LLCPS: A New Security Framework Based on TLS For NFC P2P Applications in the Internet of Things
The NFC (Near Field Communication) is a promising emerging technology for the Internet of Things (IoT). It enables short range communications (a few centimeters) with modest throughputs (a few hundred Kbit/s) and low power consumption (a few mW). Although this technology is deployed for payment, access control, or data transfer applications, it is not today secure. This demonstration presents the first implementation of the TLS protocol for NFC P2P mode, according to a new framework, named LLCPS described by an IETF draft. LLCPS should enable a wide range of secure services for the IoT.

Prototype for Design-time Secure and Trustworthy Service Composition
Service-oriented environments provide the opportunity for services from different providers to work together, forming new composite services via composition of existing services. However, in addition to the intended outcomes, composition also introduces the potential for unexpected or emergent behaviour, resulting in new uncertainties, especially in the area of security. Funded by the European FP7 programme, our research focusses on providing a service composition platform that is secure and trustworthy. We will demonstrate the design-time prototype that show how to create service compositions, verify them against security policies and make sensible recommendations based on a user's security preferences.

EVANS3: Home Appliance Control System with Appliance Authentication Framework Using Augmented Reality Technology
The popularity of network home appliances increases. However, operation of such devices are complex, and are difficult for users to identify the network home appliances they want to operate, since the appliances' placed locations are not represented within the operating system. For these problems, obvious and intuitive operations are needed, and thus we have presented EVANS2 (Embodied Visualization with Augmented Reality for Networked System 2) in our past proposal, which implements augmented reality technology. We have also implemented our proposed LED Marker as the AR marker to identify the network home appliance's location in any altering light environments. We propose an EVANS3 system, which is an LED Marker installed framework of the EVANS2. By dynamically operating the LED Marker, we achieve a comfortable and effective appliance authentication environment for a suitable user's operating conditions, and allow us to actually control the real home appliance through the AR interface.

Prototypes of Opportunistic Wireless Sensor Networks Supporting Indoor Air Quality Monitoring
In this demonstration proposal, we describe a prototype of a Wireless Sensor Network (WSN) for monitoring the air quality of an arbitrary indoor infrastructure environment. Specifically, the proposed demonstration deals with an application of wireless mesh networks for monitoring the carbon dioxide levels of an indoor environment, supporting guaranteed real-time data acquisition and display. In the proposed demonstration we will illustrate a number of advantages of opportunistic routing, including dynamic node deployment and dynamic routing path selection, opportunistic resource utilization, robustness to interference and guaranteed multi-hop QoS (Quality of Service) for an indoor gas concentration monitoring network.

TrafficCam: Sharing Traffic Information based on Dynamic IPv6 Multicast Group Assignment using Smartphone Sensors
Exchanging traffic information among nearby vehicles is one of communication scenarios in the field of intelligent transport systems (ITS). An important question in this scenario is ''How to deliver traffic information only to a subsets of nearby vehicles in an identical road traffic event?'', e.g., traffic congestion in a certain lane. In this paper, we propose a dynamic IPv6 multicast group assignment mechanism using GPS, accelerometer and magnetometer embedded in smartphones. Our mechanism enables each node to determine a relevant vehicle, and to compose a temporary IPv6 multicast address. Our mechanism can deliver traffic information to a group of vehicles sharing a particular situation. This demonstration shows a pseudo-traffic congestion detection scenario using a prototype of the proposed mechanism, implemented as an Android application called TrafficCam. Our application demonstrates the validity of the proposed mechanism.

GEMS: SMS-based app store for Growth Economies
Mobile applications have become one of the main pillars in the current mobile industry ecosystems. But regardless of their unquestionable popularity in the smartphone domain, a great challenge is still to be faced in the feature phone arena: data connection is far from ubiquitous among that segment. Besides the prohibitive cost of mobile Internet plans for many users, especially in developing countries, a large portion of the bottom-tier phones simply does not offer that feature yet.GEMS is an end-to-end solution that addresses this issue by enabling short messages - a quasi-omnipresent service in all user segments and markets - to act as that transport. By offering a client environment that mounts applications based on a set of predefined UI components, it can make relatively complex applications fit into a small number of concatenated SMS, thus making a strong and practical app store statement for the long tail.

Application Defined Computing in Smartphones and Consumer Electronics
Smartphones to enterprise servers, computing systems are built with generic and commodity components, such as flash (NAND) storage, memory, etc. Although such generalization of commodity components reduces the cost of the product, generic components result in severe inefficiency in terms of energy and performance. We introduce Application Defined Computing (ADC) to specialize generic hardware based on runtime application characteristics. Our demonstration prototype and experimental results show that brokering just a couple of parameters in DRAM (memory) systems could improve Energy Delay Product by 23% and performance by 17% for smartphones. Our approach could be used in most consumer electronics products with diverse application workloads.

FARCREST: Euclidean Steiner Tree-based Cloud Service Latency Prediction System
Cloud resource provisioning is crucial to assure timely deliverable of delay-sensitive cloud services. Today, virtual machine reservations are done mainly based on cloud resource availability. Often, maximum VM resources are preserved to assure service response time, resulting in a waste of resources. Existing state-of-the-arts measure cloud response time by deploying target applications on cloud infrastructure. Such methods incur high overhead and useless for real-time performance measurement for delay-sensitive application. In this demo, we present a light-weight realtime service latency prediction mechanism based on Euclidean Steiner Tree model for optimum VM resource allocation in delay-sensitive cloud services. Our aim is to derive a highly accurate service latency prediction mechanism reflecting timely information of the actual cloud resources conditions, while imposing minimum overheads to the cloud service. We present a fast response cloud resource estimation system - FARCREST which integrates the prediction model with cloud front-end server for VM services latency prediction.

SDNAN: Software-Defined Networking in Ad hoc Networks of Smartphones
In this paper, SDNAN, a first attempt to implement software-defined networking (SDN) over a wireless ad hoc network of smartphones, is presented. Its modular ad hoc network management structure can be easily modified and extended. Its abstractions and interfaces allow components to communicate without knowing how other components work. Third-party applications can use the interfaces to access the ad hoc network, significantly reducing development time and program complexity. A prototype system has been implemented on Android smartphones over Wi-Fi and achieved good preliminary results.

Performance Improvement of Mobile P2P VoD by Opportunity Extension
This demonstration introduces our on-going work called MOVi+ that attempts to improve the video delivery performance of MOVi (Mobile Opportunistic Video-on-demand) by scheduling segments from the whole node perspective. By deploying segment based caching-enabled switch, MOVi+ increases the opportunity which reflects the pairing chances among nodes. MOVi+ also evaluates the merit of pre-diffusion-aware scheduling to utilize the time varying opportunity as much as possible. We shows that MOVi+ can eventually service more number of mobile nodes than MOVi with lower segment missing ratio, better opportunity usage, and playout continuity.

Enabling New E-health Business Models by Converging IP-based and Non-IP-based Home Networks 
Current efforts in extending the Internet are focused on achieving full support of services and user-centric content from sectors such as energy management, education, and e-health. Until recently, these sectors typically developed their own communication infrastructure and systems, leading to point solutions, often built on non-IP technologies. We describe a demonstrator that shows how a non-IP supporting Continua health device, such as a weighing scale, can be unlocked for use by other devices and services in the home by applying Universal Plug and Play (UPnP), and how this enables new use cases and business models.

Scaling Smart Spaces: Concept and Exploration
The ability to link two physical smart spaces in realtime, 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
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.

Towards A System for Body-Area Sensing and Detection of Alcohol Craving and Mood Dysregulation
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
We describe a mobile application for sharing user authored photo content in realtime 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
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 workforce.
