CBAM: A Controller based Broadcast Storm Avoidance Mechanism in SDN based NDN-IoTs

The future Internet paradigm Named Data Networking (NDN) and networking architecture like Software Defined Networking (SDN) and Internet of Things (IoT) has caught the attention of research community. NDN is a future internet standard that builds on the practices of current Internet standard TCP/IP. NDN replaces the nodes address with named data that enhance the availability of data. SDN is a good solution for the emerging technologies, efficient resource utilization and communication. Flexible and high-level programmable nature of the SDN caught the attention of the world towards it. IoT enable everything interconnected with other devices and the internet. In dense IoT scenarios, Broadcast storm problem occurs because of the broadcast nature of NDN. Same type of packets cause this problem, that increase the total number of requests and retransmissions. In-time and fast transmission of highly important packets is an issue in IoT. In this paper, we proposed a Controller based Broadcast Storm Avoidance Mechanism (CBAM)in NDN enabled IoT that reduces the broadcast problem with the help of controller. Our scheme used the efficient flow management of SDN controller to control the broadcast storm and efficient transmissions of packets. We also categorized the packet according to the importance and priority. A naming criteria decides the priority of the packet. CBAM outperforms GIF and traditional NDN Flooding in total number of Interests and content retrieval time.
