Abstract EN

Data exchange is one of the huge challenges in Internet of Things (IoT) with billions of heterogeneous devices already connected and many more to come in the future.

Improving data transfer efficiency, scalability, and survivability in the fragile network environment and constrained resources in IoT systems is always a fundamental issues.

In this paper, we present a novel message routing algorithm that optimizes IoT data transfers in a resource constrained and fragile network environment in publish-subscribe model.

The proposed algorithm can adapt the dynamical network topology of continuously changing IoT devices with the rerouting method.

We also present a rerouting algorithm in Message Queuing Telemetry Transport (MQTT) to take over the topic-based session flows with a controller when a broker crashed down.

Data can still be communicated by another broker with rerouting mechanism.

Higher availability in IoT can be achieved with our proposed model.

Through demonstrated efficiency of our algorithms about message routing and dynamically adapting the continually changing device and network topology, IoT systems can gain scalability and survivability.

We have evaluated our algorithms with open source Eclipse Mosquitto.

With the extensive experiments and simulations performed in Mosquitto, the results show that our algorithms perform optimally.

The proposed algorithms can be widely used in IoT systems with publish-subscribe model.

Furthermore, the algorithms can also be adopted in other protocols such as Constrained Application Protocol (CoAP).
