In urban environments great effort is directed toward alleviating traffic including the design and implementation of complex software and hardware infrastructure. We introduce the idea of an auction-based mechanism for resolving vehicle intersections using a multi-way group auction mechanism. We propose a supporting infrastructure that has promise for increasing performance and responsiveness to dynamic traffic conditions. In order to evaluate new intersections, we propose new metrics that attempt to capture a more human aspect of vehicular transportation. We demonstrate that Interchange intersections perform well in single and multi-grid configurations, are self-adapting and are responsive to a variety of traffic loads.

In machine learning, concept drift can cause the optimal solution to a given problem to change as time passes, leading to less accurate predictions. Concept drift can be sudden, gradual or reoccuring. Understanding the consequences of concept drift is particularly important in human-centric applications where changes in the underlying data and environment are common and unexpected. In order to gain a better understanding of the adverse effects of different types of concept drift on learners, we propose a novel simulation tool that is able to incrementally generate datasets with customisable concept drift by interacting with a human in a game-like setting. We illustrate our approach by generating and analysing concept drift simulations inspired by body-sensor based long-term activity recognition. Our initial results show that current unsupervised adaptation techniques can be caught in cyclic mislabelling and that a hybrid solution that is self-calibrating and semi-supervised is more robust than any of the two taken separately for this example.

We present an experimental study of the impact of network connectivity on energy usage in low-power wireless. We focus on the ends of the connectivity spectrum and investigate the energy footprint of excessive connectivity as well as poor connectivity. We observe that high connectivity boosts the energy footprint of broadcast traffic, because it is conducive to contention and overhearing. With respect to poor connectivity, we observe that the presence of connectivity outliers may also result in a significant increase of the energy consumption. To enable fair comparisons between experimental runs, we augment our results with quantitative data regarding the network topology during each run.

This paper discusses and evaluates the impact of visualization and interaction strategies for extracting quality information from data in complex networks such as microblogs. Two different approaches to interactive visual representations of data are discussed: an interactive node-link graph and a novel approach where content is separated into interactive lists based on data properties. To assess the two approaches in terms of information credibility, the TopicNets system is compared with “Fluo”, a novel system. An analysis scenario is performed through each system on a set of big data filtered from the Twitter message service. The exposure of content, trade-offs between algorithmic power and interaction complexity, methods for content filtering, and strategies for recommending new content are assessed for each system. Fluo is found to improve on TopicNets ability to efficiently find relevant content primarily by providing a more structured content view, however, TopicNets is more customizable and boasts features which are critical for an expert analyst. The paper concludes with general insights on interface design for information filtering systems to maximize perceived quality of information.

In this paper, we propose a support system for daily living activities based on a user's behavior log in an indoor environment. Generally speaking, daily living activities hardly remain in our memory, so that, determining the order and priority of daily tasks can be difficult. There are studies supporting daily chores based on a behavior log and aiming to improve the work efficiency by using a memory aid. However, most of the existing studies require pre-installation of costly devices such as cameras and sensors, and are limited to supporting a particular task or purpose. There have been proposed many methods based on Augmented Reality (AR) which annotate captured images of the real world with texts, but text-based information may frustrate users. More intuitive user interfaces are required. In this paper, we first propose a user's behavior log management technique which associates each activity log with an object/location in the target indoor space. Then, we propose a method for reproducing AR-based visual effects on the object/location determined based on the log; the method naturally navigates the user to carrying out the intended task. We have implemented a prototype of the proposed method and have conducted subjective surveys to evaluate the effectiveness of the proposed visual effects. We thereby, confirmed that the proposed visual effects can make users more intuitively aware of the intended task than the text-based annotation method.

Opportunistic Networks (OppNets) can be used as an alternative way to communicate or to interact with each other when a fixed communication infrastructure is down during an incident like an earthquake or tsunami. In this paper, we investigate the factors effecting the performance of an OppNets routing protocol which is Binary Spray and Wait protocol in a condition of emergency situation. We have conducted four experiments; 1) 20 pedestrians, 2) 20 cars, 3) 100 pedestrians, and 4) 100 cars. We evaluated this protocol using Opportunistic Networking Environment (ONE) simulator and analyze the performance in term of delivery probability, number of message dropped, latency average, and hop count average by varying size of buffer and message size.

In this paper, we explain in depth the communication protocols between different components of FRIEND: a cyber-physical system for traffic Flow-Related Information aggrEgatioN and Dissemination. Recall that FRIEND (which has been introduced in pervious work, by integrating resources and capabilities at the nexus between the cyber and physical worlds, FRIEND will contribute to aggregating traffic flow data collected by the huge fleet of vehicles on our roads into a comprehensive, near real-time synopsis of traffic flow conditions). The main goal of this paper is to discuss the communication protocols employed by various entities in FRIEND. We discuss one of the most fundamental issues in computer networking, which is how two entities can reliably communicate. We start by introducing notation and by establishing terminology that will be used. Then, we discuss how the Road Side Units (RSUs) communicate with different other entities in FRIEND. Also, how data exchange occurs between RSUs and other entities. Then, we explain the communication between Smart Cat's Eyes (SCEs) and other FRIEND entities.

With the large growth of Online Social Networks (OSNs), several privacy threats have been highlighted, as well as solutions to mitigate them. Most solutions focus on restricting the visibility of users information. However, OSNs also represent a threat for contextual information, such as the OSN structure and how users communicate among each other. Recently proposed deanonymization techniques proved to be effective in re-identifying users in anonymized social network. In this paper, we present Friend in the Middle (FiM): a novel approach to make OSNs more resilient against de-anonymization techniques. Additionally we evaluate and demonstrate throughout experimental results the feasibility and effectiveness of our proposal.

Software reprogramming enables users to extend or correct functionality of a sensor network after deployment, preferably at a low cost. This paper investigates the improvement of energy efficiency and delay of reprogramming, at low resource cost. As enabling technologies data compression and incremental updates are used. Algorithms for both approaches are analyzed, as well as their combination, applied to resource-constrained devices. All algorithms are ported to the Contiki operating system, and profiled for different types of reprogramming. The presented results show that there is a clear trade-off between performance and resource requirements. Furthermore, the best reprogramming approach depends on the type of update. Experimentally, VCDIFF, or the combination of Lempel-Ziv-77/FastLZ for compression with BSDIFF for delta encoding, have been identified as the best possible options.

Energy has always been the number one issue in wireless sensor networks, both because of the resource constraints of sensor nodes and because of the need for untethered operation. In particular, the energy footprint of wireless communication has been the object of a great deal of interest over the past decade. Many applications of sensor networks require nodes to operate for months or even years without supervision, thus making it imperative for nodes to employ low-power radios and to duty-cycle them. To complicate matters further, low-power radios are notoriously exposed to the vagaries of RF propagation. The challenge of achieving energy-efficient and reasonably reliable communication over lossy links has shaped a large body of experimental research, mostly driven by the popular Berkeley motes. In this talk, I will illustrate the highlights of a decade of low-power wireless research, with an emphasis on the key accomplishments in medium access and routing.
