Multicast Scheduling in SDN WISE to Support Mobile Nodes in Industrial Wireless Sensor Networks

The growing use of mobile nodes in manufacturing environments is increasing the Quality Service (QoS) requirements communications infrastructures that support them, as case with Industrial Wireless Sensor Networks (IWSN). Managing networks using Software Defined (SDN) addresses challenge handling multiple sources a satisfactory manner. global vision topology SDN controller has allows logical segmentation network, through allocation dedicated resources for each information flow, thus ensuring independent service levels and complete isolation. Mobile produce constant changes topology, which lead to instability routing protocols. Traditional solutions protocols such Routing Protocol Low-Power Lossy (RPL) require additional time make parent node change. This paper proposes Multicast Forwarding Network (MMF-SDN), an approach Networking solution WIreless SEnsor (SDN WISE) protocol exploits advantages Time Slotted Channel Hopping (TSCH) synchronism. are managed multicast sources, cumulative from controller. reception states be synchronized at provide network stability, avoiding subsequent recalculations protocol. Parent transparent immediate. proposal improves on other based solutions, reducing energy consumption by up 50%, 70% end-to-end delay improving scalability 30% reduction slotframe occupancy.
