“…Beyond the geo-context related work, there is also related work on (IoT) data distribution approaches and techniques; some of these also consider a subset of the above introduced geo-context dimensions. We see the most closely related approaches in the area of pub/sub, e.g., in IoT [26,27,28,29,30] but also for applications ranging from enterprise to web computing [31,32,33,34,35,36,37,38,39]. In addition, there is also non-pub/sub related work on data distribution in general, e.g., [40,41,42]; neither of these explicitly captures geo-context information.…”

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, mostly focus on data content and not on geo-context, which could help to reduce the dissemination of excess data in many IoT scenarios. In this paper, we propose to use the geo-context information associated with devices to control data distribution. We define what geocontext dimensions exist and compare our definition with concepts from related work.Furthermore, we designed GeoBroker, a data distribution service that uses the location of things, as well as geofences for messages and subscriptions, to control data distribution. This way, we enable new IoT application scenarios while also increasing overall system efficiency for scenarios where geo-contexts matter by delivering only relevant messages. We evaluate our approach based on a proof-of-concept prototype and several experiments.

“…Often, a load balancer is used as a single point of entry for all communications: this creates a single logical broker from the perspective of clients and provides some sort of reliability and vertical scalability [10], [11]. However, such setups are either static and cumbersome to deploy or dynamically implement autoscaling in a central cloud service [12]. Given the limited amount of resources that will be available at the MEC, solutions where additional brokers may be dynamically created or shut down according to the local load conditions become of primary importance, as well as the development of accurate prediction models for resource provisioning [13].…”

The vision of the Internet of Thing is becoming a reality and novel communications technologies such as the upcoming 5G network architecture are designed to support its full deployment. In this scenario, we discuss the benefits that a publish/subscribe protocol such as MQTT or its recently proposed enhancement MQTT+ could bring into the picture. However, deploying pub/sub brokers with advanced caching and aggregation functionalities in a distributed fashion poses challenges in protocol design and management of communication resources. In this paper, we identify the main research challenges and possible solutions to scale up a pub/sub architecture for upcoming IoT applications in 5G networks, and we present our perspective on systems design, optimisation, and working implementations.

“…Basically, there exist two models of Pub/Sub systems: topic-based [3,4,6,5] and content-based [12,22]. In the first model, subscribers share a common knowledge on a set of available topics and every published message is labeled with one of these topics.…”

“…In topic-based Pub/Sub system, a subscriber can register its interests in one or more topics, and then it receives all published messages related to these topics (e.g., Scribe [3], Bayeux [4], DYNATOPS [5], Dynamoth [6], Magnet [7] and DRScribe [8]). The advantages of topic-based Pub/Sub systems when compared to content-based (see Section 5) are mainly that messages can be statically grouped into topics, the diffusion of messages to subscribers is usually based on multicast groups, and the interface offered to the user is simple.…”

VCube-PS: A causal broadcast topic-based publish/subscribe system

In this work we present VCube-PS , a topic-based Publish/Subscribe system built on the top of a virtual hypercube-like topology. Membership information and published messages are broadcast to subscribers (members) of a topic group over dynamically built spanning trees rooted at the publisher. For a given topic, the delivery of published messages respects the causal order. VCube-PS was implemented on the PeerSim simulator, and experiments are reported including a comparison with the traditional Publish/Subscribe approach that employs a single rooted static spanning-tree for message distribution. Results confirm the efficiency of VCube-PS in terms of scalability, latency, number and size of messages.
