Socially Optimal Coexistence of Wireless Body Area Networks Enabled by a Non-Cooperative Game
Jie Dong, David B. Smith, Leif W. Hanlen
Article No.: 26
DOI: 10.1145/2932191

In this article, we enable the coexistence of multiple wireless body area networks (BANs) using a finite repeated non-cooperative game for transmit power control. With no coordination amongst these personal sensor networks, the proposed game...

Secure Positioning in Wireless Sensor Networks through Enlargement Miscontrol Detection
Pericle Perazzo, Lorenzo Taponecco, Antonio A. D'amico, Gianluca Dini
Article No.: 27
DOI: 10.1145/2943782

Wireless sensor networks enable a wealth of new applications in areas such as military, medical, environmental, transportation, smart city, and so on. In many of these scenarios, we need to measure in a secure way the positions of the sensors....

LIPS: A Light Intensity--Based Positioning System for Indoor Environments
Bo Xie, Kongyang Chen, Guang Tan, Mingming Lu, Yunhuai Liu, Jie Wu, Tian He
Article No.: 28
DOI: 10.1145/2953880

This article presents a Light Intensity--based Positioning System (LIPS) for indoor environments. The system uses off-the-shelf light-emitting diode lamps as signal sources and light sensors as signal receivers. The design is inspired by the...

CATS: Cooperative Allocation of Tasks and Scheduling of Sampling Intervals for Maximizing Data Sharing in WSNs
Yawei Zhao, Deke Guo, Jia Xu, Pin Lv, Tao Chen, Jianping Yin
Article No.: 29
DOI: 10.1145/2955102

Data sharing among multiple sampling tasks significantly reduces energy consumption and communication cost in low-power wireless sensor networks (WSNs). Conventional proposals have already scheduled the discrete point sampling tasks to decrease...

BLOW-UP: Toward Distributed and Scalable Space Filling Curve Construction in 3D Volumetric WSNs
Chen Wang, Wei Wei, Hongzhi Lin, Hongbo Jiang, John C. S. Lui
Article No.: 30
DOI: 10.1145/2956551

In wireless sensor networks (WSNs), a space filling curve (SFC) refers to a path passing through all nodes in the network, with each node visited at least once. By enforcing a linear order of the sensor nodes through an SFC, many applications in...

Following Targets for Mobile Tracking in Wireless Sensor Networks
Tian Wang, Zhen Peng, Junbin Liang, Sheng Wen, Md Zakirul Alam Bhuiyan, Yiqiao Cai, Jiannong Cao
Article No.: 31
DOI: 10.1145/2968450

Traditional tracking solutions in wireless sensor networks based on fixed sensors have several critical problems. First, due to the mobility of targets, a lot of sensors have to keep being active to track targets in all potential directions, which...

Two-Hop Relay-Assisted Cooperative Communication in Wireless Body Area Networks: An Empirical Study
Jie Dong, Yu Ge, David B. Smith
Article No.: 32
DOI: 10.1145/2979679

The pervasive use of wireless body area networks (BANs) has incurred potential inter-BAN interference, which can cause severe performance degradation. In this article, the coexistence of BANs is experimentally performed. A relay-assisted...

QoS for Long-Range Wireless Sensors Under Duty-Cycle Regulations with Shared Activity Time Usage
Congduc Pham
Article No.: 33
DOI: 10.1145/2979678

Long-range radio can connect sensors/IoT devices without complex and costly deployment of relay nodes. However, this flexibility comes with stricter legal regulations such as maximum radio activity time per 1-hour period. Under such constraints it...

Reliable and Energy-Efficient Downward Packet Delivery in Asymmetric Transmission Power-Based Networks
Hyung-Sin Kim, Myung-Sup Lee, Young-June Choi, Jeonggil Ko, Saewoong Bahk
Article No.: 34
DOI: 10.1145/2983532

In low-power wireless networks, maintaining multihop connectivity is considered effective in constructing communication routes between individual nodes to a gateway. Since sensor networks are typically used for data collection, multihop routing...

3D-kCov-ComFor: An Energy-Efficient Framework for Composite Forwarding in Three-Dimensional Duty-Cycled k-Covered Wireless Sensor Networks
Habib M. Ammari
Article No.: 35
DOI: 10.1145/2822894

Most existing work on coverage, connectivity, and geographic forwarding considers a two-dimensional (2D) space, where the sensors are deployed in a 2D field. However, there are several cases where the 2D assumption is not valid for the design of...

On a New SDP-SOCP Method for Acoustic Source Localization Problem
Mingjie Gao, Ka-Fai Cedric Yiu, Sven Nordholm, Yinyu Ye
Article No.: 36
DOI: 10.1145/2968449

Acoustic source localization has many important applications. Convex relaxation provides a viable approach of obtaining good estimates very efficiently. There are two popular convex relaxation methods using either semi-definite programming (SDP)...

Yimei Li, Yao Liang
Article No.: 37
DOI: 10.1145/2990196

Energy efficiency is one of the most critical issues in the design and deployment of Wireless Sensor Networks (WSNs). Data compression is an important approach to reducing energy consumption of data gathering in multihop sensor networks. Existing...
