Robert Bob Lucky is an engineer
known worldwide for his writing and speaking about technology and society.
He invented the adaptive
equalizer, the key enabler for all high speed modems today.
Dr. Lucky has been a frequent
speaker at technical, business, academic, and social occasions.
He received his doctorate in
electrical engineering from Purdue University in 1961.
He has been elected a fellow of
the IEEE and to membership in the National Academy of Engineering
He is a writer of books like Lucky Strikes
Again, IEEE Press, New York, 1992 and
principals of data communication “Lucky, Salz, and Weldon”, McGraw-Hill,
New York, 1965
2. Making list: In 2003 author give Bob’s answer at National
Research Council committee, author gave most of the answers but some of
questions were unanswered and then he thought to make a list of most important
networking questions and possibly there answers, like in 20th
century Hilbert make the list of 23 problems of mathematics and then he told
that we are so busy in solving increasing networking problems that we have no
time to see the range of research problem available there.
2.1 Research related interesting questions: As Hilbert, Heliometer
and Crowcroft the research questions must fulfill the need:
1. The research question must me juicy and good in interest
that it get the attention of research committee.
2. The answers should be in such a greater version that it
broader the view point of the problem and help many other researchers to het in
depth in answers and help them to show greater visibility to solve others
3. It does not
matter if question is interesting or not if getting the answer of the question
does not lead to anything.
4. other most important thing is that after the years of
research the answer of the question has impact on society or not, or someone
just said who cares and then your years of research does not pay off and you
just waste your most of time.
2.2 Checking the question carefully: it describe that the
question meet the worth to have a research on it. Question must be crystal
clear, so that the researcher have idea what the research is going to be all
about and do the question is worth given time.
3. necessary precautions: it describe that the given
question is unsolvable, so you not just waste your time on it or check the
literature that anyone already tried or solves the problem that you are going
to solve again.
4. The question for research: the writer has main focus on
two questions that are peer to peer model connections and wireless security,
because those two problem happens many times that we thought or we want to
4.1 Solving obstacles: Common problem is that we take the
most complex problems to solve so we can get the bright future, but after time
the problem became to be like very difficult to be solved and the same problem
become a barrier between researcher and the future. Instead of that we can take
less complex problem available and try to solve it so it take little resources
and also had a nice impact on society.
1. How to handle parallelism in hubs, switches etc.?
Parallelism: In OS parallelism describes how different
processes or threads can run on different processors or multiple cores of same
processors at the same time. So, computers are getting better and faster day in
and day out but how we can perform parallelism concept on networking devices.
It is a greater concern for network engineers how to make the networking
devices faster to keep up the computing power, what approach would be better
like to make better algorithm for faster networking or increase hardware
performance of networking devices.
2. parallel to serial conversion problem: The old 1990s
problem describe how to connect multicore parallel processing to the serial
processing network. The problem describe that let n is the number of processor greater than 1 and D is the data
divided into parts like d1,….,dn
for parallel processing. So the
problem describes how we can send parallel processed data to a serial processed
network hardware. This problem is one of the main stream problem of networking,
if this problem can be solved we can send data much high seed rate on network
and see the future for networking very bright.
3. Networking processor cores: In multicore processors,
there are many cores interconnected in the same processor act like the
networking of cores in a processor, so many times it happens that multicores
can feel congestion and starvation like it happens in the networking, initially
it feels that it is a simple problem but it is clearly not because ACM HOTNETS
said something different.
4. How to struggle for space: As Clark, Wroclawski and
Sollins describe that struggle for space is one of the most big and important
issues the network face today like in client server model many times server
become bottle neck due to client requests. The internet architecture are lucky
enough to make internet in such a way to save internet for bottle neck but
inter is struggling for space more and more, so it the field of major concern
now a days.
5. What are the profit of faithfully follow the protocol
specification: This question came year’s age and this question is the same as
the struggle for space in question number 4.
6. Making of a cognitive ratio: This is a great concept
comes approximately 20 years ago. The radio hat senses the spectrum available
and make the best use of spectrum by itself. It is the field of AI so still
networking engineers are not able to make a cognitive radio. It is a great
concept where device can automatically check form hundred and thousands of
available configuration choices and make the best choice for transmitting the
radio signals and increase the network performance.
7. Area and platform independent link and language specified
for control radio: The challenge occurs when the radio signals enter into the
new area where the area and signals band are new for it. So we like a specific
language that compile, execute and run different protocols in different
environment. This problem get no attention because network engineer think that
they already have enough and well registered protocols in advance.
8. Accuracy of wireless virtualization: Wireless field has
some serious problems like security, simulations etc. Now a day’s security is a
platform where most of the engineer are working on but, simulations in an area
where engineers need some improvements desperately because available simulation
softwares are not capable for generating results close to reality. Once there
was an emulator RF emulator but after that we are not able to make good
9. How to utilize the full capacity of available bandwidth:
As we know that we have a large spectrum and most of the spectrum is not being
used. So, the question is that how to use the spectrum efficiently. The problem
seems to be very straightforward, but the problem is measurement and
implementation of technology that we can use full spectrum.
