Wireless sensor networks are characterized by resource constraints. Therefore, today's sensor networks are implemented from scratch emphasizing code efficiency. This development strategy leads to relatively complex code and bad code reusability in further projects. To improve reusability and development efficiency, it is state-of-the-art in the development of standard information systems to divide applications into at least two parts, the application-logic, providing all the functions to solve a given problem and a reusable distributed middleware providing a container for the application. After developing the middleware once, the developer of further projects need to focus only on the application-logic. Thereby, the development times can be reduced considerably. However, a generic middleware layer replacing code implemented from scratch is not practicable in sensor networks due to resource constraints. Within this paper, we will present a model-driven approach in combination with a template-based code generator to get the best of both development strategies. This approach enables us to generate a tailored middleware for our application including interface-stubs for the application-logic. In contrast to other component-based approaches, the templates can be adopted easily to fulfill specific platform needs. We will demonstrate the practicability of this approach by implementing the control of a model railway.

The sensor Web is a distributed sensing system in which information is shared globally. The emergence of this technology will enable the integration of different sensing platforms with temporal and spatial variability. This has a potential to revolutionise hydrological monitoring and forecasting. Our project will establish a sensor Web test bed in the South Esk river catchment, which is located in the North East of Tasmania. The test bed will allow us to evaluate the emerging open geospatial consortium standards and specifications for sensor Web enablement (SWE) and provide a research platform for developing next-generation hydrological and water resource management tools. We intend to use short-term river flow forecasting as our use case for the SWE test bed.

Multiple target tracking within a monitored field usually focuses on tracking the trajectories of each individual target. However, it is incapable of identifying and locating each target when the amount of targets is large or multiple targets are closely distributed. Based on above consideration, this paper proposes a novel problem of tracking a group target, where a group target is a set of targets whose motions are correlated. A monitoring region covering all group members is proposed to represent the group targetpsilas location. And a report node is selected to collect sensor outputs for determining this monitoring region. Based on binary sensor network which is a generic model of sensor networks, we explore the fundamental limit of the accuracy of group target localization. Furthermore, to reduce network traffic, we propose two algorithms for estimating the center and radius of monitoring region. At last, we analyze the accuracy of these algorithms through both theoretical analyses and simulation results.

Adaptive probability-based broadcast forwarding in energy-saving sensor networks

ACM TRANSACTIONS ON sensor NETWORKS 2008年第2期4卷 6-6页

Networking protocols for multihop wireless sensor networks (WSNs) are required to simultaneously minimize resource usage as well as optimize performance metrics such as latency and reliability. This article explores the energy-latency-reliability tradeoff for broadcast in WSNs by presenting a new protocol called PBBF. Essentially, for a given reliability level, energy and latency are found to be inversely related and our study quantifies this relationship at the reliability boundary. Therefore, PBBF offers an application designer considerable flexibility in the choice of desired operation points. Furthermore, we propose an extension to dynamically adjust the PBBF parameters to minimize the input required from the designer.

Key establishment is a fundamental prerequisite for secure communication in wireless sensor networks (WSN). In this regard, symmetric key cryptography is very attractive in WSN. In this paper, we have proposed Mobile Agent (MA) Based Secure Location aware Key Establishment (MASLKE). In MASLKE, MAs find the location of sensor nodes and this information is used for key generation and distribution. MASLKE provides secure key exchange in intra and inter domain of the network and achieves high connectivity in WSN. Simulation results show that MASLKE is quite effective in achieving the goal of secure key distribution in large scale WSN.

作者： Yanmin Zhu Sye Loong Keoh Morris Sloman Emil Lupu Yu Zhang Naranker Dulay Nathaniel Pryce Department of Computing Imperial College London

Body sensor networks (BSNs) for healthcare put more emphasis on security and adaptation to changes in context and application requirement. Policy-based management enables flexible adaptive behaviour by supporting dynamic loading, enabling and disabling of policies without shutting down nodes. This overcomes many of the limitations of sensor operating systems, such as TinyOS, which do not support dynamic modification of code. Alternative schemes for network adaptation, such as networking programming, suffer from high communication cost and operational interruption. In addition, the policy-driven approach enables fine-grained access control through specifying authorization policies. This paper presents an efficient policy system called finger which enables policy interpretation and enforcement on distributed sensors to support sensor level adaptation and fine-grained access control. It features support for dynamic management of policies, minimization of resources usage, high responsiveness and node autonomy. The policy system is integrated as a TinyOS component, exposing simple, well-defined interfaces which can easily be used by application developers. The system performance in terms of processing latency and resource usage is evaluated.

Efficient data management techniques are needed in wireless sensor networks (WSNs) to counteract issues related to limited resources, e.g. energy, memory, bandwidth, as well as limited connectivity. Self-organizing and cooperative algorithms are thought to be the optimal solution to overcome these limitations. On an abstract level, structured peer-to-peer protocols provide O(1) complexity for storing and retrieving data in the network. However, they rely on underlayer routing techniques. In this paper, we present the virtual cord protocol (VCP), a virtual relative position based efficient routing protocol that also provides means for data management, e.g. insert, get, and delete, as known from typical distributed hash table (DHT) services. The key contributions of this protocol are independence of real location information by relying on relative positions of neighboring nodes, short virtual paths because successors and predecessors are in their vicinity, and high scalability because only information about direct neighbors is needed for routing. Furthermore, VCP inherently prevents dead-ends and it is easy to be implemented.

Multi-sensor Data Fusion via Federated Dual-Band Filter

Multi-Sensor Data Fusion via Federated Dual-Band Filter

引用

ieee international conference on Networking, Sensing and Control

作者： Li-Wei Fong Yu Da College of Business Miaoli Taiwan

A federated dual-band filter is developed for use in multi-sensor systems for target tracking. Filter architecture consists of local processors and global processor to describe the distributed fusion problem due to correlation across track estimates for the same target. Each local processor incorporates modified probabilistic neural network with multiple model filter (MMF) to develop switching capability as adaptive manner to respond the target dynamics. The global processor combines local processor outputs via weighted least square estimator which can be implemented in a parallel structure to facilitate estimation fusion calculation. To determine dual-band process noise levels with MMF, the high level is selected by use of a conservative matrix upper bound to handle the track-to-track correlations and another is chosen as proper low level for tracking when target is not maneuvering. The resulting filter has better tracking performance improvement than traditional information matrix filter. Simulation results are included to demonstrate the effectiveness of proposed algorithm.

In distributed command and control (C 2 ), the primary tool for consistency in operational situational assessment (SA) is the common operational picture(COP) and continuous text updates that define relevant objects, their relationships, and their intent. Context often resides in the warfighterpsilas "conversation," or in manual hand gestures in the battlefield. The primary tactical method for capturing this information resides in text chat and voice communications. There is a primary reliance on text chat (due to its persistence) in hostile tactical environments with little to inform its practice or its improvement. We focus on three areas to improve the ability to communicate SA context by (1) developing a computational approach to acquiring chat SA themes from unstructured text; (2) exploiting the use of icons, images, and symbols in developing an SA language; and (3) prototyping a new technology of inscription with the development of data-generating gloves.

作者： Marco Pugliese Fortunato Santucci Center of Excellence DEWS University of L'' Aquila L'Aquila Italy

This paper proposes a novel hybrid cryptographic scheme for the generation of pair-wise network topology authenticated (TAK) keys in a Wireless sensor Network (WSN) using vector algebra in GF(q). The proposed scheme is deterministic, pair-wise keys are not pre-distributed but generated starting from partial key components, keys management exploits benefits from both symmetric and asymmetric schemes (hybrid cryptography) and each key in a pair node can be generated only if nodes have been authenticated (key authentication). Network topology authentication, and hybrid key cryptography are the building blocks for this proposal: the former means that a cryptographic key can be generated if and only if the current network topology is compliant to the ldquoplanned network topologyrdquo, which acts as the authenticated reference; the latter means that the proposed scheme is a combination of features from symmetric (for the ciphering and authentication model) and asymmetric cryptography (for the key generation model). The proposal fits the security requirement of a cryptographic scheme for WSN in a limited computing resource. A deep quantitative security analysis has been carried out. Moreover the cost analysis of the scheme in terms of computational time and memory usage for each node has been carried on and reported for the case of a 128-bit key.
