PhD Research Title:
This research focuses on optimising 6LoWPAN network parameters to reduce the energy consumption and latency in cluster-based M2M sensor networks, using Software-Defined Networking (SDN) and Network Functioning Virtualisation (NFV) technologies.
Using SDN and NFV in Cloud-based 6LoWPAN Networks as an Energy-Efficient Approach for IoT Environment
Recently, SDN and NFV are being used in M2M sensor networks to add programmability and flexibility features in order to adopt the exponential increment in wireless M2M traffic and enable network configuration even after deployment. The M2M gateway is connected to a cloud computing platform and runs the 6LoWPAN protocol stack. The proposed approach takes the advantage of SDN and NFV paradigms in separating the control plane from the data plane in 6LoWPAN nodes and running the software components on centralised M2M gateway connected to the cloud. The developed approach is called customised Software Defined–Network Functioning Virtualisation (SD–NFV), which is validated through mathematical and experimental analysis using real-time 6LoWPAN testbed. The proof-of-concept testbed relies upon open-source hardware and software platforms to build cost-effective M2M sensor nodes. The obtained results show that the developed SD-NFV gateway reduces the end-to-end delay by approximately 23% and 15% compared to traditional (non SDN-enabled) gateway in terms of data gathering and control message propagation respectively. The obtained results also show that the SD-NFV approach prolongs the sensor node lifetime by 65% in comparison to the traditional 6LoWPAN network.
In summary, the proposed SD–NFV approach is quite suitable for constrained networks where energy and processing efficiency are the major concerns. Furthermore, the SD–NFV gateway improves network programmability, simplicity, and management and its architecture is depicted in Figure 1.
