Software defined network as solution to overcome security challenges in IoT

IOT has proven to be the most emerging technology where millions of devices can connect to the internet which makes the life feasible without any human intervention. This paper has analysed the challenges associated with IOT technology. Two major issues security and privacy of data and user information has discussed in detail. In this research paper solution of major issue of security is also proposed. One of the important requirements of IOT is to have a quality of service where the data among the devices should be as high as possible without degrading the performance. In this paper, we have proposed a software model based on Software Defined Network (DTN). Software Defined Network is a technology that increases the performance of the network and reduces the hardware usage and also provides a better security and privacy compare to the traditional networks. Lastly, the paper has discussed about the architectural design of SDN and suitable for IoT and Ad-hoc networks.
