Abstract

The exponential rise of the number of gadgets that are associated with the internet is expanding. At present, there are more than 13 billion gadgets associated with the internet and it is anticipated that this number may reach up to 25 billion by 2020. In an IoT system, these things are embedded to perform explicit tasks in which they are not intelligent enough to understand the significance of the data they were carrying and cannot decide on their own during critical states such as fire accidents. At the point when there is a critical data packet in any of the nodes, other nodes likewise produce the traffic at the same time, which makes the gateway router occupied and makes a delay in message transmission of critical traffic, which might cause potential loss to the productivity. In the proposed design, Software-Defined Networking [SDN] offers a solution for this issue by allowing a wireless sensor network progressively intelligent and furthermore makes network fit for settling on self-decision amid critical state. In the proposed design, an Open vSwitch installed in OpenWRT on a Raspberry Pi as a Data Plane and Open Network Operating System [ONOS] is utilized as a Control Plane. The ESP32 Wi-Fi devices are flashed with the libwebsockets [LWS] factory, which uses HTTP/2 protocol and allows an optional priority tag in the packet header. A routing path with the least latency can be selected during critical state, and traffic engineering can be achieved utilizing SDN.
