    In [Avin, C et al., (2004)], the authors proposed the partial cover of a random walk on a broadcast network to be used to gather information and supported their proposal with experimental results. In this paper, we demonstrate analytically that for sufficiently large broadcast radius r, the partial cover of a random walk on a random broadcast network is in fact efficient and generates a good distr...

    Collaborating networks built of hundreds or thousands of tiny, simple nodes, usually operating at low duty cycles, transmitting only few bytes of data are commonly referred to as sensor networks. Since nodes are mostly battery operated, the number one design goal is energy efficiency. It has been understood, that the extreme energy demands can only be met by optimizing all layers and even more imp... View full abstract»

  • Experimental evaluation of lifetime bounds for wireless sensor networks

    In this paper we present a method for experimental lifetime measurements of sensor networks. Despite the importance of experimental validation, none of the lifetime models proposed so far has been validated experimentally. One of the reasons for the absence of practical validations might be the long lifetime of batteries which make the validation of the proposed models non-trivial and time consumi...

    In this paper, we propose a detailed energy survey of the physical, data link, and network layer by analytical techniques. We also show the impact of regular sleep periods on node energy consumption and present a comparison analysis of single-hop vs. multi-hop communications in the energy realm. A detailed energy expenditure analysis of not only the physical layer but also the link and network lay... View full abstract»

    The generic autonomous platform for sensor systems, or GAP4S, is a maintenance-free wireless sensor network in which the sensor battery needs not be replaced. Power is delivered to the sensor via a microwave signal that is radiated by a base-station. The base-station also acts as the entry point to a wider communication network, e.g., the Internet. This paper describes three automatic repeat reque... View full abstract»

  • BitMAC: a deterministic, collision-free, and robust MAC protocol for sensor networks

    Collisions are a source of inefficiency in contention-based MAC protocols that should be reduced to a minimum. We show that concurrent multiple access to a communication channel will, however, not necessarily lead to a collision with undesirable effects. Rather, we demonstrate that it is possible for a receiver to hear the bitwise "or" of the transmissions of multiple synchronized senders within c... View full abstract»

  • /spl mu/-MAC: an energy-efficient medium access control for wireless sensor networks

    For the long-term deployment of wireless sensor networks, energy efficient MAC protocols are necessary. The transceiver of a sensor node should only consume energy while actively taking part in communication. Energy consumption in idle mode should be avoided as much as possible. In this paper it is shown how application layer knowledge in the form of flow specifications can be used to improve the ... View full abstract»

  • PCSMAC: a power controlled sensor-MAC protocol for wireless sensor networks

    In this paper a new power controlled contention-based MAC protocol is introduced for wireless sensor networks where sensor nodes can adjust their transmission power level on a per-frame basis. The main contribution of our work is to enable power controlled transmission of RTS, CTS, DATA and ACK frames while preserving the collision and overhearing avoidance properties of a MAC protocol where these...

    We describe the design and implementation of PEG, a networked system of distributed sensor nodes that detects an uncooperative agent called the evader and assists an autonomous robot called the pursuer in capturing the evader. PEG requires embedded network services such as leader election, routing, network aggregation, and closed loop control. Instead of using general purpose distributed system so... View full abstract»

    This paper describes our experiences using a wireless sensor network to monitor volcanic eruptions with low-frequency acoustic sensors. We developed a wireless sensor array and deployed it in July 2004 at Volcan Tingurahua, an active volcano in central Ecuador. The network collected infrasonic (low-frequency acoustic) signals at 102 Hz, transmitting data over a 9 km wireless link to a remote base ... View full abstract»

    This paper argues for the usefulness of an application-cooperative interactive management system for wireless sensor networks and presents SNMS, a sensor network management system. SNMS is designed to be simple and have minimal impact on memory and network traffic, while remaining open and flexible. The system is evaluated in light of issues derived from real deployment experiences. View full abstract»

    Sensornet systems research is being conducted with various applications and deployment scenarios in mind. In many of these scenarios, the presumption is that the sensornet will be deployed and managed by users who do not have a background in computer science. In this paper we describe the "tiny application sensor kit" (TASK), a system we have designed for use by end-users with minimal sensornet so... View full abstract»

    We present a flexible hardware abstraction architecture (HAA) that balances conflicting requirements of wireless sensor networks (WSNs) applications and the desire for increased portability and streamlined development of applications. Our three-layer design gradually adapts the capabilities of the underlying hardware platforms to the selected platform-independent hardware interface between the ope... View full abstract»

    If the data collected within a sensor network is valuable or should be kept confidential then security measures should protect the access to this data. We first determine security issues in the context of access control in sensor networks especially focusing on the problem of node capture, i.e., the possibility that an attacker can completely take over some of the sensor nodes. We then introduce t... View full abstract»
