DICE: Monitoring Global Invariants with Wireless Sensor Networks
Ştefan Gună, Luca Mottola, Gian Pietro Picco
Article No.: 54
DOI: 10.1145/2509434

Wireless sensor networks (WSNs) enable decentralized architectures to monitor the behavior of physical processes and to detect deviations from a specified “safe” behavior, for example, to check the operation of control loops. Such...

Formation Detection with Wireless Sensor Networks
Ioannis Ch. Paschalidis, Wuyang Dai, Dong Guo
Article No.: 55
DOI: 10.1145/2508018

We consider the problem of detecting the formation of a set of wireless sensor nodes based on the pairwise measurements of signal strength corresponding to all transmitter/receiver pairs. We assume that formations take values in a discrete set and...

Maximizing the Lifetime of Query-Based Wireless Sensor Networks
Guvenc Degirmenci, Jeffrey P. Kharoufeh, Oleg A. Prokopyev
Article No.: 56
DOI: 10.1145/2523814

We consider the problem of maximizing the lifetime of a query-based wireless sensor network in which all of the sensor nodes are both producers and consumers of network resources. Of particular concern is the problem of selecting a common...

Spatiotemporal Aquatic Field Reconstruction Using Cyber-Physical Robotic Sensor Systems
Yu Wang, Rui Tan, Guoliang Xing, Xiaobo Tan, Jianxun Wang, Ruogu Zhou
Article No.: 57
DOI: 10.1145/2505767

Monitoring important aquatic processes like harmful algal blooms is of increasing interest to public health, ecosystem sustainability, marine biology, and aquaculture industry. This article presents a novel approach to spatiotemporal aquatic field...

PDVLoc: A Personal Data Vault for Controlled Location Data Sharing
Min Y. Mun, Donnie H. Kim, Katie Shilton, Deborah Estrin, Mark Hansen, Ramesh Govindan
Article No.: 58
DOI: 10.1145/2523820

Location-Based Mobile Service (LBMS) is one of the most popular smartphone services. LBMS enables people to more easily connect with each other and analyze the aspects of their lives. However, sharing location data can leak people's privacy. We...

Maximizing Quality of Coverage under Connectivity Constraints in Solar-Powered Active Wireless Sensor Networks
Benjamin Gaudette, Vinay Hanumaiah, Marwan Krunz, Sarma Vrudhula
Article No.: 59
DOI: 10.1145/2594792

Energy harvesting is a promising solution for reducing network maintenance and the overhead of replacing chemical batteries in sensor networks. In this article, problems related to controlling an active wireless sensor network comprised of nodes...

Sensor Mission Assignment in Rechargeable Wireless Sensor Networks
Thomas La Porta, Chiara Petrioli, Cynthia Phillips, Dora Spenza
Article No.: 60
DOI: 10.1145/2594791

Sensor mission assignment involves matching the sensing resources of a wireless sensor network (WSN) to appropriate tasks (missions), which may come to the network dynamically. Although solutions for WSNs with battery-operated nodes have been...

A Quality-Aware Voice Streaming System for Wireless Sensor Networks
Liqun Li, Guoliang Xing, Limin Sun, Yan Liu
Article No.: 61
DOI: 10.1145/2594775

Recent years have witnessed the pilot deployments of audio or low-rate video wireless sensor networks for a class of mission-critical applications including search-and-rescue, security surveillance, and disaster management. In this article, we...

Flash-Optimized Temporal Indexing for Time-Series Data Storage on Sensor Platforms
Huan Li, Dong Liang, Lihui Xie, Gong Zhang, Krithi Ramamritham
Article No.: 62
DOI: 10.1145/2526687

While it is essential to exploit in-network processing in wireless sensor networks in order to save bandwidth and energy, we are constrained by the limited storage available in off-the-shelf sensor devices. NAND flash memory has great potential...

Low-Cost Indoor Location Management for Robots Using IR Leds and an IR Camera
Baris Tas, Nihat Altiparmak, Ali Şaman Tosun
Article No.: 63
DOI: 10.1145/2536713

Many applications in wireless sensor networks can benefit from position information. However, existing accurate solutions for indoor environments are costly. Radio-Frequency (RF)-based approaches are not suitable for some indoor environments such...

ftTRACK: Fault-Tolerant Target Tracking in Binary Sensor Networks
Christos Laoudias, Michalis P. Michaelides, Christos G. Panayiotou
Article No.: 64
DOI: 10.1145/2538509

The provision of accurate and reliable localization and tracking information for a target moving inside a binary Wireless Sensor Network (WSN) is quite challenging, especially when sensor failures due to hardware and/or software malfunctions or...

Efficient Cluster Mobility Support for TDMA-Based MAC Protocols in Wireless Sensor Networks
Majid Nabi, Marc Geilen, Twan Basten, Milos Blagojevic
Article No.: 65
DOI: 10.1145/2594793

Node mobility is a key feature of using Wireless Sensor Networks (WSNs) in many sensory applications, such as healthcare. The Medium Access Control (MAC) protocol should properly support the mobility in the network. In particular, mobility is...
