Managing Large Iot Network Using SDN And Hierarchical Tree Topology

Abstract

The study covers the potential of managing large Internet of Things (IoT) networks, such as Smart City network using the Software-Defined Networking (SDN) approach. A hierarchical tree topology provides an efficient and scalable solution for connecting a vast number of IoT devices in a Wide Area Network (WAN). The tree topology makes it simple to manage and add or remove IoT nodes from the network due to its hierarchical structure. Additionally, the topology can be highly fault-tolerant, as each IoT node has redundant paths to the root node. By implementing a 1024-node IoT network with a hierarchical tree topology and leveraging the Ryu controller for centralized management, we aim to investigate the performance characteristics of such a network. Performance evaluation conducted for network size of 4,8,16,144 and 1024 hosts for TCP and UDP traffic using Mininet that is network emulation tool, Iperf used for bandwidth and Throughput analysis, and Ping for latency and packet loss measurements. The findings will offer valuable insights for optimizing large-scale IoT deployments.
