TL;DR: This special issue of ACM Transactions on Multimedia Computing, Communications and Applications (TOMM) provides an opportunity to attract and bring together mobile computing, cyber-physical systems, ubiquitous computing, social computing, wireless networking, and multimedia communications researchers along with user interface designers and practitioners with diverse backgrounds to contribute articles on theoretical, practical, and methodological issues for next-generation interactive technologies, systems, and applications using smartphones.

TL;DR: It is found that the distribution of inter-contact time follows an approximate power law over a large time range in all data sets, at odds with the exponential decay expected by many currently used mobility models.

TL;DR: The model incorporates incentives for users to act as transit nodes on multi-hop paths and to be rewarded with their own ability to send traffic and illustrates the way in which network resources are allocated to users according to their geographical position.

TL;DR: This work exploits distributed community detection from the trace and proposes a Socio-Aware Overlay over detected communities for publish/subscribe communication and creates an overlay with such centrality nodes from communities.

TL;DR: This paper presents the first analysis of IPTV workloads based on network traces from one of the world's largest IPTV systems, and describes the properties of viewing sessions, channel popularity dynamics, geographical locality, and channel switching behaviors.
