Swarm Minimum Broker: an approach to deal with the Internet of Things heterogeneity

The Internet of Things connects billions of objects leveraging the potential of transforming various aspects of society and for improving the quality of lives. The Swarm is an IoT approach in which devices are capable of cooperating with one another in an autonomous and spontaneous manner to fulfill a given mission. Traditional homogeneous middleware cannot handle the vast heterogeneity of devices in the Internet of Things. Previously, we created a heterogeneous and distributed software agent, called Swarm Broker, which offers common services to help devices to interact with each other. In this paper we introduce the concept of a Minimum Broker,the core software that shall be running in resource constrained devices to be part of the Swarm. We also present an implementation of the Minimum Broker and its integration in the Swarm. Additionally, a use case was deployed and the Minimum Broker evaluated.
