AS-MAC: Utilizing the adaptive spreading code length for wireless sensor networks
Fei Qin, John E. Mitchell
Article No.: 1
In many modern advanced Wireless Sensor Network (WSN) applications, the system is expected to deliver intensive traffic loads in harsh RF environment. In this article, an MAC protocol has been proposed which will utilize the adaptive spreading...
In wireless sensor networks (WSNs), trap coverage has recently been proposed to trade off between the availability of sensor nodes and sensing performance. It offers an efficient framework to tackle the challenge of limited resources in...
Achieving full-view coverage in camera sensor networks
Yi Wang, Guohong Cao
Article No.: 3
Camera sensors are different from traditional scalar sensors, as cameras at different positions can form very different views of the object. However, traditional coverage model does not consider this intrinsic property of camera sensors. To...
The GINSENG system for wireless monitoring and control: Design and deployment experiences
Tony O'donovan, James Brown, Felix Büsching, Alberto Cardoso, José Cecílio, Jose Do Ó, Pedro Furtado, Paulo Gil, Anja Jugel, Wolf-Bastian Pöttner, Utz Roedig, Jorge Sá Silva, Ricardo Silva, Cormac J. Sreenan, Vasos Vassiliou, Thiemo Voigt, Lars Wolf, Zinon Zinonos
Article No.: 4
Today's industrial facilities, such as oil refineries, chemical plants, and factories, rely on wired sensor systems to monitor and control the production processes. The deployment and maintenance of such cabled systems is expensive and inflexible....
Compression in wireless sensor networks: A survey and comparative evaluation
M. A. Razzaque, Chris Bleakley, Simon Dobson
Article No.: 5
Wireless sensor networks (WSNs) are highly resource constrained in terms of power supply, memory capacity, communication bandwidth, and processor performance. Compression of sampling, sensor data, and communications can significantly improve the...
A connectivity-based and anchor-free three-dimensional localization (CATL) scheme is presented for large-scale sensor networks with concave regions. It distinguishes itself from previous work with a combination of three features: (1) it works for...
We are in an age where people are paying increasing attention to energy conservation around the world. The heating and air-conditioning systems of buildings introduce one of the largest chunks of energy expenses. In this article, we make a key...
Joint k-coverage and data gathering in sparsely deployed sensor networks -- Impact of purposeful mobility and heterogeneity
Habib M. Ammari
Article No.: 8
Coverage is one of the fundamental concepts in the design of wireless sensor networks (WSNs) in the sense that the monitoring quality of a phenomenon depends on the quality of service provided by the sensors in terms of how well a field of...
Gauss-seidel correction algorithm: A macroscopic model-derived routing algorithm for WSNs
Ren-Song Ko, Po-Liang Lin, Pei-Yu Chiang
Article No.: 9
A Gauss-Seidel correction (GSC) routing algorithm for wireless sensor networks is presented in which packets are transmitted with additional information which can be exchanged among nodes to correct the current routing paths and achieve load...
An adaptive sensor sleeping solution based on sleeping multipath routing and duty-cycled MAC protocols
Ou Yang, Wendi Heinzelman
Article No.: 10
Various applications of wireless sensor networks require multihop data transmission over error-prone wireless links, hence multipath routing can be used to meet the application's reliability requirement. On the other hand, wireless sensors are...
Design, development, and performance evaluation of a low-cost, low-power wake-up radio system for wireless sensor networks
Joaquim Oller, Ilker Demirkol, Jordi Casademont, Josep Paradells
Article No.: 11
Energy-efficient operation is a challenge for wireless sensor networks (WSNs). A common method employed for this purpose is duty-cycled operation, which extends battery lifetime yet incurs several types of energy wastes and challenges. A promising...
