Node or Link? Fine-Grained Analysis of Packet-Loss Attacks in Wireless Sensor Networks
Daniele Midi, Elisa Bertino
Article No.: 8
In wireless sensor networks, packet losses are often an indicator of possible undergoing attacks. Therefore, security solutions aiming at providing comprehensive protection must include functions for packet-loss detection. Determining the actual...
Accurate, Dynamic, and Distributed Localization of Phenomena for Mobile Sensor Networks
Christos Anagnostopoulos, Stathes Hadjiefthymiades, Kostas Kolomvatsos
Article No.: 9
We present a robust, dynamic scheme for the automatic self-deployment and relocation of mobile sensor nodes (e.g., unmanned ground vehicles, robots) around areas where phenomena take place. Our scheme aims (i) to sense environmental contextual...
Game Theory Framework for MAC Parameter Optimization in Energy-Delay Constrained Sensor Networks
Messaoud Doudou, Jose M. Barcelo-Ordinas, Djamel Djenouri, Jorge Garcia-Vidal, Abdelmadjid Bouabdallah, Nadjib Badache
Article No.: 10
Optimizing energy consumption and end-to-end (e2e) packet delay in energy-constrained, delay-sensitive wireless sensor networks is a conflicting multiobjective optimization problem. We investigate the problem from a game theory perspective, where...
IdealVolting: Reliable Undervolting on Wireless Sensor Nodes
Ulf Kulau, Felix Büsching, Lars Wolf
Article No.: 11
The energy consumption of Wireless Sensor Networks (WSNs) correlates with the voltage level at which the nodes are powered—a lowered voltage leads to a prolonged lifetime of nodes and networks. Operating nodes at voltage levels below the...
Energy-Efficient Time Synchronization in Wireless Sensor Networks via Temperature-Aware Compensation
Miao Xu, Wenyuan Xu, Tingrui Han, Zhiyun Lin
Article No.: 12
Time synchronization is critical for wireless sensor networks (WSNs) because data fusion and duty cycling schemes all rely on synchronized schedules. Traditional synchronization protocols assume that wireless channels are available around the...
Incentive Mechanisms for Participatory Sensing: Survey and Research Challenges
Francesco Restuccia, Sajal K. Das, Jamie Payton
Article No.: 13
Participatory sensing is a powerful paradigm that takes advantage of smartphones to collect and analyze data beyond the scale of what was previously possible. Given that participatory sensing systems rely completely on the users’ willingness...
Maintaining Large-Scale Rechargeable Sensor Networks Perpetually via Multiple Mobile Charging Vehicles
Weifa Liang, Wenzheng Xu, Xiaojiang Ren, Xiaohua Jia, Xiaola Lin
Article No.: 14
Wireless energy transfer technology based on magnetic resonant coupling has been emerging as a promising technology for wireless sensor networks (WSNs) by providing controllable yet perpetual energy to sensors. In this article, we study the...
Range-Free Mobile Actor Relocation in a Two-Tiered Wireless Sensor and Actor Network
Fang-Jing Wu, Hsiu-Chi Hsu, Chien-Chung Shen, Yu-Chee Tseng
Article No.: 15
Two-tiered wireless sensor and actor networks (WSANs) have been proposed to enhance network capabilities, where a set of resource-rich mobile nodes (termed actors) form a connected backbone to relay sensing data from static sensors to the...
We consider the problem of fusing measurements in a sensor network, where the sensing regions overlap and data are nonnegative real numbers, possibly resulting from a count of indistinguishable discrete entities. Because of overlaps, it is...
