to
-
Machine (M2M) and Green Communications
: This is new project with a focus on
automated communications between different machines using 3GPP wireless technology. Another
facet of the wo
rk is to reduce the energy consumption to make the communication green.




Resource
and Mobility

in

4G Wireless Networks
: This work is focused on profiling user’s
contexts (location and mobility) in upcoming heterogeneous 4G cellular networks and
subsequently development of an early resource reservation scheme. This has the potential to
reduce the handoff latency and improv
e the QoS.




Context
-
awareness in Heterogeneous Smart Environments:

This work investigates the
study of a smart environment equipped with heterogeneous access network technologies (e.g.
smart mall or airports). The complexity of the optimal tracking and res
ource management
problem is identified as NP
-
hard and a near
-
optimal solution is proposed and evaluated.




QoS
-
provisioning in Multimedia Sensor Networks:
Emerging

multimedia sensor networks are
going to be increasingly deployed for applications like video
surveillance and tele
-
medicine. We
have pointed out that QoS routing with multiple QoS constraints (like delay and bandwidth) is an
NP
-
hard problem. Subsequently, we have proposed
QuESt



a new QoS
-
routing protocol for these
multimedia sensor networks, whi
ch provides a set of Pareto
-
Optimal QoS
-
routes.

Differentiated QoS based on service classification of clients to reduce the churn rate and increase

The role of subjective parameters like clients' impatience and its effects (anomalous behavior) in
heterogeneous hybrid scheduling.



Optimal, online hybrid scheduling over multiple channels to minimize overall waiting time.

Doctoral Dissertation:

Title:


A Framework for Dynamic Hybrid Scheduling Strategies in Heterogeneous Asymmetric
Environments
,"

Novelty:

A new framework for hybrid scheduling strategy in heterogeneous, asymmetric, wirel
ess
environments. The framework effectively combines push and pull scheduling to minimize the overall
waiting time perceived by the clients. The entire set of clients is divided into different priority
-
classes
and the scheduling scheme attempts to optimize

the waiting time and blocking of highest priority
clients, thus reducing the churning rate and increasing the profit of wireless service providers. The
dissertation also considers practical, yet subjective measures, like client's impatience and removes th
e
possible anomalies arising in the system. The work is also extended to incorporate the hybrid
scheduling over multiple channels.

Teaching Experience at
Sungkyunkwan

University




Writing IT Technical Pape
rs in English


ECE5902 (Compulsory course for graduate students)
offered widely at SKKU and Samsung Electronics):
This course is designed to teach the students
about writing technical papers in English. The course starts with basics of writing a technical

paper
and covers on the in
-
depth knowledge about drafting every individual section of a technical paper.
At the end of the course the students are expected to write their own research paper in English for
possible submission. The students get knowledgeabl
e enough to start writing basic technical
reports about their research results in English. More specifically, in this course we study all about
research papers and research. We discuss and practice the art of reading, reviewing and writing
good research pa
pers in English. We read many good quality research papers in class and develop
skills of writing a good research paper. We also study on how to make presentations and explore
various topics of Research Methodology.



Operating Systems
-

ECE5658 (Comprehensi
ve course for Doctoral Students)
-

offered at the
Samsung Electronics headquarters specially for the Samsung Employees:
This course is a
graduate level course in operating system. It deals into the different process and memory
management techniques with dea
dlock and all synchronization problems. Students are expected to
solve basic and advanced OS
-
related problems with assignments and exams.



Wireless Networks
-
ECE5303 (Comprehensive course for Doctoral Students)
-

offered at the
Samsung Electronics headquarter
s specially for the Samsung Employees:
This course covers
fundamental techniques in design and operation of: Cellular Systems; Multiple Access Protocols;

Mobility management; Handoff Issues; Location Update and Paging;

Common Air
Protocols (GSM, GPRS, ED
GE, WCDMA, cdma2000); Sensor Network; Adhoc Networks and
the like. This course is intended for graduate students who have some background on computer
networks. Apart from referring the books, the students would be required to read a lot of research
papers

and discuss them in the class. Final exam for the course is a project (with students’ own
research idea) which finally leads to paper writing.



Advanced Data Networks
-
ECE5909 (Comprehensive course for Doctoral students) offered at
the Samsung Electronics h
eadquarters specially for the Samsung Employees:

This course covers
the advanced topics on wireless networks. Majorly focusing on: Ubiquitous and Pervasive
Computing; WiMAX systems; 4G Heterogeneous Networks with pico or femto cells environments


issues
and potentials. This course is intended for graduate students who have background in
computer networks. Apart from referring the books, the students would be heavily engaged in
reading lots of research papers. The students would be required to read these r
esearch papers and
discuss them in the class with student’s possible novel ideas.



Advanced Data Communications:

The course is designed to provide the graduate students
sufficient knowledge about pervasive and ubiquitous environments. It starts with the his
tory and
motivation behind the development of pervasive and ubiquitous environments and covers most of
the major related projects (ongoing / completed) across the world. Students are taught to deal with
advanced technologies and read some research articles
. At the end of the course, they are expected
to come up with some good project and / or seminar presentation involving this state
-
of
-
the
-
art
computing paradigm.



Genetic Algorithms:
The course is designed to provide the graduate students in
-
depth knowledge

about Genetic Algorithms (Evolutionary Computation)


a popular, guided, randomized search
technique, generally used to solve NP
-
complete problems in polynomial
-
time. The course starts
with the basics of genetic programming and will cover most of the majo
r genetic operations.
Students will be taught to solve many real
-
world problems using this efficient tool. The theoretical
insights underlying in the genetic operations and its advancements will also be discussed. At the
end of the course, they are expecte
d to come up with good project and presentation solving real
-
world NP
-
complete problems using this tool.
