Body Area Networks: A Survey

Abstract Advances in wireless communication technologies, such as wearable and implantable biosensors, along with recent developments in the embedded computing area are enabling the design, development, and implementation of body area networks. This class of networks is paving the way for the deployment of innovative healthcare monitoring applications. In the past few years, much of [...]

Unobtrusive physiological monitoring in an airplane seat

Abstract Air travel has become the preferred mode of long-distance transportation for most of the world’s travelers. People of every age group and health status are traveling by airplane and thus the airplane has become part of our environment, in which people with health-related limitations need assistive support. Since the main interaction point between a passenger [...]

Survey on Contemporary Remote Surveillance Systems for Public Safety

Abstract This paper reviews concisely the historical development and current state of the three different generations of contemporary surveillance systems. Recently, in addition to the employment of the incessantly enlarging variety of sensors, the inclination has been to utilize more intelligence and situation awareness capabilities to assist the human surveillance personnel. The most recent generation [...]

Privacy-Aware Object Representation for Surveillance Systems

Abstract Real-time object tracking, feature assessment and classification based on video are enabling technologies for improving situation awareness of human operators as well as for automated recognition of critical situations. To bridge the gap between video signal-processing output and spatio-temporal analysis of object behavior at the semantic level, a generic and sensor-independent object representation is [...]

Mobile Security: Finally a Serious Problem?

Abstract The growing popularity of wireless technology may have finally attracted enough hackers to make the potential for serious security threats a reality. Comments This paper gives an overview of the growing potential of hacker attacks directed towards mobile media.  The rush to bring new mobile media to market compromises security efforts. Computationally capable ‘smart’ phones allow [...]

ACM Tech Pack on Cloud Computing

Abstract Cloud computing promises to radically change the way computer applications and services are delivered, and managed. Although the term means different things to different people, and includes a bit of marketing hype and technical redefinition, the potential benefits are clear. Large datacenters permit resource sharing across hosted applications and lead to economies of scale [...]

Privacy Preserving Mobility Control Protocols in Wireless Sensor Networks

Abstract With the development of technology, wireless sensor networks (WSNs) performing sensing and communication tasks will be widely deployed in the near future because they greatly extend our ability to monitor and control the physical environment and improve the accuracy of information gathering. Since the sensors are usually deployed in hostile environments and cannot get [...]

SixthSense: A Wearable Gestural Interface

Abstract In this note, we present SixthSense, a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. By using a tiny projector and a camera coupled in a pendant like mobile wearable device, SixthSense sees what the user sees [...]

Fundamentals of Large Sensor Networks: Connectivity, Capacity, Clocks, and Computation

Abstract Sensor networks potentially feature large numbers of nodes. The nodes can monitor and sense their environment over time, communicate with each other over a wireless network, and process information that they exchange with each other. They differ from data networks in that the network as a whole may be designed for a specific application. [...]

Energy Harvesting Sensor Nodes: Survey and Implications

Abstract Sensor networks with battery-powered nodes can seldom simultaneously meet the design goals of lifetime, cost, sensing reliability and sensing and transmission coverage. Energy-harvesting, converting ambient energy to electrical energy, has emerged as an alternative to power sensor nodes. By exploiting recharge opportunities and tuning performance parameters based on current and expected energy levels, energy [...]
