In a battlefield surveillance scenario, data readings and events emerging from a wireless sensor network deployed that may not be used immediately by or simply impossible to transmit to an authorized user (a Soldier) in real time are stored in the network. Without proper protection for the sensitive data generated in this setting, a compromised storage node (by an enemy soldier) may divulge its stored sensitive data about the monitored environment, and even worse, it may alter the data. In this paper, we integrate an elliptic curve cryptography scheme and an erasure coding scheme to provide reliable and secure distributed in-network data storage for sensor networks. the main idea is to distribute each erasure coded fragment appended with a fingerprint to different storage nodes. the fingerprint is to allow each coded data fragment to be independently verified as a valid and correct subset of a specific data item. So, the scheme achieves localization of data error. the proposed scheme is resilient to collusion attack, pollution attack, and data dropping attack, and guarantees forward and backward data secrecy as well. the security of the proposed scheme relies on the intractability of the elliptic curve discrete logarithm problem. Different from the existing solutions, the uniqueness of our method comes from the use of lightweight encryption scheme, which is well suited for resource constrained wireless sensors.

this paper proposes and evaluates a model-driven performance engineering framework for wireless sensor networks (WSNs). the proposed framework, called Moppet, is designed for application developers to rapidly implement WSN applications and estimate their performance. It leverages the notion of feature modeling so that it allows developers to graphically and intuitively specify features (e.g., functionalities and configuration policies) in their applications. It also validates a set of constraints among features and generates application code. Moppet also uses event calculus in order to estimate a WSN application's performance without generating its code nor running it on simulators and real networks. Currently, it can estimate power consumption and lifetime of each sensor node. Experimental results show that, in a small-scale WSN of 16 iMote nodes, Moppet's average performance estimation error is 8%. In a large-scale simulated WSN of 400 nodes, its average estimation error is 2%. Moppet scales well to the network size with respect to estimation accuracy. Moppet generates lightweight nesC code that can be deployed with TinyOS on resource-limited nodes. the current experimental results show that Moppet is well-applicable to implement biologically-inspired routing protocols such as pheromone-based gradient routing protocols and estimate their performance. © 2011 ACM.

Medical sensor networks allow for pervasive health monitoring in hospitals, at home, or on the way. Each user carries a set of wireless medical sensors that allows caregivers to monitor his health state. the privacy and confidentiality of medical data need to be guaranteed at any moment to make sure that third parties cannot access confidential information. Additionally, the system also has to be aware of contextchanges, such as emergencies, to ensure fast access to the medical data, and thus, the safety of the users. In this context, this paper presents a modular context-aware access control model to allow for context-awareness and pro-active decision making during acute, emergency, and normal medical situations. We analyze its structure, features, and operation in detail and further describe how our system can be applied to existing security architectures for medical sensor networks. © 2010 ieee.

We consider a wireless sensor and actor network (WSAN) consisting of a large number of tiny, low-cost sensors uniformly and independently distributed in a two-dimensional geographical region around a few powerful entities, called actors. To save energy, the sensors operate according to sleep/awake schedules in an asynchronons manner. In this setting, we propose a semi-distributed, actor-centric localization algorithm which organizes the sensors in the vicinity of each actor by means of a discrete polar coordinate system. Specifically, each sensor is localized when it acquires the corona and sector coordinates of the region it resides in. To accomplish the localization task, each actor first trains a subset of sensors in its vicinity, which in turn train their neighbors. By modeling the deployed sensors as a two-dimensional Poisson point process and applying well-known results from the Coupon Collector's problem and Chernoff bounds, we derive bounds on the sensor density required to localize with high probability all sensors in the actor's vicinity. Finally, we verify the analytical bounds with results from our simulation experiments. © 2010 ieee.

During the last few years there has been an increasing number of people-centric sensing projects, which combine location information with other sensors available on mobile devices, such as the camera, the microphone or the accelerometer, giving birth to a different dimension in sensing our environment compared to the existing wireless sensor networks approach. In this paper, we envision a new scenario, where users develop their own participatory urban sensing projects at a large scale through the use of social networks. Consequently, users can participate in campaigns created by other users, according to their sensitivities and interests, exploiting the existing enormous social interconnections offered by existing social networking tools. We place our primary concern to protecting user privacy and address the need for new solutions in location anonymity and access control under this new complex and dynamic communication paradigm. © 2010 ieee.

A platform-independent communication mechanism is essential for the seamless integration of embedded devices into the Web of things. Web services provide for such communication, though there remains an open question as to whether they are suitable for hardware-constrained devices. While there is a general perception that they are too resource-intensive, there are few scientific studies dedicated to answering this question. As a result, researchers or developers investigating applications for the Web of things have little evidence to support a decision on the best technical solution. this paper presents the results of a study designed to assess the performance of Web services on embedded devices. For our investigation, we deployed Web services on Sun SPOTs, representing medium-sized wireless sensor platforms, and analysed disk space, message size, response time and energy consumption. Our study quantifies the overhead of Web services and provides empirical data on whether this Web technology is a suitable approach for embedded devices. © 2010 ieee.

Over the past few years, approaches including artificial intelligence models into Wireless sensor Networks have gained much attention within the research community. However, little attention has been paid to integrate Fuzzy Rule Based-systems into Wireless sensor Network. Since traditional approaches of Fuzzy Rule Based-systems cannot be applied, due to limited resources that the sensors nodes have, the principal aim of this work is to design a distributed knowledge based Wireless sensor Network, where each node of the network executes an adapted Fuzzy Rule Based-System. this aim has been divided into the followings: 1) to design a Fuzzy Rule Based-System adapted to a sensor node, 2) to design an application protocol which allows transmitting knowledge bases to sensors nodes and 3) to simulate a particular scenario with network simulator ns-2. the performance of a Sun SPOT sensor has been evaluated and a comparison to other devices is reported. the results show that a Sun SPOT sensor can execute properly a Fuzzy Rule Based-System adapted to it, and that it is possible to create a useful distributed knowledge based Wireless sensor Network.

Maritime surveillance is a difficult task as its aim is to detect any threatening event in a dynamic, complex and hugely distributed system. As there are many different types of vessels, behaviours, situations, and because the system is constantly evolving, classical automated surveillance approaches are unrealistic. We propose an adaptive multi-agent system in which each agent is responsible for a vessel. this agent perceives local anomalies and combines them to maintain a criticality value, used to decide when an alert is appropriate. the importance of the anomalies and how they are combined emerges from a cooperative self-adjusting process taking user feedback into account. this software is currently under development in ScanMaris, a project supported by the French National Research Agency.
