Abstract

Devices of Internet of Things suffer from severe processing and power constraints, which hinders offering complex network services, other than simple data transmission. In smart city scenarios, the lack of these services, such as security and quality of service, might lead to low performance that can result in disasters in urban centers. In this paper, we propose an agile and effective network function virtualization infrastructure of isolated domains of connected devices, which outsources network tasks from the devices to the networking cloud. The domain isolation is achieved by virtualizing the gateway access node to which IoT devices connect. We have deployed a prototype to provide security and quality of service to IoT applications. Preliminary results show that the gateway virtualization does not impact the performance of virtual network functions. Additionally, our proposal provides security for connected devices, identifying the mallicious traffic with 99.8% accuracy, avoiding denial of essential services, and ensuring quality of service.
