DATA-DRIVEN ALLOCATION OF NETWORK RESOURCES IN UDNs
Silvestre Lomba Malta, supervised by Manuel Fernandez Veiga
Department of Telematics Engineering
Due to UDN characteristics, energy management and energy
consumptions are serious challenges to network operators.
Generally speaking, the UDN is an extension of the
Heterogeneous Network (HetNet), where a large number of small
cells are deployed to offload network traffic from over-crowded
macro cells, such that the overall network capacity can be
improved [1].
Studies have concluded that Base Stations consume about 60%-
80% of energy use in cellular networks [1] [2] [3].
The key patterns of a UDN are the user end (UE) and the UE
mobility [4].
Could users mobility prediction schemes help in the optimization
of power-saving algorithms implemented in coordinated or
uncoordinated cellular network BSC’s/eNB’s
Motivation of the work
Thesis Objectives
• Study prediction schemes of user’s mobility.
• Search new tecniques for sampling, compressing and
summarizing network mobility
information in real-time.
• Evaluate the performance
improvements of knowing mobility
and traffic patterns in UDNs as far as
energy-efficiency is concerned.
• Develop deterministic mean-field approximations for predicting
the performance in large UDNs.
• Literature review.
• Learn and play examples in Network Simulator 3
• Learn how to implement LTE scenarios in NS3
• Get sampled mobility patterns and use them on statisticals learning
tools.
• Make a survey of existing models for energy saving region on BS.
• Make a survey of existing simulation models for spatial configuration
in UDN.
• Apply and combine models for EE with simulation models of UDN
spatial configuration.
