In modern society, a large portion of the population suffers from sleep disorder. Some sleep disorders are serious enough to interfere with functioning of daily lives. therefore knowing how well one sleeps is an important health indicator that can lead to more aggressive actions. In this demo, we present SNORES: sensor Networks Oriented REsearch in Sleep. SNORES is an in-home sleep monitoring system that is inexpensive, easy-to-install, and less intrusive.

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).

the rapid development of wireless sensor networks (WSNs) and the increasing complexity of the deployed applications force researchers to turn to testbeds to test their communication and application related algorithms and protocols. On the other side, industries' demand for young professionals with WSN expertise is growing too. these two factors motivated us to develop a highly modular and extensible testbed, called Atelier, as part of our bachelor level course on WSNs. In this paper we share our testbed design and describe its main requirements and challenges.

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.

the current rapid development and deployment of wireless sensor networks (WSNs) and their application in mission critical systems are exacerbating the need for high confidence WSNs. Achieving high confidence WSNs will require new assurance technologies. Most current solutions deal with faults and reliability and not with application level semantics and associated assurances. We propose the use of a novel WSN design and assurance mechanism, run time assurance (RTA), to guarantee that important application-level requirements are met in mission critical applications.

the ease of deploying wireless camera sensor nodes has grown withthe reduction of manufacturing costs of low power, high resolution cameras. Although current wireless sensor network platforms have limited on-board resources for solving highly complex computer vision problems, we show that by splitting the processing costs between the sensor node and a powerful backend, we can achieve better classification results. Using such a distributed processing approach, we balance the computational and communication costs for achieving better detection performance while improving the system lifetime.

the energy-efficient management of wireless sensor networks is a demanding task: It has to trade off the need for a detailed insight into the network internals against the energy consumption of the management system itself. We demonstrate a management framework that significantly reduces the communication overhead spent on sending and receiving messages for management purposes while being completely independent from the running sensing application. the management software running on the sensor nodes is able to aggregate management data and data from the actual sensing application. the energy saved on management measures can considerably prolong the lifetime of a wireless sensor network and hence increase the value of an installed sensor network.

HONS (Hybrid Open Networking Stack) is a system which can service diverse types of sensor nodes as a single network. By defining open packet format of IEEE 802.15.4 standard, it can form low-power multi-hop network of diverse sensors. HONS system is composed of routers and wireless sensor nodes. Routers are motes with wired power and form the basic backbone of the multi-hop network. Wireless sensor nodes are motes powered by battery, and operate in a lower-power mode, and are attached to the multi-hop network formed by routers.

the sensorFly system is a novel, low-cost, miniature controlled-mobile aerial sensor network. Mobility permits the network to be autonomous in deployment, maintenance and adapting to the environment, overcoming the reliance of traditionally fixed networks on human intervention, large infrastructure or inefficient random methods. We wish to demonstrate the novel hardware design, flight control and collaborative localization capabilities of the sensorFly system. To the best of our knowledge, this is the lightest realized flying sensor system in existence, with a weight of 30g and low mass production cost of similar to$100. Developed under severe weight, cost, energy and processing power constraints, we show that this system is a viable and capable mobile sensor network platform.

Macroprogramming abstractions provide abstract distributed data structures to simplify the programming of wireless embedded networks. However, none of the current macroprogramming systems provide debugging support for application development. We have developed MDB, a GDB-like post-mortem debugger for the MacroLab macroprogramming abstraction. In this demonstration, we show how MDB enables application development and debugging at a single level of abstraction. MDB eliminates the need for a programmer to reason about low-level event traces and message passing protocols, instead allowing debugging in terms of abstract data types. We expect MDB to fill a crucial link in the development cycle as a macroprogram progresses from the drawing board to real deployment.
