MIDDLEWARE

This article describes my PhD research to date and my plans for future work. The mission of this PhD is to bring flexible and customisable sensing and actuation to a broad new range of devices. My research thus far has focused on μPnP [9], a system that ...

In the Internet of Things (IoT) domain, various heterogeneous ubiquitous devices would be able to connect and communicate with each other seamlessly, irrespective of the domain. Semantic representation of data through detailed standardized annotation ...

Recent years have shown that RDBMS systems do not always meet the performance and scalability requirements of today's applications. Horizontal scalability is hindered by the ACID properties and the normalized data model these systems use. For this ...

The Internet of Things (IoT) vision is being realised recently with many advances in computation and communication technologies and an increasing number of devices with Internet connectivity. Recent efforts have been made to leverage data from these ...

Causal consistency is a consistency criteria of practical relevance in geo-replicated settings because it provides well-defined semantics in a scalable manner. In fact, it has been proved that causal consistency is the strongest consistency model that ...

Efficient resource provisioning is required when running Spark applications in public clouds. However, how to optimize resource provisioning to minimize the time and/or monetary cost for a specific application remains an intractable problem since ...

The publish/subscribe paradigm is well-regarded for its ability to successfully disseminate data while decoupling data providers from data consumers. Traditionally, pub/sub uses two common forms of filtering: topic-based and content-based, with a ...

We introduce Drums, a new tool for monitoring and debugging distributed robot systems, and a complement to robot middleware systems. Drums provides online time-series monitoring of the underlying resources that are partially abstracted away by ...

Embedded devices are widely used in modern life. Smart meters are installed at homes, measure electricity consumption, and provide a two-way communication with the utility server. Modern cars consist of tens of Electronic Control Units (ECU) that ...
