MQTT is one of the most popular communication protocols for Internet of Things
applications. Based on a publish/subscribe pattern, it relies on a single broker to exchange …

We design Fogstore, a key-value store for event-based systems, that exploits the concept of
relevance to guarantee low-latency access to relevant data with strong consistency …

Abstract In the Internet of Things, the relevance of data often depends on the geographic
context of data producers and consumers. Today's data distribution services, however …

MQTT is one of the promising protocols for exchanging IoT data. IoT data have a
characteristic called" edge-heavy" which means that things at the network edge generate a …

Message queue telemetry transport (MQTT) is a simple and lightweight application protocol
that has attracted attention in Internet of Things (IoT) and M2M communications. Because …

Fog computing is a promising paradigm in terms of extending cloud computing to an edge
network. In a broad sense, fog computing in Internet-of-Vehicles (IoV) provides low-latency …

Message queue telemetry transport (MQTT) is well known as an application layer
communication protocol for the Internet of Things (IoT). Since basic MQTT defines one …

MQTT is one of the promising protocols for various data exchange in IoT environments.
Typically, those environments have a characteristic called “edge-heavy”, which means that …

IoT data are usually exchanged via pub/sub, eg, based on the MQTT protocol. Especially in
the IoT, however, the relevance of data often depends on the geo-context, eg, the location of …

In this paper, we propose a novel dynamic data flow platform for Internet of Things (IoT)
applications in edge computing environments. To avoid the overloads on network and …
