An Empirical Design Space Analysis of Doorway Tracking Systems for Real-World Environments
Erin Griffiths, Avinash Kalyanaraman, Juhi Ranjan, Kamin Whitehouse
Article No.: 26
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
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
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
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...
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
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
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...
Design Experiences in Minimalistic Flying Sensor Node Platform through SensorFly
Xinlei Chen, Aveek Purohit, Shijia Pan, Carlos Ruiz, Jun Han, Zheng Sun, Frank Mokaya, Patric Tague, Pei Zhang
Article No.: 33
Indoor emergency response situations, such as urban fire, are characterized by dangerous constantly changing operating environments with little access to situational information for first responders. In situ information about the...
Quality of Information in Mobile Crowdsensing: Survey and Research Challenges
Francesco Restuccia, Nirnay Ghosh, Shameek Bhattacharjee, Sajal K. Das, Tommaso Melodia
Article No.: 34
Smartphones have become the most pervasive devices in people’s lives and are clearly transforming the way we live and perceive technology. Today’s smartphones benefit from almost ubiquitous Internet connectivity and come equipped...
