CitySee: Urban CO2 monitoring with sensors
TLDR
This work proposes efficient and effective approaches to sensor deployment, and proves that their scheme uses additional relay nodes at most twice of the minimum, and successfully applies this design into CitySee, a large-scale wireless sensor network consisting of 1096 relay nodes and 100 sensor nodes in Wuxi City, China.
Canopy closure estimates with GreenOrbs: sustainable sensing in the forest
TLDR
GreenOrbs is presented, a wireless sensor network system and its application for canopy closure estimates that outperforms the conventional approaches for canopyclosure estimates by incorporating a pre-deployment training process as well as a distributed calibration method.
Does Wireless Sensor Network Scale? A Measurement Study on GreenOrbs
TLDR
It is suggested that an event-based routing structure can be trained and thus better adapted to the wild environment when building a large-scale sensor network.

Exploiting Constructive Interference for Scalable Flooding in Wireless Networks
TLDR
The root cause of CI is explained with waveform analysis and the closed-form packet reception ratio (PRR) formula is derived and it is analytically shown that CIBF has a PRR lower bound in the grid topology.

TLDR
VOVO, VCR-oriented VOD for large-scale P2P networks is proposed, providing short startup latencies and good performance in VCR interactivities and a collaborative prefetching scheme is proposed to optimize resource distribution among neighboring peers.
Perpendicular Intersection: Locating Wireless Sensors With Mobile Beacon
TLDR
This paper proposes a mobile-assisted localization scheme called Perpendicular Intersection (PI), setting up a delicate tradeoff between range-free and range-based approaches, and shows that PI achieves high accuracy, significantly outperforming the existing range- based and the mobile- assisted localization schemes.
TriggerCast : Enabling Wireless Constructive Collisions
TLDR
This paper redefine CI and proposes TriggerCast, a practical wireless architecture which ensures concurrent transmissions of an identical packet to interfere constructively rather than to interfere non-destructively, and proposes practical techniques to effectively compensate propagation and radio processing delays.
Privacy-preserving high-quality map generation with participatory sensing
TLDR
This work presents a systematic participatory-sensing-based high-quality map generation scheme, PMG, that meets the privacy demand of individual users and is able to generate high- quality maps for a real environment that is robust to noisy data.
ZIGFI: Harnessing Channel State Information for Cross-Technology Communication
TLDR
This paper proposes ZigFi, a novel CTC framework that enables direct communication from ZigBee to WiFi, and builds a generic model through experiments, which describes the relationship between the Signal to Interference and Noise Ratio (SINR) and the symbol error rate (SER).
