Improved multicriteria spanners for Ad-Hoc networks under energy and distance metrics
Hanan Shpungin, Michael Segal
Article No.: 37
We study the problem of spanner construction in wireless ad-hoc networks through power assignments under two spanner models—distance and energy. In particular, we are interested in asymmetric power assignments so that the induced...
Wireless sensor networks are typically deployed in harsh environments, thus post-deployment failures are not infrequent. An execution trace containing events in their order of execution could play a crucial role in postmortem diagnosis of these...
Performance evaluation of sensor networks by statistical modeling and euclidean model checking
Youngmin Kwon, Gul Agha
Article No.: 39
Modeling and evaluating the performance of large-scale wireless sensor networks (WSNs) is a challenging problem. The traditional method for representing the global state of a system as a cross product of the states of individual nodes in the...
Adaptive k-coverage contour evaluation and deployment in wireless sensor networks
Jang-Ping Sheu, Guey-Yun Chang, Shan-Hung Wu, Yen-Ting Chen
Article No.: 40
The problem of coverage is a fundamental issue in wireless sensor networks. In this article, we consider two subproblems: k-coverage contour evaluation and k-coverage rate deployment. The former aims to evaluate, up to k, the...
A high-frequency sampling monitoring system for environmental and structural applications
Cesare Alippi, Romolo Camplani, Cristian Galperti, Antonio Marullo, Manuel Roveri
Article No.: 41
High-frequency sampling is not only a prerogative of high-energy physics or machinery diagnostic monitoring: critical environmental and structural health monitoring applications also have such a challenging constraint. Moreover, such unique design...
DutyCon: A dynamic duty-cycle control approach to end-to-end delay guarantees in wireless sensor networks
Xiaodong Wang, Xiaorui Wang, Liu Liu, Guoliang Xing
Article No.: 42
It is well known that periodically putting nodes into sleep can effectively save energy in wireless sensor networks at the cost of increased communication delays. However, most existing work mainly focuses on the static sleep scheduling, which...
Energy efficiency in wireless sensor networks: A game-theoretic approach based on coalition formation
Artemis C. Voulkidis, Markos P. Anastasopoulos, Panayotis G. Cottis
Article No.: 43
A coalitional game theoretic scheme is proposed that aims at maximizing wireless sensor network lifetime under specified QoS. Employing a small number of nodes of increased computing power and lifetime called representatives, an adaptive...
A game theory distributed approach for energy optimization in WSNs
Andrea Abrardo, Lapo Balucanti, Alessandro Mecocci
Article No.: 44
One of the major sources of energy waste in wireless sensor networks (WSNs) is idle listening, that is, the cost of actively listening for potential packets. This article focuses on reducing idle-listening time via a dynamic duty-cycling technique...
Visual sensor networks (VSNs) are becoming increasingly popular in a number of application domains. A distinguishing characteristic of VSNs is to self-configure to minimize the need for operator control and to improve scalability. One of the areas...
Distributed lifetime-maximized target coverage game
Li-Hsing Yen, Che-Ming Lin, Victor C. M. Leung
Article No.: 46
Wireless sensor nodes are usually densely deployed to completely cover (monitor) a set of targets. Consequently, redundant sensor nodes that are not currently needed in the covering task can be powered off to conserve energy. These sensors can...
Data collection is a common operation of wireless sensor networks (WSNs). The performance of data collection can be measured by its achievable network capacity. However, most existing works focus on the network capacity of unicast, multicast...
On the quality and value of information in sensor networks
Chatschik Bisdikian, Lance M. Kaplan, Mani B. Srivastava
Article No.: 48
The increasing use of sensor-derived information from planned, ad-hoc, and/or opportunistically deployed sensor networks provides enhanced visibility to everyday activities and processes, enabling fast-paced data-to-decision in personal, social,...
Trade-off between energy efficiency and report validity for mobile sensor networks
Huai-Lei Fu, Phone Lin, Yuguang Fang, Ting-Yu Wang
Article No.: 49
Mobile sensor networks (MSNs) have been widely deployed to provide a ubiquitous solution to real-time monitoring applications such as traffic data collection in vehicular ad-hoc networks (VANETs), ocean data collection in underwater sensor...
Sensor node source privacy and packet recovery under eavesdropping and node compromise attacks
Kanthakumar Pongaliur, Li Xiao
Article No.: 50
Securing a sensor network poses a variety of problems. Of those, an important one is of providing privacy to the event-detecting sensor node and integrity to the data gathered by the node. Compromised source privacy can inadvertently leak event...
Results on finite wireless sensor networks: Connectivity and coverage
Ali Eslami, Mohammad Nekoui, Hossein Pishro-Nik, Faramarz Fekri
Article No.: 51
Many analytic results for the connectivity, coverage, and capacity of wireless networks have been reported for the case where the number of nodes, n, tends to infinity (large-scale networks). The majority of these results have not been...
Capacity- and energy-aware activation of sensor nodes for area phenomenon reproduction using wireless network transport
Xiaolong Huang, Izhak Rubin
Article No.: 52
We consider a sensor network involving sensors placed in specific locations. An area phenomenon is detected and tracked by activated sensors. The area phenomenon is modeled to consist of K spatially distributed point phenomena. The...
Thermal-aware sensor scheduling for distributed estimation
Domenic Forte, Ankur Srivastava
Article No.: 53
A sensor network is a distributed system where sensor nodes autonomously collect local data and collaborate to solve global problems. Recent work has shown that sensor functionality varies with node temperature. Extreme temperatures can decrease...
Managing software evolution in large-scale wireless sensor and actuator networks
Barry Porter, Geoff Coulson, Utz Roedig
Article No.: 54
Wireless sensor and actuator networks (WSANs) will increasingly require support for managed software evolution: that is, systematic, ongoing, efficient and nondisruptive means of updating the software running on the nodes of a WSAN. While aspects...
