We propose DisCord, an opportunistic protocol for neighbor discovery and data exchange coordination in sensor networks. DisCord allows multiple low-end nodes within radio range to discover each other, self-organize into a network, and exchange data in an autonomous fashion. DisCord can successfully cope with node mobility and unstable network dynamics. Copyright 2010 acm.

Existing sensor network simulators are not appropriate for indoor sensor network systems. We present RealSSim, the sensor network simulator especially developed for indoor sensor networks. RealSSim considers the structure of buildings and the quality of construction materials for accu- rate radio propagation analysis. It also supports an attractive visualization of the level as commercial products. In our demonstration, we show the whole process of simulation for two indoor sensor network systems.

An increasing number of sensor networks have been deployed to monitor a variety of conditions and situations. At the same time, more and more applications are starting to rely on the data from sensor networks to provide users with (near) real-time information and conditions. this increasing demand of users for accurate information about natural and surrounding phoenomena is creating a business case for application providers.

Often software for wireless sensor networks (WSNs) is developed using a specific event based operating system (OS) such as TinyOS. However, this requires steep learning curve for the new developers. Other operating systems for embedded devices have limited support for new hardware platforms. Our goal is to provide an operating system for resource constrained devices that is easy to use for the wide range of researchers and developers familiar with C programming language and Unix operating system concepts. In addition, we provide a framework for agile portability to new hardware platforms, due to the nature of WSN systemsthat require specific hardware or features for the sensing tasks at hand. We propose Multiple agent netted sensor Operating System (MansOS), that demonstrates ability to execute the same application on different platforms including x86 CPU based computers for easy simulation and debugging of a single node or a whole network. the new platforms are easily added to MansOS thanks to the well defined abstraction layers. MansOS is being successfully used in real world applications, such as wild animal tracking and environmental monitoring in a fruit care research garden. It has also been used in academic environment for teaching wireless sensor networks. Copyright 2010 acm.

Powertron is a web-based application that visualizes wireless sensor network deployment data. In this particular demo, we use Powertron to show application-level power data collected from more than 250 sensor nodes. In addition, we expose the routing layer of the deployment by providing real-time interactive visual representation of links, routes, and CTP-related statistics. We hope that the community will have feedback on how such a tool can be extended and generalized to fit a variety of wireless sensor network applications. Copyright 2010 acm.

In this paper, we briefly describe an interactive roulette game enabled over a wireless sensor network platform. It basically consists in a train speeding in one way (the spinning roulette) and in a message hopping along some deployed sensors in the other way (the wheeling ball). this demonstration aims at illustrating in an interactive manner the high radio channel randomness in dense wireless sensor networks, as well as its impact on the communication protocols.

this poster presents an innovative dual-mode medium access control scheme that combines the ultra low power MAC protocol WiseMAC withthe wireless sensor networking standard IEEE 802.15.4. Each network device can independently and autonomously switch between the two modes depending on its residual energy resources and the current application traffic. We observe that this approach can reduce the power consumption and the average latency by almost two orders of magnitude. Copyright 2010 acm.

Wireless sensor Networks (WSNs) have been deployed in a wide range of applications with different sensing and communication requirements. As a consequence, various MAC solutions have been proposed suiting to different application characteristics [1]. However, MAC protocols are typically implemented in a monolithic fashion - specific to a particular hardware platform. this hinders the possibility of code re-use across different platforms, which makes both implementation and porting cumbersome. It also imposes difficulties in protocol redesign when the application requirements change since the entire radio stack needs to be modified.

In recent years, the research of sensor networks has advanced. they are anticipated for use in a wide variety of fields such as traceability systems of products, environmental morning, health care, etc. However, developers must develop applications to work in a sensor node and applications to make the sensor data visible. therefore the knowledge that is necessary for development and the acquisition of the language will take time to develop. As described in this paper, we propose a development environment for sensor network application development. the environgment will be useful even by web programmers and a designers.

the performance of sensor network protocols is greatly affected by the network topology: the network layout, the link dynamics, and the sink placement. We propose the Expected Network Delivery (END), a protocol-independent collection metric that captures the impact of the topology on protocol performance. Our preliminary results with two collection protocols on various topologies on the MoteLab testbed show that the END metric enables a more systematic and topology-aware evaluation of protocol performance.
