Munjure is a PhD student at the wireless communications research group at ECU. His research project title is "Next Generation wireless Communication Framework: Energy and QoS Considerations"
The concept of ultra-dense small cell networks (SCN) is likely to be a key addition to the fifth generation (5G) wireless communication standard, which is expected to deploy within 2020 to address the challenge of exponential growth of mobile traffic demand. One of the major aims of 5G system is to achieve up to 90% energy saving per service provided, as the ICT sector will account more than 14% of total estimated global energy consumption by 2020. While the concept of small cells in heterogeneous networks addresses the frequency scarcity problem to a great extent, unless otherwise carefully managed, a large number of uncoordinated and lightly loaded small cells significantly increase the power consumption of access network (user to SCNs), contrary to the green communication target of the 5G standard. In addition, the ultra-dense and heavy traffic cells of 5G systems also increase the energy consumption of the backhaul network (SCNs to core network) up to 50% of overall energy consumption. This project aims to develop energy efficient solutions for both the access and backhaul networks in 5G systems while maintaining network quality of service (QoS). The particular focus is to implement an energy efficient resource management and planning system, and green backhauling for 5G systems.
