IoT-comunity Aware Multicast and Broadcast

In order to secure the Internet of Things, we have proposed to split connected devices into small groups, called as communities of devices. Each of those communities connects devices authorized to communicate with each other using a defined set of applications. To isolate information exchange within each community, the network can be "sliced", with each slice dedicated to a community. However, this network architecture is not well-fit to multicast and broadcast traffics. This document will expose the specific issues regarding the multicast and broadcast traffics within such an IoT environment. It will propose an appropriate solution to work around the described issues. It will also present an enforcement of such a solution within an OpenFlow framework.
