The Internet of Things (IoT) offers the promise of integrating the digital world of the Internet with the physical world in which we live. But realizing this promise necessitates a systematic approach to integrating the sensors, actuators, and information on which they operate into the Internet we know today. This paper reports the design and development of(More)
This paper reports the design and development of an HTML5-empowered Virtual Sensor Editor (VSE) over Internet of Things cloud. VSE is a scalable tool that allows users to design virtual sensors with user-defined dataflow logic, by visually aggregating existing sensors, either physical sensors or user-defined virtual sensors. VSE supports a real-time and(More)
Mobile devices have evolved to become computing platforms more similar to desktops and workstations than the cell phones and handsets of yesteryear. Unfortunately, today's mobile infrastructures are mirrors of the wired past. Devices, apps, and networks impact one another, but a systematic approach for allowing them to cooperate is currently missing. We(More)
—Commercial cellular networks emerged from the wired public switched telephone networks (PSTN) in an evolutionary manner. Market pressures fueled upgrades in bandwidth and functionality. Four decades later, these networks maintain historical artifacts from PSTN networks, and the artifacts work against the fundamental needs of today's wireless systems.(More)
The impact that widespread disasters have on communications systems has evolved over time - fueled by advancements in technology and cemented by societal adoption. As the use of IP-based communications systems, both wired and wireless, has become ubiquitous, we as a society have become dangerously dependent. We vest our banking and healthcare records in(More)
Infrastructure monitoring applications currently lack a cost-effective and reliable solution for supporting the last communication hop for low-power devices. The use of cellular infrastructure requires contracts and complex radios that are often too power hungry and cost prohibitive for sensing applications that require just a few bits of data each day.

The Internet of Things (IoT) aims to integrate the digital world of the Internet with our encompassing physical world. However, existing IoT lacks to provide considerate services, meaning that sensors dynamically "collaborate" to provide context-aware federated sensor data. This paper reports our on-going work developing a sensor service federation and(More)
The crystal and molecular structure of ellagic acid dihydrate has been determined by X-ray diffraction techniques. This acid inhibits the carcinogenic properties of a variety of chemical compounds including benzo[alpha]pyrene-7,8-diol-9,10-epoxide, aflatoxin B1, N-methyl-N-nitrosourea, 3-methyl-cholanthrene and 7,12-dimethylbenz[alpha]anthracene. Ellagic(More)
