On Deploying Wireless Sensors to Achieve Both Coverage and Connectivity
TLDR
This paper proposes an optimal deployment pattern to achieve both full coverage and 2-connectivity, and proves its optimality for all values of rc/rs, where rc is the communication radius, and rs is the sensing radius. Expand
DSSS-Based Flow Marking Technique for Invisible Traceback
TLDR
A new class of flow marking technique for invisible traceback based on direct sequence spread spectrum (DSSS), utilizing a pseudo-noise (PN) code, which requires no training, and can achieve both high detection and low false positive rates. Expand
Mobile phone based drunk driving detection
TLDR
A highly efficient system aimed at early detection and alert of dangerous vehicle maneuvers typically related to drunk driving, which achieves high accuracy and energy efficiency and is implemented on Android G1 phone. Expand
Mobile phone-based pervasive fall detection
TLDR
This paper proposes PerFallD, a pervasive fall detection system tailored for mobile phones, and designs two different detection algorithms based on the mobile phone platforms for scenarios with and without simple accessories. Expand
PerFallD: A pervasive fall detection system using mobile phones
TLDR
This paper designs a detection algorithm based on mobile phone platforms, PerFallD, a pervasive fall detection system implemented on mobile phones and compares its performance with that of existing work and a commercial product. Expand
Mobility Limited Flip-Based Sensor Networks Deployment
TLDR
This paper proposes a minimum-cost maximum-flow-based solution to deployment of sensor networks using mobile sensors that optimizes both the coverage and the number of flips, and observes that increased flip distance achieves better coverage and reduces thenumber of flips required per unit increase in coverage. Expand
Optimal Deployment Patterns for Full Coverage and $k$-Connectivity $(k \leq 6)$ Wireless Sensor Networks
TLDR
It is proved that there exists a hexagon-based universally elemental pattern that can generate all known optimal patterns and the optimality of deployment patterns to achieve 6-connectivity under all ranges of R/sub c/sub/s/s under the proposed deployment-polygon-based methodology. Expand
E-SmallTalker: A Distributed Mobile System for Social Networking in Physical Proximity
TLDR
E-SmallTalker is a distributed mobile communications system that facilitates social networking in physical proximity that automatically discovers and suggests topics such as common interests for more significant conversations and proposes a novel iterative Bloom filter protocol that encodes topics to fit in SDP attributes and achieves a low false positive rate.

D-Scan: Enabling Fast and Smooth Handoffs in AP-Dense 802.11 Wireless Networks
TLDR
This paper studies the handoff process in large AP-dense 802.11 networks, which is one of the most common forms of WiFi under usage, and develops a solution to significantly improve the essential process of AP scan, a bottleneck towards fast and smooth handoffs. Expand
