Security schemes of pairwise key establishment, which enable sensors to communicate with each other securely, play a fundamental role in research on security issue in wireless sensor networks. A new kind of pairwise key pre-distribution model for sensor networks is proposed. And in addition, based on which, an efficient dynamic key path establishment algorithm is designed. Theoretic analysis and experimental figures show that the new algorithm has better performance than those previous related works.

While sensor networks have recently emerged as a promising computing model, they are vulnerable to various node compromising attacks. In this paper, we propose COOL, a Compromised nOde Locating protocol for detecting and locating compromised nodes once they misbehave in the sensor network. We exploit a proven collision-resilient incremental hashing algorithm and design secure steps to confidently locate compromised nodes. The scheme can also be combined with existing en-route false report filtering schemes to achieve both early false report dropping and accurate compromised nodes isolation. © Springer Verlag Berlin Heidelberg 2006.

distributed model-free stochastic optimization in wireless sensor networks

2nd ieee international conference on distributed computing in sensor systems

ISBN: (纸本)3540352279

With the improvement in computer electronics in terms of processing, memory and communication capabilities, it has become possible to scatter tiny embedded devices such as sensor nodes to monitor physical phenomena with greater flexibility. A large number of sensor nodes, communicating over the wireless medium, also allows information gathering with greater accuracy than current systems. This paper presents a new stochastic technique known as Incremental Simultaneous Perturbation Approximation (ISPA) for performing optimization in wireless sensor networks. The proposed algorithm is based on a combination of gradient-based decentralized incremental (GBDI) optimization and Simultaneous Perturbation Stochastic Approximation (SPSA) techniques. The former is based on Incremental Sub-Gradient Optimization (ISGO) techniques that allow the algorithm to be performed in a distributed and collaborative manner. The latter component addresses the limitations of the GBDI component especially in real-world sensor networks. Specifically, the SPSA component is a model-free technique that finds the optimal solution without requiring a functional model such as an input-output relationship and a cost gradient. Simulation results show that the proposed ISPA approach not only achieves distributed optimization in a stochastic environment, but can also be implemented in a practical manner for resource-constrained devices. © Springer-Verlag Berlin Heidelberg 2006.

3rd international conference on Broadband Communications Networks and systems

In this paper we address three challenges that are present when building and analyzing wireless sensor networks (WSN) as part of ubiquitous computing environment: the need for an in-situ user interface, a data logger, and a power consumption meter. Solutions for the above have been presented using laptops, personal digital assistants (PDA), onboard flash memory chips of limited size (usually 1MB), and laboratory test equipment. All of them have a good utility for the right applications. However, considering a certain variety of WSNs, where size, battery life, and cost are crucial, none of the above solutions is satisfactory. In this paper we present a compact, lightweight, low power, and low cost multimodal sensor module SeeMote that meets the stated challenges, and is compatible with the popular MICAz mote. Our module has the following components: (1) a graphical user interface component that combines a color liquid crystal display (LCD) and 5-way buttons, (2) a power meter component that is reconfigurable for attaching various low-power devices, and (3) a data logger component that is interfaced to a removable secure digital (SD) or multimedia memory card (MMC). The module dimensions are 34x58x12mm. This paper describes the hardware and software design and experiences while developing and using the device. The device is evaluated by comparing its parameters and functionality to laptop and PDA solutions. We conclude that SeeMote is preferred for certain WSNs, such as very large scale, difficult to reach, and wearable WSNs. We also present several applications that use the LCD module, such as the portable frequency spectrum analyzer and remote sensory data display device.

A camera sensor network is a wireless network of cameras designed for ad-hoe deployment. The camera sensors in such a network need to be properly calibrated by determining their location, orientation, and range. This paper presents Snapshot, an automated calibration protocol that is explicitly designed and optimized for camera sensor networks. Snapshot uses the inherent imaging abilities of the cameras themselves for calibration and can determine the location and orientation of a camera sensor using only four reference points. Our techniques draw upon principles from computer vision, optics, and geometry and are designed to work with low-fidelity, low-power camera sensors that are typical in sensor networks. An experimental evaluation of our prototype implementation shows that Snapshot yields an error of 1-2.5 degrees when determining the camera orientation and 5-10cm when determining the camera location. We show that this is a tolerable error in practice since a Snapshot-calibrated sensor network can track moving objects to within 11cm of their actual locations. Finally, our measurements indicate that Snapshot can calibrate a camera sensor within 20 seconds, enabling it to calibrate a sensor network containing tens of cameras within minutes.

Cooperative public key authentication protocol in wireless sensor network

3rd international conference on Ubiquitous Intelligence and computing

Recent measurements for Public Key Cryptography (PKC) protocols on 8-bit wireless sensor nodes showed optimistic results. It has been shown that Elliptic Curve Cryptography (ECC) is quite applicable to WSN. Still, PKC is much expensive in terms of computation and memory compared by the Symmetric Key Cryptography (SKC). In addition, in PKC, each public key needs to be authenticated before it's used. We believe that sooner or later, PKC will be widely deployed in WSN. Therefore, we present a cooperative distributed public key authentication scheme that does not require any cryptographic overhead. In our scheme, each node is let to store a few number of hashed keys for other nodes. When a public key authentication is required, nodes who store this key help in authenticating it in a distributed and cooperative way. We consider the constrained resources of the sensor node. Additionally, we extend our scheme to fit with small range of authentication error.

To address the problem of unsupervised outlier detection in wireless sensor networks, we develop an algorithm that (1) is flexible with respect to the outlier definition, (2) works in-network with a communication load proportional to the outcome, and (3) reveals its outcome to all sensors. We examine the algorithm's performance using simulation with real sensor data streams. Our results demonstrate that the algorithm is accurate and imposes a reasonable communication load and level of power consumption. © 2006 ieee.

The increasing heterogeneity, dynamism, and uncertainty of emerging DCE (distributed computing Environment) systems imply that an application must be able to detect and adapt to changes in its state, its requirements, and the state of the system to meet its desired QoS constraints. As system and application scales increase, ad hoc heuristic-based approaches to application adaptation and self-management quickly become insufficient. This paper builds on the Accord programming system for rule-based self-management, and extends it with model-based control and optimization strategies. This paper also presents the development of a self-managing data streaming service based on online control using Accord. This service is part of a Grid-based fusion simulation workflow consisting of long-running simulations, executing on remote supercomputing sites and generating several terabytes of data, which must then be streamed over a wide-area network for live analysis and visualization. The self-managing data streaming service minimize data streaming overheads on the simulations, adapt to dynamic network bandwidth, and prevent data loss. An evaluation of the service demonstrating its feasibility is presented. ©2006 ieee.

In this paper we address the issues of forming secure multicast group within wireless sensor networks. We describe a protocol that establishes a secure multicast group, and distributes a group key by mutually authenticating a group of devices over an open insecure wireless channel. We choose a conference keying mechanism and extend it with symmetric authentication protocols and a key hierarchy on which group key could be distributed efficiently. We address two problems in this work. Firstly, the formation of secure groups in sensor network with a low communication complexity, secondly, provides an efficient solution to maintain such multicast group.
