Research work on mobility in IPv6
/ Press-room / Projects / Mobility in IPv6

Description


Theme of research work: "Application of technology MIPv6 for creation of mobile network systems. Aspects of construction, updating and management."

The research adviser - Alekseev Igor Vadimovich
The researcher - Egorov Sergey
Operating time above the project: 01.2006-06.2006.

Object of the given research are the mobile networks which are technology MIPv6 based.
The purpose of the project - construction of practically significant safe mobile network (various variants), consideration of actions on management and updatings of the constructed network.
The theme of mobility is actual for today. Progress in studying the given theme will promote fastest transition on IPv6. And after final introduction of the new report, the given research work will find wide practical application - in fact it almost the unique source which has reflected the regular decision of a problem, and it's written in Russian.
Doubtless value of work is full reliability of the information. It managed to achieve by means of experimental check.
During research the mobile networks corresponding three schemes have been constructed. In the scheme 1 all units work under control of OS FreeBSD.

Scheme 1 
Scheme 1


As there is no more convenient operational system, than Windows in the world, from the point of view of the user, the decision to use computers under control of this OS as final units of a mobile network was accepted. At check of working capacity of the network corresponding the scheme 2, was the malfunction connected with lacks of OS Windows XP is found out.

Scheme 2 
Scheme 2


The scheme 3 is optimum for the decision of a task of construction practically significant (have the greatest practical value) a mobile network (final units work under control of Windows).

Scheme 3 
Shceme 3


Configuring of Windows units includes the task of addresses and routes, and also inclusion of support of functionality of the correspondent node.
Configuring of FreeBSD units is based on use of stack KAME which part is stack SHISA. OS and stacks are in an easy approach, are absolutely free-of-charge and ideally approach for achievement of an object in view of research.
First, on all units is setting up last version KAME with a number of mobile options and devices. Further, various demons (special programs) responsible for maintenance of mobility are setting up and configuring. Among them demons HA, CN, MN, MR, a demon of detection of moving, and also demons of the announcement and inquiry of routers. Safety is adjusted only on house agents and mobile objects (as mobile object it is understood MR or MN). Last stage is configuring of a boot file. It includes the task of routes, purpose of addresses and mobile configuration.
Now construction of a mobile network is completed.
Further, check of working capacity. Includes viewing various tables and caches, check and trace of approachability of unit, interception of packages, viewing of IP-addresses on mobile object, and also executing of script, written by the researcher for definition of a current site of mobile object in a network, on the removed node (CN).
And the last, that is done in research, is the building the list of the actions necessary at updating of the constructed network by means of addition or removal of units. It consists of two stages - 1). Configuring of the unit and 2). Configuring other units of a network. Actions are the same as earlier (a kernel, demons, safety, rc.conf).

So, the given objection is succeeded.
Besides, according to the technique developed in research, evident laboratory stands which are bright acknowledgement of reliability and scale of the written documentation have been created. The created stands with success are introduced in the Center the Internet of Yaroslavl state university of name P.G. Demidov.
Mobile networks can be applied in various fields of activity with the purpose of increase not only economic (increase of a standard of living), but also social security and stability of a society (for example: formation, medicine, sports, sphere of services). Process of transition of the results, received at research, becomes simpler owing to excellent scalability, and also freedom-of-charge of OS FreeBSD and stack KAME, and becomes complicated because of process of transition on IPv6 was too tightened. However after universal transition to the new report undoubtedly there will come an epoch of mobility.

The response of research adviser and other members of the research group of Yaroslavl state university of name P.G. Demidov


Egorov S.V. in his research has carefully studied theoretical bases and practical principles of construction and work of a mobile network in various operational systems (Windows, Linux, FreeBSD) and has offered own technique of construction of practically significant safe mobile network, and also its updating, management and support. All these problems are closely interconnected and especially actual in a view of universal transition to use of report IPv6, and also the strongly pronounced tendency to qualitative change of a network infrastructure.
Being guided by own technique, the researcher had been successfully created and tried in work laboratorys experimental stands. They easily give in to updating and consequently without special work can be introduced to application in various fields of activity of a society.
The report on work is executed at the highest level (88 pages, format A4, 12 font), and it is a unique source of the information of a similar level on the given subjects and, plus to all, is written in Russian.

Insight in past


In the beginning of 2005 Egorov Sergey has carried out research on a theme "Construction of a mobile network in IPv6". It has served as the first mark of interest of the researcher a problematic of mobility. The given work included consideration of stages of adjustment and check of working capacity of a mobile network in which all units work under control of OS Linux. As in the work considered above of any unit did not work under control of OS Linux the given initial research, undoubtedly, is addition to above and allows to create mobile networks of any complexity on the basis of the operational systems most popular in the world (Windows, Linux, FreeBSD).


Behind more detailed information (consultation on the given subjects, introduction of results of research in various spheres of a life and activity of a society, any help in configuring mobile IPv6 networks, the publication of partial results of research) directly address to the researcher or to experts IPv6 of the Forum. You can also ask your questions online.
