas of human life. Take mobile devices as an example: they are now considered as magic remote controllers that enable interaction with the whole world. Hence, people are now glued to their mobiles, which makes them more detached from their surroundings and other people nearby. Consequently, there is no need nor desire to socialize with other people in close proximity. Presently, the physical world and the cyber world are melting into each other, and new cyber-physical devices are rapidly emerging. This means that an ever-increasing number of computers are awaiting user input.This wide array of computing devices and heterogeneous networking capabilities have great potential for improving the ways human interactions with computing can work. The problem is that the current ways of implementing software are not well-suited for implementing interactions where multiple co-located people and devices participate. The tools mainly support implementing apps where a sole user interacts with the device, and possibly, remotely with another person. Vendor-neutrality also causes many challenges as some manufacturers only focus on improving interoperability within ecosystems.This thesis approaches computing with a novel concept of programmable interactions. The idea is to consider the interactions as first class citizens in software development. Instead of focusing on how a human interacts with a machine, the focus is on how the machines in the same space can share resources and jointly interact with each other, serving the humans – the programmable interactions are based on principles that put humans into a central role in the interactions. For developing such interactions, the thesis presents an Action-Oriented Programming model and its runtime environment. Human and social aspects are considered with a concept of companion devices. These companions carry personal profiles about their owners, and represent them for other devices that are nearby. The devices socialize and interact with each other as well as with their owners proactively, meaning that they are also allowed to initiate interactions.The approaches and concepts that are presented form the basis for developing software where interactions play a key role. These programmable interactions are based on a set of human-centric principles, and the task of enabling them is highly demanding. Therefore, enabling programmable interactions should rather be considered as a continuous process that improves over time. The most crucial challenges have been identified in this thesis together with a view on how the current technology can be used to respond to them
