5G-Enabled Secure IoT Applications in Smart Cities Using Software-Defined Networks

With the idea of shifting towards a smart future there is a lot of research being done in the area of internet of things (IoT) and wireless communication, especially 5G network technology. These technologies are instrumenting society towards a world of high connectivity, through secure evolutionary telecommunication methodologies. In this chapter we understand the role of 5G networks in enhancing IoT devices and discuss their security aspects. Integration of IoT and software defined network termed as SDIoT enables automatic traffic rerouting, device reconfiguration, and bandwidth allocation seamlessly. Smart cities utilize the SDIoT integrated with 5G to gather real-time data, better understand how demand patterns are changing, and respond with quicker and more affordable solutions. The authors try to understand the existing research scenario in 5G networks and IoT, and what areas are being taken into consideration for improvement in the coming future. Copyright
