Design and development of a cost-effective mobile broadband wireless
access network is a key challenge for many mobile network operators.
Overdimensioning or underdimensioning of the access network results in
additional costs and a reduction of the customer satisfaction,
respectively.
Thushara Weerawardane introduces new transport technologies and features
for High Speed Packet Access (HSPA) and Long-Term Evolution (LTE)
networks. He proposes novel adaptive flow control and enhanced
congestion control algorithms and develops corresponding analytical
models. These models are based on Markov chains and can be performed for
faster analysis evaluation compared to long lasting detailed
simulations. Both simulation and analytical models provide optimum
network performance and reliable guaranteed quality of standard for the
end users during congestion in the transport network. Further, the
author investigates and analyzes the LTE transport network performance
by introducing novel traffic differentiation models and buffer
management techniques during intra-LTE handovers.
