ISOC Fellowship to the IETF

Wow! I got the fellowship to attend the IETF 80 meeting at Prague, Czech Republic. I expect that I have to make a social network with all, espically with whom I can work in future.
I am more interested to know about SIP overload control (SOC) and multipath TCP. I wrote two papers using web technolgy. I should feed my work into this new effort, RTC-Web
My Papers:
1. MOCSP
2. User mobility in a Web-based communication system. That is presented in IMSAA2010 in India.

Globally I have one remark for all participants:

A. Standardization vs Personalization

The keynote speaker of the IMSAA 10, K Ananth Krishnan mentioned that ICT industry does not consider the differences of standardization and personalization. He gave one example of electrical industry - Power sockets. How many electrical different appliances out there for different needs.

Future InterNet Design

I attened one workshop at Forum ATENA in which Vincet Cerf and Bob Khan presented their view on the future of the Internet (cloud Computing), and openness in the Internet architecture.


Last Monday, 28-06-2010 I attended another workshop in which John Day , professor of the Univerisity of Boston, spoke on "Future InterNet Design". There are other three speakers: Guy Pujolle, Kave Salamatian and Michel Riguidel. Since their presentation are in French, I dont have enough capability to understand completely. All the slides can be found in here.


John Day recalled the OSI model that has seven unanswered questions, myths and reality. Returning to the fundamentals is a key important for designing the network architecture.




Many of his efforts (RINA - Recursive Internet Architecture) can be found in here. Besides, there is an initiative to design a new network architecture, called the Pouzin Society. There are plenty of documents which can help to understand the network architecutre and key points for new design. To get more, visit here.

Unconventional Network or Challenged Network

Today, I attended the talk delivered by Dr Roch Glitho at Telecom SudParis. His talk was mainly about the unconventional network (Solar network, wireless sensor network and MANET) that forced to shrink the five layers TCP/IP stack into three layers such as Application, Middleware (Routing and transport) and telecommunication layer (MAC and phy).

He presented two middlewares such as IETF delay/disruption tolerant network (DTN) bundle overlay and the EU 6FP ambient control space (ACS) overlay. Application developer should know about these overlays for developing the services in addition to the business logic. Moreover, interconnections of different overlays will pose big hurdle for user experience.

Kiitos (Thanks in Finnish) to the UBI Summer School Program and UBI Challenge

After a lot of fun and series of group work, we concluded successfully the Summer school on 04-06-2010. Many ideas based on the concept of UBI Display/UBI Hotspot are presented for the evaluation. One clear observation is that each presentation has at least one slide that has Google map of Oulu.

UBI Display is a kind of computer sharing by many people in the city. In this case, users are getting a private space for performing their task (Ex using Web Browser).

UBI Hotspot is a kind of access point (Ex. WiFi Access point), terminology coming from Networking people, for providing the network access to personal devices of the users Ex. Blue Tooth/Wireless Sensor Network).


UBI Challenge
The information about the UBI Challenge contest is my main take away. As a researcher, I feel that R&D assets from the UBI program is huge and can be used to experiment new technological solutions.

One idea would be to propose UBI store where users can create and share new applications and media with others for business benefits.This idea is based on the current trend from the servoce providers and a CELTRIC project called SERVERY.

I would like to particpate this contest. Please feel free to invite me if you have any new ideas to discuss.

All the photos of the UBI summer school program taken by my camera are uploaded into Picasa.

After Sauna and Jacuzzi, 6LoWPAN

We all went to the get-together party evening. It was so excitement when I got first experience of Sauna and Jacuzzi. After the many Finnish beers, I was completely down.

I attened IP based wireless sensor network (WSN) workshop. Tutor is an author of 6LoWPAN book. Zach views the WSN from the networking point of view - connecting the WSN with Internet or fitting into the TCP/IP stack. 6LowPAN reduces IPv6 header from 48 bytes to 2 bytes.

More interesting point for me is that there is a need to go for the new apppliction protocol for the WSN. This new protocol is a kind of optimization of HTTP (reduce overhead) and has new features such as eventing/push support natively. Zach et al propose a new protocol called Constrained Application Protocol - CoAP.

It is in the line of changing the user model of the web that consits of HTTP, URI and HTML. This concept is written in the paper "The smart internet: transforming the web for the user".

2nd Ubiquitous City Seminar 2010: From ? to ?

The seven topics are disucssed in this semainar, most of them are high level view and give highlights on what tutors are going to cover in the next three days.

1. Prof Marcus talked on Urban Informatics and Sustainable cities. During the talk he mentioned that Urban informatics is a young field of study, covering communities and technology - people, place and technology.

He listed some projects (I forget the names) he worked and going to work. Now he proposes to use ubiquitous technology for reducing the carbon foot print and promoting good food culture in terms of GREEN, FIT and FUN.

2. Prof Mikael on Interactive Textures - rethinking materiality.

The computing technology is evoloved from GUI(semiotic turn), ubiquitous computing(immaterial turn), and tangible computing(material turn). He ended up with Texture as a relational lanaguage - composition, connection, competition and compromise.

3. Prof Anind dey on Real World Context-aware systems.
He presents his understanding of UbiComp - computing embedded into everyday objects and environments enhancing everyday activity. Growing pains with context systems are privacy, evalution, error, development/end user support, Intelligent. [Hold Grials with intent, human acitivity].

Context is an abstaction/apporximation for human intention.


4. Dr Zach on IP based wireless sensor network. He presented initially his vision on Internet of things - in terms of size - 10 into 12. Then He mentioned about relevant standardization issues with WSN (see the image below.).

He is leading two deployment work in Oulu - UBI- Advanced Metering Infrastruture for Univerisity of Oulu and deplying 6LoWPAN access points in Oulu city.

5. Dr Jurgen Scheible on Creating and Sharing Artistic Expereinces with Ubiquitous Technology.

He is a media artist and tries to provide tools for digitals painting in urban environments. Basically, mobile device is a basic tool for creating artisitic expereince. Some of the his project are MobiLenin, Mobi Toss, Manhatten story mashpup and Mobi spray.

He goes with his mobile phone, projectors and generators, tries to draw artistic work in public place. Main take away from this talk is .

6. Adam Greenfield on Elements of a networked urbanism.

He wrote a book called EVERYWHERE. His intention is to consider the changes in the design of network urban. The changes are :

A. From Component to resource.

B. From costant to variable.

C. from latent to explicit.

D. From held to share.

E. From expiring to persist.

F. From browse to search.

G. From anonymous to knowable.

H. From deferred to realtime.

I. From passive to interactive.

J. From object to service.

K. From ownership to use.

L. From vehicle to transmobility.

M. From work to coworking.

N. From community to network.

O. From presence to performce.

P. from consume to constituent.

He ended up with a statement of Victor Hugo >.

7. Prof Vassilis Kostakos on Urban Social Network analysis. He is interested on modelling (describe) and prediction. In his talk , he mentioned that

system= computer + human + location. City is a system.

8. Prof Timo Ojala on Open UbiquitousOulu version 2. He is the orgainser of the summer school, and is leading the project to deploy public screen in the Oulu city. Prof Timo is giving the lecture (see the image below)

Two of my friends are keen to know what UBI Display provides (see the image below).

Most of their work on UBI program are published and papers can be found here. It is good opportunity for researcher to explore and enhance (may be later, by deploying new concept/serivces) this real runtime system.

UBI Summer School 2010

I reached Oulu on 29th May, 2010 for attending the summer school for one week, arranged by the UrBan Interactions program.

Mingling with Oulu:

Oulu is a small and peaceful city in Finland. I visited almost important places such as
Oulu Cathedral (Lutheran), science center, market sqares in Oulu. People are generally speaking English. I have started meeting my friends who are coming to same summer school. So far I met three Italians, one Romanian, one Polish and one Canadian.

I try to learn hello and thank you (kiitos) in Finnish.

Technical Discussion:

I met two peope today morning and they were disucssing with me about their topics.
It seems they are focusing on Internet of things in two different perspectives such as self-managing aspect and routing using IP and MAC layer cooperation.

I met two friends (my room mates) from Sweden (Dogan) and Poland (Maciej). One paper from Dogan is very interesting titled Efficient Appplication intergration in IP based sensors network.

Summer school Program:

There are six differnet aspects focusing in this workshop. The topics are real world context-aware systems, urban-informatics and sustainable cities, urban social network analysis, creating and sharing artistic experience with ubiquitous technology, IP based wireless sensor network, and Interactive textures - rethinking materiality. More information about this program can found in here.

I expect that monday plenary session will provide an abstract view on emerging urban computing paradigm. It is not clear what oppotunities and challenges around urban computng exist.

I will attend on IP based wireless sensor network session, lectured by Zach Shelby. He will inspire me by his technical expert and entrepreneurial skill.
