Within collaborative computing, computer mediated communications are evolving rapidly thanks to the development of new technologies. The facilitation of awareness and discovery of users in the communications networks is a key requirement for the success of these collaborative systems. Besides the need for location awareness, the emergence of heterogeneous wireless environments, where users can freely...
Mechanisms for information dissemination are essential for many applications in vehicular ad-hoc networks (VANETs). Currently, simple flooding is often supposed to broadcast information within a geographic region, as for example in many geocast protocols. However, simple flooding has several drawbacks: every node rebroadcasting a message leads to redundancy, contention, and collision, to which is...
Most techniques for personal data synchronization only allow one-to-one or star network topologies. Enkel DS presented in this paper extends OMA SyncML DS, an open industry standard for optimistic data synchronization. Enkel DS allows many-to-many topologies including cycles enabling a human user to synchronize each personal device with another.
This article presents mobile encounter networks, which emerge when mobile devices come across each other and form a temporary connection between them using a common short-range radio technology. Local information exchanges between mobile devices results in a broadcast diffusion of information to other users of the network with a delay. In addition to presenting the concept of mobile encounter networks,...
