An Empirical Design Space Analysis of Doorway Tracking Systems for Real-World Environments
Erin Griffiths, Avinash Kalyanaraman, Juhi Ranjan, Kamin Whitehouse
Article No.: 26
DOI: 10.1145/3089157

Doorway tracking systems track people’s room location by instrumenting the doorways rather than instrumenting the rooms themselves—resulting in fewer sensors and less monitoring while still providing location information on...

TARS: A Traffic-Adaptive Receiver-Synchronized MAC Protocol for Underwater Sensor Networks
Yu Han, Yunsi Fei
Article No.: 27
DOI: 10.1145/3105149

Efficient medium access control (MAC) is desirable for underwater sensor networks (UWSNs). However, designing an efficient underwater MAC protocol is challenging due to the long propagation delay of the underwater acoustic channel and...

Inferring Clothing Insulation Levels Using Mechanisms of Heat Transfer
Ala Shaabana, Rong Zheng, Zhipeng Xu
Article No.: 28
DOI: 10.1145/3105136

To maintain productivity and alertness, individuals must be thermally comfortable in the space they occupy (whether it is a cubicle, a room, a car, etc.). However, it is often difficult to non-intrusively assess an occupant’s...

Tracking Human Motions in Photographing: A Context-Aware Energy-Saving Scheme for Smart Phones
Yafeng Yin, Lei Xie, Yuanyuan Fan, Sanglu Lu
Article No.: 29
DOI: 10.1145/3085578

Due to the portability of smart phones, more and more people tend to take photos with smart phones. However, energy-saving continues to be a thorny problem, since photographing is a rather power hungry function. To extend the battery life of...

iSelf: Towards Cold-Start Emotion Labeling Using Transfer Learning with Smartphones
Boyuan Sun, Qiang Ma, Shanfeng Zhang, Kebin Liu, Yunhao Liu
Article No.: 30
DOI: 10.1145/3121049

It has been a consensus that a certain relationship exists between personal emotions and usage pattern of the smartphone. Based on users’ emotions and personalities, more and more applications are developed to provide intelligent...

Link Modeling and Delay Analysis in Networks with Disruptive Links
Hassan Peyravi, Rahul Sehgal
Article No.: 31
DOI: 10.1145/3133322

Delay- and Disruption-Tolerant Networks (DTNs) refer to a range of networks with link intermittency that is mainly driven by mobility, predictable or unpredictable network environmental conditions. Examples of DTNs include interplanetary networks,...

A Distance-Based Data Aggregation Technique for Periodic Sensor Networks
Hassan Harb, Abdallah Makhoul, David Laiymani, Ali Jaber
Article No.: 32
DOI: 10.1145/3132682

Monitoring phenomena and environments is an emergent and required field in our today systems and applications. Hence, wireless sensor networks (WSNs) have attracted considerable attention from the research community as an efficient way to explore...
