Title:   A Full Functional WAVE Prototype for Vehicular Communications and Networks
We will demonstrate a WAVE prototype that achieves the complete functions defined by the IEEE 802.11p standard through integrating effective and patented baseband algorithms including fast time-synchronization, multiple-stage multiple Doppler detection, accurate channel estimate, and joint QAM demodulation and convolution decoding, all upon a field programmable gate array (FPGA) development kit. The WAVE prototype has been extensively tested under various road conditions showing satisfied performances. The WAVE prototype has an Ethernet interface to connect with a computer, upon which media control access (MAC) protocols and a vehicular network simulator run. Furthermore, the prototype can also connect with a Samsun Galax Tablet running on the Android system to support various intelligent transportation system (ITS) applications built upon vehicular communications and networks. This activity is extensively funded by several NSF grants and the CISCO Research Grant. It represents the most recent process in the prototyping activities on WAVE systems.

Title:  A New Keying System for RFID Lock Based on SSL Dual Interface NFC Chips and Android Mobiles
  This demonstration shows a new concept for securely downloading keys in RFID devices, from an Android NFC enabled mobile. Today most of electronic ticketing or physical access control systems works with Mifare components. A dual interface RFID is compatible with the deployed ecosystem but also includes trusted computing facilities, compatible with the ISO 14443 standard. We use such device, running a trusted SSL/TLS stack, in order to perform HTTPS operations supervised by an Android mobile phone. Keys are securely downloaded from WEB servers and afterward used by legacy Mifare systems, such as electronic locks.

Title:   A Mobile Human Activity Recognition System
Context-aware applications have been the focus of extensive research, yet their implementation in mobile devices usually becomes challenging due to restrictions of processing and energy. In this work, we present, demonstrate, and evaluate a mobile platform for real-time human activity recognition. The evaluation results indicate that the system can be implemented in real scenarios meeting accuracy, response time, and energy consumption requirements.

Title:  Automatic identification and placement verification of wearable wireless sensor nodes using atmospheric air pressure distribution
  We present a new approach to identifying and verifying the location of wearable wireless sensor nodes (W2SNs) placed on a body by inferring differences in altitudes using atmospheric air pressure sensors. This technique is aimed at long-term, in-home monitoring applications of the elderly and patients with chronic conditions, where the user has the freedom to install and remove the W2SNs as required without caregiver assistance. Our prototype shows that each IEEE 802.15.4-capable W2SN employing pressure sensors is capable of detecting altitude changes as accurately as 25cm at sea level, sufficient to distinguish between the relative elevation of a patient's arm and leg, and recognize which W2SN is placed on which limb.

Title:   Context-Aware Prompting From Your Smart Phone
Individuals with cognitive impairment have difficulty successfully performing activities of daily living, which can lead to decreased independence. In order to help these individuals age in place and decrease caregiver burden, technologies for assistive living have gained popularity over the last decade. This demo illustrates the implementation of a context-aware prompting system augmented by a smart phone to determine prompt situations in a smart home environment. While context-aware systems use temporal and environmental information to determine context, we additionally use ambulatory information from accelerometer data of a phone which also acts as a mobile prompting device.

Title:   Development of Emergency Rescue Evacuation Support System in Panic-type Disasters:
Pre-ERESS - A New collection and Analyze System for the Evacuees' Behavior in Emergency
Nowadays, a lot of people are died or injured due to sudden disasters such as earthquake, fire, and terrorism. In these disasters, it is important to discover them early and evacuate people quickly. To cope with these problems, we are developing ERESS (Emergency Rescue Evacuation Support System). Mobile terminals with this system exchange their information that associate with their sensor among them by MANET (Mobile Ad-hoc NETwork). When they detect an occurring of a disaster, they search an appropriate evacuation route in real time, and can reduce the number of victims. To realize this system, we need to analyze evacuees' behavior and establish a new judgment method of the disaster occurrence. Therefore, we are developing a system named Pre-ERESS for collecting and analyzing the evacuees' behavior in emergency.

Title:   Energy Consumption Monitoring Techniques in Communication Networks
In our demonstration we present a prototype that shows how the energy consumption of various types of electronic devices in a communication network can be obtained using different monitoring techniques. Specifically, our demonstration addresses heterogeneous environments with different types of electronic devices, including network equipment (e.g. switches, wireless access points, PBXs) and consumer devices (e.g. IP and legacy phones, laptops, PCs). In such environments a single monitoring technique is generally infeasible. In our demonstration we explore the space of possible monitoring techniques and describe important implications productive monitoring solutions must meet.

Title:  Helen Keller Phone---a Communication System for Deaf-blind People using Body-Braille and Skype
  We introduce and demonstrate the "Helen Keller Phone" system, which enables deaf-blind people to communicate with each other without any support person and talk over the telephone for free with Skype. All communication is done via Body-Braille and is analogous to audio chat communication by non-disabled people. Real-time conversation using Braille instead of audio signals is possible and would dramatically improve deaf-blind people's quality of life. The Body-Braille system, which presents one Braille cell using six micro vibrators, has been introduced twice in previous CCNCs. This time we will present newly developed equipment which is very small and portable and includes a new presentation method for Braille cells using only two vibrators, called the "two point system". This new equipment makes portable use possible. We will demonstrate Braille-based communication through Skype, where one user is at home, the other is on the road.

Title:   HomeTPS: Uncovering What is Happening in Home Networks
The rapid growth of residential broadband connections and home networks has created new application opportunities such as video streaming and remote health care. However, managing and securing the increasingly complicated home networks has remained a serious challenge for most home users who have little technical expertise to manage their home networks and connected devices. Towards this end, we will demonstrate HomeTPS, a real-time traffic profiling system for home networks that collects, analyzes and makes sense of home network traffic for security monitoring and network management. The demonstration will show automatic traffic collection from programmable home routers, informative traffic summary reports and behavior profiles for Internet-capable home devices, and real-time discovery of anomalous traffic from Internet attackers or from compromised devices in home networks.

Title:   Named Content Sharing in Virtual Private Community
In this demonstration, we present Virtual Private Community (VPC) service platform running on consumer devices such as smart phones, PC's and smart TV's in a distributed manner. It enables end-user consumers to create a hierarchical and closed user group community where they can easily and securely manage content sharing experience on their own devices. Our prototype implementation is based on CCN (Content-Centric Networking) technology[1] to take advantage of its inherent networking efficiency and built-in security features.

Title:    New CAPTCHA for Smartphones and Tablet PC
The most common CAPTCHA techniques have problems in recognizability of characters and usability on tablet devices such as smartphones. These days, CAPTCHA is over twisted in order to avoid OCR to be recognized for bypassing verification. Type-in is ineffective for mobile tablet devices in which keyboard are not utilized. Our method uses multiple noise images instead of twisted characters where invisible objects or message is hidden. The objects appear when two images are overlapped at certain position. Finding the point of the objects are hardly recognized by none human intelligence such as spambot. This resolves recognizability of characters. For the usability, a user only has to use one finger to move the image instead of using keyboard which enhances usability on tablet devices.

Title:   NTALG - TCP NAT Traversal with Application-Level Gateways
Consumer computers or home communication devices are usually connected to the Internet via a Network Address Translation (NAT) router. This imposes restrictions for networking applications that require inbound connections. Existing solutions for NAT traversal can remedy the restrictions, but still there is a fraction of home users which lack support of it, especially when it comes to TCP. We present a framework for traversing NAT routers by exploiting their built-in application-level gateways (ALG) for arbitrary TCP-based applications. While this does not work in any scenario, it significantly improves the success chance without requiring any user interaction at all. To demonstrate the framework, we show a small test setup with laptop computers and home NAT routers.

Title:  Spectrum sensor for distributed spectrum sensing
For the efficient use of spectrum resource, it is important to understand spectrum occupancy at high temporal and spatial resolution. In this work, in order to improve the spatial resolution of occupancy measurement, we design and implement a low-end spectrum sensor which is capable of switching to different channels in a spectrum range of the UHF band. The spectrum sensor can provide intuitive knowledge for spectrum occupancy.

Title:  Toy communication using LEDs: Enabling Toy Cars Interaction
Communication capabilities are becoming a popular feature for premium smart toys. However, the higher cost of such transmitters are limiting the widespread use to all consumer users. In this contribution, we demonstrate a cost-effective toy communication using LED-based visible light communication (VLC), where messages sent via VLC are i) displayed on a screen, or ii) passed from one node (like a car) to another in a multi-hop way.

Title:   Transportation Activity Analysis Using Smartphones
Transportation activity survey which investigates when, where and how people travel in urban area provides necessary information for urban transportation planning. These surveys are often conducted through conventional paper questionnaires and opinion poll. However, such conventional surveys are error-prone. To address this issue, we are developing a smartphone-based transportation activity survey system. In this paper, we focus on the transport activity analysis algorithms used by the system.
