TL;DR: The state of the art in research on sensor network security is surveyed, due to the limited capabilities of sensor nodes in terms of computation, communication, memory/storage, and energy supply.
Abstract: Recent advances in electronics and wireless communication technologies have enabled the development of large-scale wireless sensor networks that consist of many low-power, low-cost, and small-size sensor nodes. Sensor networks hold the promise of facilitating large-scale and real-time data processing in complex environments. Security is critical for many sensor network applications, such as military target tracking and security monitoring. To provide security and privacy to small sensor nodes is challenging, due to the limited capabilities of sensor nodes in terms of computation, communication, memory/storage, and energy supply. In this article we survey the state of the art in research on sensor network security.

TL;DR: In this paper, a fuzzy multicriteria analysis (MA) model is used to evaluate service quality of domestic passenger airlines by customer surveys to reflect the inherent subjectiveness and imprecision of the customers' perceptions to the quality levels provided by airlines with respect to multiple service attributes, crisp survey results are represented and processed as fuzzy sets.

TL;DR: A novel routing-driven key management scheme, which only establishes shared keys for neighbor sensors that communicate with each other, which can provide better security with significant reductions on communication overhead, storage space and energy consumption than other key management schemes.
Abstract: Previous research on sensor network security mainly considers homogeneous sensor networks, where all sensor nodes have the same capabilities. Research has shown that homogeneous ad hoc networks have poor performance and scalability. The many-to-one traffic pattern dominates in sensor networks, and hence a sensor may only communicate with a small portion of its neighbors. Key management is a fundamental security operation. Most existing key management schemes try to establish shared keys for all pairs of neighbor sensors, no matter whether these nodes communicate with each other or not, and this causes large overhead. In this paper, we adopt a Heterogeneous Sensor Network (HSN) model for better performance and security. We propose a novel routing-driven key management scheme, which only establishes shared keys for neighbor sensors that communicate with each other. We utilize Elliptic Curve Cryptography in the design of an efficient key management scheme for sensor nodes. The performance evaluation and security analysis show that our key management scheme can provide better security with significant reductions on communication overhead, storage space and energy consumption than other key management schemes.

TL;DR: This investigation of Fenton and Fenton-like reactions at low iron concentration to oxidize three commercial azo dyes reveals that both of these methods can remove the color of these dyes completely and only produce little sludge in wastewater that meet local effluent standards and do not need to further treat.

TL;DR: A Clostridium butyricum strain, isolated from hydrogen-producing sewage sludge, was examined for its ability to produce H 2 from sucrose-based medium under different medium composition, pH, and carbon substrate concentration, suggesting that substrate inhibition may occur.
