Staying Alive: System Design for Self-Sufficient Sensor Networks
Nicola Bui, Michele Rossi
Article No.: 40
Self-sustainability is a crucial step for modern sensor networks. Here, we offer an original and comprehensive framework for autonomous sensor networks powered by renewable energy sources. We decompose our design into two nested optimization...
We study the water quality in an urban district, where the surface wind distribution is an essential input but undergoes high spatial and temporal variations due to the impact of surrounding buildings. In this work, we develop an optimal sensor...
Toward Stable Network Performance in Wireless Sensor Networks: A Multilevel Perspective
Shan Lin, Gang Zhou, Mo’taz Al-Hami, Kamin Whitehouse, Yafeng Wu, John A. Stankovic, Tian He, Xiaobing Wu, Hengchang Liu
Article No.: 42
Many applications in wireless sensor networks require communication performance that is both consistent and of high quality. Unfortunately, performance of current network protocols can vary significantly because of various interferences and...
GreenLocs: An Energy-Efficient Indoor Place Identification Framework
Nam Tuan Nguyen, Rong Zheng, Jie Liu, Zhu Han
Article No.: 43
Understanding indoor mobility patterns of people is important in applications such as targeted advertisement, microclimate control, and delivery of anticipatory notifications. In this article, we devise GreenLocs, a nonparametric, profiling-free,...
The wireless rechargeable sensor network is a promising platform for long-term applications such as inventory management, supply chain monitoring, and so on. For these applications, sensor localization is one of the most fundamental challenges....
Hierarchical Data Aggregation Using Compressive Sensing (HDACS) in WSNs
Xi Xu, Rashid Ansari, Ashfaq Khokhar, Athanasios V. Vasilakos
Article No.: 45
Energy efficiency is one of the key objectives in data gathering in wireless sensor networks (WSNs). Recent research on energy-efficient data gathering in WSNs has explored the use of Compressive Sensing (CS) to parsimoniously represent the data....
Optimized Cooperative Dynamic Coverage in Mixed Sensor Networks
Theofanis P. Lambrou
Article No.: 46
This article considers the problem of improving the dynamic coverage and event detection time of mixed wireless sensor networks (WSNs). We consider mixed WSNs that consist of sparse static sensor deployments and mobile sensors that move...
Integrated Intrusion Detection and Tolerance in Homogeneous Clustered Sensor Networks
Hamid Al-Hamadi, Ing Ray Chen
Article No.: 47
In this article, we propose and analyze dynamic redundancy management of integrated intrusion detection and tolerance for lifetime maximization of homogeneous clustered wireless sensor networks (WSNs). We take a holistic approach of integrating...
Toward Optimal Monitoring of Flow-Based Systems Using Mobile Wireless Sensor Networks
Mahima Agumbe Suresh, Wei Zhang, Weijiao Gong, Radu Stoleru, Amin Rasekh, M. Katherine Banks
Article No.: 48
Monitoring flow-based systems (FBS) (e.g., water distribution systems, oil and gas pipelines, the human cardiovascular system) is of paramount importance considering their economic and health impacts. FBS monitoring typically has been achieved by...
This article considers the data aggregation scheduling problem, where a collision-free schedule is determined in a distributed way to route the aggregated data from all the sensor nodes to the base station within the least time duration. The...
Geospatial Estimation-Based Auto Drift Correction in Wireless Sensor Networks
Dheeraj Kumar, Sutharshan Rajasegarar, Marimuthu Palaniswami
Article No.: 50
Wireless sensor networks are often deployed in large numbers, over a large geographical region, in order to monitor the phenomena of interest. Sensors used in the sensor networks often suffer from random or systematic errors such as drift and...
Position information plays a pivotal role in wireless sensor network (WSN) applications and protocol/algorithm design. In recent years, range-free localization algorithms have drawn much research attention due to their low cost and applicability...
Relay Selection with Channel Probing in Sleep-Wake Cycling Wireless Sensor Networks
K. P. Naveen, Anurag Kumar
Article No.: 52
In geographical forwarding of packets in a large wireless sensor network (WSN) with sleep-wake cycling nodes, we are interested in the local decision problem faced by a node that has “custody” of a packet and has to choose one among a...
