Network defense is an elusive art. the arsenal to defend our devices from attack is constantly lagging behind the latest methods used by attackers to break into them and subsequently into our networks. To counteract this trend, we developed a distributed, scalable approach that harnesses the power of collaborative end-host detectors or sensors. Simulation results reveal order of magnitude improvements over stand-alone detectors in the accuracy of detection (fewer false alarms) and in the quality of detection (the ability to capture stealthy anomalies that would otherwise go undetected). Although these results arise out of a proof of concept in the arena of botnet detection in an Enterprise network, they have broader applicability to the area of network self-manageability of pervasive computing devices. To test the efficacy of these ideas further, Intel Corporation partnered with British Telecommunications plc to launch a trial deployment. In this paper, we report on results and insights gleaned from the development of a testbed infrastructure and phased experiments;(1) the design of a re-usable measurementinference architecture into which 3rd party sensor developers can integrate a wide variety of "anomaly detection" algorithms to derive the same correlation-related performance benefits;(2) the development of a series of validation methodologies necessitated by the lack of mature tools and approaches to attest to the security of distributed networkedsystems;(3) the critical role of learning and adaptation algorithms to calibrate a fullydistributed architecture of varied devices in varied contexts, and (4) the utility of large-scale data collections to assess what's normal behavior for Enterprise end-host background traffic as well as malware command-and-control protocols. Finally, we propose Collaborative Defense as a blueprint for emergent collaborative systems and its measurement-everywhere approach as the adaptive underpinnings needed for pervasive services.

We present a sensor network that monitors a hallway. It consists of 180 load sensors connected to 30 wireless sensor nodes, where the setup is of extremely low cost and easily transferred to other settings. Our network serves as a testbed for in-network data processing algorithms, for which it is highly suitable due to the many correlated sensors.

Due to the highly distributed nature and special basic conditions such as limited resources, implementing and maintaining a sensor network application is a tedious task. In this demonstration we present a service-oriented operating system for sensor nodes and a framework that allows a composition of services on the nodes. We show how sensor network applications can be composed and modified by using different services.

Energy efficiency is a common requirement for most WSN applications. We present our approach utilizing precise distributed monitoring of energy consumption to support the development of energy efficient protocols. there-fore we designed dedicated energy monitoring and management hardware for a wireless sensor network testbed. In our demonstration we show distributed energy measurement in a typical sensor network application based on an area monitoring scenario.

the proposed system provides a mechanism of detecting the stealing of valuables, and integrates wireless sensor networks with a location service to trace stolen valuables through deployed cameras in an indoor environment. Compared with traditional surveillance systems, it is able to actively notify the security manager that monitored valuables are stole and show the current positions, and real-time images of those stolen valuables when theft cases occur.

In this work, we study indoor passive tracking problem in wireless sensor networks (WSNs), in which we assume the target being tracked is "clean", i.e., there is no any equipment carried by the target and the tracking procedure is considered to be passive. We design, implement and test our tracking methods in a WSN testbed consisting of 40 wireless sensor nodes and one base station (laptop).

Running efficiency is an important factor to consider in order to avoid injury. In particular, foot pronation, the angle of the foot as it hits the ground, is a common cause for many types of injuries among runners. though pronation is common, diagnosing pronation is difficult and imprecise. Currently there is no method of diagonsis which can quantify the severity of pronation. In this paper we propose using WISP (Wireless Identification and Sensing Platform) sensors to help identify and quantify foot pronation.
