Building IoT Services for Aging in Place Using Standard-based IoT Platforms and Heterogeneous IoT Products

ABSTRACT

An aging population and human longevity is a global trend. Many developed countries are struggling with the yearly increasing healthcare cost that dominantly affects their economy. At the same time, people living with old adults suffering from a progressive Continue reading

Enabling Large-Scale IoT-based Services through Elastic Publish/Subscribe

ABSTRACT

In this paper, we report an algorithm that is designed to leverage the cloud as infrastructure to support Internet of Things (IoT) by elastically scaling in/out so that IoT-based service users never stop receiving sensors data. This algorithm is Continue reading

Exploiting the Capture Effect to Enhance RACH Performance in Cellular-based M2M Communications

ABSTRACT

Cellular-based machine-to-machine (M2M) communication is expected to facilitate services for the Internet of Things (IoT). However, because cellular networks are designed for human users, they have some limitations. Random access Continue reading

Efficient Data Collection by Mobile Sink to Detect Phenomena in Internet of Things

ABSTRACT

With the rapid development of Internet of Things (IoT), more and more static and mobile sensors are being deployed for sensing and tracking environmental phenomena, such as fire, oil spills and air pollution. As these sensors are usually battery-powered, Continue reading

Extensions and Enhancements to “the Secure Remote Update Protocol”

ABSTRACT

This paper builds on previous work introducing the Secure Remote Update Protocol (SRUP), a secure communications protocol for Command and Control applications in the Internet of Things, built on top of MQTT. This paper builds on the original Continue reading

IOTA: Internet of Things Assistant

ABSTRACT

The Internet of Things is the networking of electronic devices, or “Things”, that enables them to collect and share data, as well as interact with their physical surroundings. Analyzing this collected data allows us to make smarter economic decisions. Continue reading
