Research Objectives

Architechtural Optimisation of Large Scale Cloud Based System

Complex IoT-based sensor network architectures could significantly benefit from flexibility, sensing heterogeneity, communication protocol software control, low latency and enhanced operational capacity. Rapidly evolving concepts of network softwarization/virtualization can play a key role in fulfilling the aforementioned requirements. Adoption of network softwarization techniques such as Network Function Virtualization (NFV) for cloud-governed IoT–based sensor networks can offer multiple advantages such as flexible network controllability, increased operational capacity, reduced dependency on hardware and substantial mitigation of Operational Expenditure (OPEX). The goal of this research is to explore how a sensor network can be made vastly flexible to reliably and rapidly meet the dynamic service requirements, as those exuded by the public shared spaces. The study focuses on the implementation of network softwarization techniques such as Network Function Virtualization (NFV) in offering the rapid interaction with the process dynamics.
