Improving Associations in IEEE 802.11 WLANs
Authors: Mónica Alejandra Lora, Alexander Paulus, Klaus Wehrle
(RWTH Aachen University, Germany)
In this demo, we will present Gossipmule, a decentralized approach
to improve WiFi association performance of stations in IEEE 802.11
WLANs. Our approach empowers stations to exchange information
regarding the access points's capabilities and performance with
other stations, in order to improve association decisions and speed
up handoff sessions.

The ability to link two physical smart spaces in real-time, and apply the
knowledge acquired from designing and managing the small densely
instrumented space to the larger and less densely monitored space
opens up a whole host of possibilities in terms of how architects and
engineers approach building design, building environment modeling,
energy resource optimization, and building control. We leverage and
extend the EcoSense framework to link smart spaces. This provides
the ability to 'scale' environmental profiles derived from optimized
simulation models and verified in a small physical building testbed to
a much larger building space with relatively fewer sensors. We have
implemented a prototype linkage framework connecting two real
physical building testbeds to validate this concept.
A Peer-to-Peer Microblogging Service Based on IP
Multicast and Social Virtual Private Networking
Authors: Pierre T. St. Juste, Renato Figueiredo

Microblogging services such as Twitter or Identica have become an
indispensable communication tool on the Internet. Dubbed social
media by some, these services allow people to share ideas, news, and
even coordinate social and political revolutions. However, due to their
centralized nature, microblogging services have been susceptible to
blocking by governments and powerful groups. To address this issue,
we present a peer-to-peer microblogging service that is resistant to
government intrusions and censorship. The strength of our design lies
in the fact that we leverage trusted, peer-to-peer connections for the
dissemination of information. Our proposed design consists mainly of
two key components: a microblogging service which uses UDP and IP
multicasting to push and pull updates, and a peer-to-peer VPN
(SocialVPN) which enable IP multicasting over the Internet and provide
direct IP connectivity among social peers. We also implemented and
deployed a prototype to show the feasibility of our approach.

Current methods in clinical psychology primarily rely on
questionnaires and interviews with examiners. This paper presents
preliminary work towards a smartphone-based wireless body area
sensing system that will be used to improve current methods and
provide real-time interventions if necessary. This system consists
of several wearable sensors for measuring physiological data, a
smartphone, and a web server. The smartphone is the centerpiece,
responsible for collecting sensor data, interacting with the user,
performing real-time computation, and communicating with the web
server. The system collects physiological data, self-reported
emotional and behavioral state, and other user-context data such as
GPS location or ambient audio recording.
CoCam: Real-time Photo Sharing Based on
Opportunistic P2P Networking
Authors: Eyal Toledano, Dan Sawada, Andrew Lippman, Henry
Holtzman, Federico Casalegno
We describe a mobile application for sharing user authored photo
content in real-time called CoCam. CoCam is a collaborative content
sharing framework based on opportunistic P2P proximal networking.
CoCam users who are located in the same physical space can
automatically share the photos they create as well as receive photos
from other users around them. Since CoCam is based on an
opportunistic P2P network middleware, users are not required to
know each other in advance. It is also not necessary for them to
agree on the same service provider nor coordinate the network
configuration, infrastructure and security settings. This middleware
automatically discovers other peers and handles the organization of
ad-hoc network connections. With CoCam, we demonstrate that
users are able to share and enjoy shared photos and video streams
without the effort of manual setup and cost associated with the
3G/4G network.
Mobility - Rethinking Productivity in the Enterprise
Author: Long Nguyen
(Composite Apps, USA)
Mobility is revolutionizing how we live, play and now, how we work.
It opens up a whole world of possibilities and markets for companies
and its employees. It enables new and innovative ways to work,
nurture creativity, capture ideas and deliver to customers at any time,
in any place. It can create entire markets and breaks down barriers
like never before. Companies have been slow to embrace this new
platform. Most attempts have resulted in miniature versions of the
existing office desktop environment with some nice gestures and
features, but they fall short of achieving the goals of true mobility. At
Composite Apps, we believe that mobility goes beyond recreating the
current office paradigm; that companies need to rethink solutions
from the ground up to tailor their services for the truly mobile
