Optimized Routing Scheme in Software Defined Networking for Internet of Things & Comparisons Thereof

Internet of things (IoT) is an advanced technology used in many networking application systems. IoT involves huge number of objects or things that generate enormous amounts of data for storage and processing. The association and control of this enormous volume of information requires original thoughts in the plan and the execution of the IoT system in order to process and improve their presentation. In a similar manner, the Software Defined Networks (SDN) is also a popular networking system and extensively used for monitoring and controlling IoT based devices. Furthermore, OpenFlow is a kind networking protocol mainly used for establishing reliable data transmission in SDNs, which transmits the messages with the help of switches and controllers. In SDN, the controller has the responsibility to coordinate the routing operations of entire network by using switches. Along these lines, to improve the system execution, data packets ought to be routed to the best path. In this paper, the Lion Optimization Algorithm (LOA) is proposed to find the best or optimal path in the data plane of SDN for routing a given packet. By selecting the optimal path between the hosts, the packet loss rate will be reduced and also response time will be improved. Execution of LOA in the SDN environment with OpenFlow Switch system is performed utilizing NS-2 Network Simulator. When compared to the conventional models, the results obtained results using the proposed LOA provide an improved performance values in terms of reduced packet loss rate, increased throughput and packet delivery ratio.
