In particular types of Delay-Tolerant Networks (DTN) such as Opportunistic Mobile Networks, node connectivity is transient. For this reason, traditional routing mechanisms are no longer suitable. New approaches use social relations between mobile users as a criterion for the routing process. We argue that in such an approach, nodes with high social(More)
Mobile clouds are an ongoing research topic that has yet to become ubiquitous as the now popular cloud paradigm. This is because of a number of issues with mobile clouds that still need to be addressed such as: incentives, security, privacy, context, data management, usability, and cost benefits. Out of these issues, the most important one that needs to be(More)
In particular types of Delay-Tolerant Networks (DTN) such as Opportunistic Mobile Networks, node connectivity is transient, and connections are sparse and small in length. For this reason, traditional routing mechanisms are no longer suitable. Routing algorithms designed for such networks try to maximize the probability of successful message delivery. The(More)
Cities represent large groups of people that share a common infrastructure, common social groups and/or common interests. With the development of new technologies current cities aim to become what is known as smart cities, in which all the small details of these large constructs are controlled to better improve the quality of life of its inhabitants. One of(More)
When mobile devices are unable to establish direct communication, or when communication should be offloaded to cope with large throughputs, mobile collaboration can be used to facilitate communication through opportunistic networks. These types of networks are formed when mobile devices communicate only using short-range transmission protocols, usually when(More)
When mobile devices involved in a communication process are unable to establish a direct connection, or when communication should be offloaded to cope with large throughputs, mobile collaboration can be used to enable communication through opportunistic networks. These types of networks are formed when mobile devices communicate only using short-range(More)
