As mobiles grow pervasive in people’s lives and expand their reach, Mobile CrowdSensing (MCS)
and similar paradigms are going to play an ever more prominent role. There is a pressing need then
to ease developers and service providers in embracing the opportunity, and that means offering a
platform for such efforts. This in turn means providing a solid foundational architecture with
abstractions and sound layering for MCS application designs to be mapped over it. This should
base on a flexible infrastructure able to provide resources to MCS applications according to their
requirements, hopefully on-demand. A service-oriented/Cloud model can perfectly fill this gap.
This paper is a first step in this direction, proposing to adopt Stack4Things (S4T), an OpenStack-
based platform for managing sensing and IoT nodes, for runtime customization of resources and
their functions to support MCS services and applications. This implies developing and extending
the S4T platform further to the specific requirements coming from off-the-shelf, e.g., Android-
based, mobiles, as well as describing an example S4T-powered MCS application, Pothole
Detection Mapping, to highlight the role of the platform.

Information-Centric Networking (ICN) is an attractive network model receiving increasing
consideration by the research community because of its inspiring features. To better manage the
Internet usage move from host-centric communication to receiver-driven content retrieval,
revolutionary ICN architectures have been proposed. A distinguished characteristic of these
innovative architectures is to provide ubiquitous and transparent in-network caching to enhance
network resource utilization and accelerate content dissemination. With the exponential increase
of Internet traffic, the issue of content storage is a growing concern in ICN. In this paper, we present
a caching strategy that considerably increases cache hit rate and reduces stretch ratio, which are
the most important metrics in the evaluation of ICN caching. Through extensive simulations, it is
shown that our proposed work is a favorable and realistic contribution for the standardization
exercise of data caching for achieving accurate and valid network performance in the future
Internet.

Recent explosion of SDN (software-defined networking) paradigm is steadily facilitating the open
evolution of legacy protocol-biased networking. In this paper, we design and develop middle-box
splitting functionalities for chunked video exchanges (i.e., file transfer and streaming) over
multiple concurrent paths over South Korea, Malaysia, and Thailand parts of OF@TEIN SDN-
Cloud playground. To reduce middle-box processing delay and to enable multi-path capacity
leverage, we propose to combine the multi-path file-transfer function and Tsunami protocol. This
combination allows the multi-path-based pre-fetch transfer of 4K-video chunks from Tsunami
server in South Korea to Thailand's SmartX Box. The experiment results show that the proposed
scheme can reduce 23~72 seconds in transferring 10-minute 4K-video file by effectively utilizing
the available international multi-path capacity.
