Research Objectives

IoT-Based Sensor Networks: Architectural Optimization of a Large Scale Cloud Based System

Dynamic flexible re-organization of IoT-based sensor networks is essential towards harmonizing its dynamics with that of any monitored external physical phenomenon. Rapidly emerging paradigm of network softwarization, in conjunction with network virtualization, can play a key role in fulfilling the aforementioned requirement. Adoption of network softwarization techniques 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 in offering the rapid interaction with the process dynamics.
