Improved multicriteria spanners for Ad-Hoc networks under energy and distance metrics
Hanan Shpungin, Michael Segal
Article No.: 37
DOI: 10.1145/2489253.2489254

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...

Diagnostic tracing for wireless sensor networks
Vinaitheerthan Sundaram, Patrick Eugster, Xiangyu Zhang, Vamsidhar Addanki
Article No.: 38
DOI: 10.1145/2489253.2489255

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
DOI: 10.1145/2489253.2489256

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
DOI: 10.1145/2489253.2489257

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
DOI: 10.1145/2489253.2489258

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
DOI: 10.1145/2489253.2489259

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
DOI: 10.1145/2489253.2489260

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
DOI: 10.1145/2489253.2489261

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...

Coverage algorithms for visual sensor networks
Vikram P. Munishwar, Nael B. Abu-Ghazaleh
Article No.: 45
DOI: 10.1145/2489253.2489262

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
DOI: 10.1145/2489253.2489263

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...

Cell-based snapshot and continuous data collection in wireless sensor networks
Shouling Ji, Jing (Selena) He, A. Selcuk Uluagac, Raheem Beyah, Yingshu Li
Article No.: 47
DOI: 10.1145/2489253.2489264

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...

DOI: 10.1145/2489253.2489265

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
DOI: 10.1145/2489253.2489267

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...
