Wireless sensor networks are widely used in a variety of commercial and military applications. As a fundamental requirement for providing security functionality in sensor networks, key management plays an essential role in authentication and encryption. In this paper, we propose a Refined Key Link Tree (RKLT) scheme that incorporates dirty key path into the key link tree-based group key management scheme. By delaying key update operations in dirty key paths, the number of duplicate key update messages for auxiliary nodes can be reduced, which also brings down the energy cost. We show through experiments that our RKLT scheme requires fewer rekeying messages than those in the existing group key management schemes.

In mobile ad hoc networks, the nodes are powered by batteries. So one of the most important merits when evaluating a given protocol is its ability to decrease node energy consumption and prolong network lifetime. Concerning this problem, an improved routing algorithm based on extreme prediction is presented for a mobile ad hoc network. It is an energy-saving and stable routing algorithm in which the stable zone is divided by the distance between two nodes and the link availability is calculated according to the area where the node is. The availability of a route is the minimum link availability which consist the whole route and the most stable path is chosen to send information data. And the node adjusts its transmitting power referring to the location of the next hop. Simulation results show that the proposed algorithm decreases network energy consumption effectively compared with basic DSR (Dynamic Source Routing) protocol, and by extension, prolongs the lifetime of the whole network. © 2010 IEEE.

The goal of this paper is to propose a way to processing data from service providing networks using reputation mechanism to user application in agent-based network environment. In this process, it must concern about a lot of sensor network because sensor networks are quite different about data format, protocol, and so on. To alleviate this heterogeneity, we propose data integration mechanism that can convert gathered data from various data gathering network to unified data format. In the agent-based network environment consist of a number of agents and it cooperate each other for establishing their own target but it has problem about lack of reliability. To treat this problem, we propose data integration mechanism for agent-based sensor network middleware to provide enhanced data processing for user application. © 2010 IEEE.

This paper proposes an enhanced pattern discovery algorithm for data streams processing of sensor networks, in order to improve the performance of SPIRIT. The new algorithm adapts the optimized correction for tracking weights vectors, and the dynamic expanding in detecting the number of hidden variables. Simulation results show that compared to the original algorithm, the proposed algorithm can reduce the reconstruction error, increase the energy fraction of reconstruction, and decrease the number of hidden variables, so it extract the principal components and discover patterns among streams more efficiently. © 2010 IEEE.

Data aggregation is an important task in data centric heterogeneous wireless sensor networks because of its varying power and computational capabilities. Due to the deployment of sensor nodes in large numbers for different applications, a single node is not sufficient for performing data aggregation. Hence multiple nodes are required to summarize the relevant information from huge data sets. The process of data aggregation is vulnerable to many threats like loss of cryptographic keys, false data injection etc. To address these issues, we present the Secure Data Aggregation with Key Management (SDAKM) scheme. It provides a secure framework for the data centric heterogeneous wireless sensor networks using additive privacy homomorphism. It uses the heterogeneity of the sensor nodes for performing encrypted data processing and also provides an efficient key management scheme for data communication among sensor nodes in the network. This scheme offers higher security and has less computing overhead as it uses additive privacy homomorphism.

Traditional key management techniques, such as public key cryptography or key distribution center (e.g., Kerberos), are often not effective for wireless sensor networks for the serious limitations in terms of computational power, energy supply, network bandwidth and defection of centra authority. In order to balance the security and efficiency, we propose a new scheme by employing LU Composition techniques for mutualauthenticated pairwise key establishment and integrating LU Matrix with Elliptic Curve Diffie-Hellman for anonymous pathkey establishment. At the meantime, it can achieve efficient group key agreement and management by tree-based extension of LU Matrix Composition key exchange protocol(TGLU). Theoretical analysis shows that the new scheme has better performance and provides authenticity and anonymity for sensor to establish multiple kinds of keys, compared with previous related works.

In industrial applications of wireless sensor networks (WSNs), due to the constraints of limited bandwidth and power, it is not easy to transmit vibration signals in a real-time manner. To address this problem, compressive sensing is exploited to perform vibration signal compression with low computational complexity, which reduces volume of transmitted data and increase transmission efficiency and real-time performance. The fundamentals of compressive sensing enabled signal communication include exploring the inherent sparsity of vibration signals in the frequency domain, compressing the signal with a random Gaussian sampling matrix, and reconstructing the original signal by L-1 norm optimization. A distributed computing paradigm is also proposed to improve the performance of reconstruction by fusing the information of multiple sensor nodes. Experiments show that the proposed distributed compressive sensing enabled signal communication can decrease computational load, improve real-time performance and satisfy the constraints, making it a promising technology for communication in WSNs.

This paper describes wireless wearable and ambient sensors that cooperate to monitor a person's vital signs such as heart rate and blood pressure during daily activities. Each wearable sensor is attached on different parts of the body. The wearable sensors require a high sampling rate and time synchronization to provide a precise analysis of the received signals. The trigger signal for synchronization is provided by the ambient sensors, which detect the user's presence. As wireless technologies, Bluetooth and IEEE 802.15.4 are used for real-time sensing and time synchronization. Thus, this wearable health-monitoring sensor response is closely related to the context in which it is being used. Experimental results indicate that the system simultaneously provides information about the user's location and vital signs, and the synchronized wearable sensors successfully measures vital signs with a 1 ms resolution. ©2010 IEEE.

Using SCXML for semantic sensor networks

Using SCXML for semantic sensor networks

3rd international Workshop on Semantic sensor networks, SSN 2010, Held in Conjunction with the 9th international Semantic Web Conference, ISWC 2010

Future Ubiquitous sensor networks (USNs) are expected to sense and combine multiple descriptions of user contexts, providing a huge potential for the development of revolutionary context-aware applications bridging the physical and digital worlds. Current sensor Web initiatives aim to support ubiquitous access to sensor networks, but to make them really useful for context-aware applications there is still a strong need to develop new mechanisms for enriching sensor data with high-level information, which would constitute a step towards Semantic sensor networks. In this paper, state-charts technology, described according to the W3C SCXML language, combined with the functionalities arising from Semantic Web technologies, are proposed as an efficient, simple and flexible means to make progress towards these objectives. Working with sensor Web data, we propose SCXML-based semantic processing to produce high-level information through automatic embedding of semantic annotations, as well as the identification of relevant contexts. Both of these approaches are useful in a wide range of application domains. The capabilities and limitations of an SCXML processing architecture are also discussed in the context of its implementation over an OSGi framework and its integration into an experimental Telco USN Platform based on OGC® sensor Web Enablement guidelines.
