Zoltán Zörgő: i need you help please reply as soon as possible

Zoltán Zörgő:My question is that.How Base station authenticate with the satellite?Is any procedure exist for trust relation ship between Two base station? how a base station keep account of other base station time to time?How one base station keep information related to mobile users of neighbor base station to perform secure rooming of mobile user from Old base station to new base station?Only i will focus on layer 2 of OSI model.I want to show diagrammatically methodology.Please help me.Basically i am confuse where these protocols will lay in a layer frame work and how?

where r u?i need your help

hello

can you suggest to me how i start writing on literature review.because in introduction i write about IEEE 802.11i,i do not find any more detail on IEEE 802.11i.In literature review how i start.In my mind first write about Wireless LAN,than about security (mostly security work done on data encryption,denial of service attack, main-in-the-middle attack )work which already done, than tell about handoff.because on basis of literature review the methodology will be define broadly.Please help me

no one helping.I am going to left my Mphil. No on guiding and Helping.

Thank you so much.Now Skype is working well

some on help me.i am trying to prepare my thesis proposal but i am failed.oh God what i do?oh God

radius server can give certificate to the access point.can you tell me at which layer radius server lay?access point and switch lay on layer 2.i want to limit my work at intra-subnet,and layer 2 handoff will be considered and basic service set (BSS) will be considered.Basically i want to do work on " enhancing efficiency for secure handoff in IEEE 802.11i wireless local area Network "because during handoff many researchers do working on latency of handoff.i want to introduce a security concept in handoff.so i noticed that main roll play by access points.so there must be some mechanism need.please help me ,give me some suggestion ,how i make my work best.

in my laptop i installed Skype.it was working well.but problem is coming in voice.no one can listen me and also i can not listen to others.voice driver is installed.you-tube videos voice is coming.what i do,how i resolve that problem?

Tell me about yourself

hy i am missing you

if you have any information,any search engine you known about for searching best material or any best link related to networking.Please share with me.because Knowledge is necessary to achieve some thing.

Thank you.if any problem i face can i asked from you?

only correct my proposal once it will approved than i will do work my own-self.Only i need guidelines.

i am depressed .Please not leave me alone.I am failed every time.my hope is finishing day by day.

Zoltán Zörgő:please help me ,how i correct it.how i change it please.can you tell me what is difference between access point and router.you tell about neighbor discovery and handoff protocol is it exixting or not.if not than can i make it.Any simulator will make for it or not? in neighbor discovery protocol what means sending packets on wireless interface and where neighbour information will placed?what type of data will exchange over the wired backend.Because i think so access point memory is not so much large to keep information about neighbor client's and access points.What you think?where step 1,2,3 protocol will plcae?in access point or in Radius server?who will give the authentication certificate to the access point?is authentication certificate will placed in every access point own memory for ever?Please help me tomorrow is proposal submission day.I am very very depressed.

Zoltán Zörgő:can you correct it for me.Please tommorrow is my proposal submission day.
Problem Statement:
This research work is addressing the authentication process of access points to deal with secure handoff process in multiple Access Points (APs). There is a need to develop a new mechanism which will allow an authenticated seamless handoff between two APs.
Scope:
This research work will focus on authentication process between access points (APs) to ensure seamless handoff between two access points. Access point IEEE 802.11 a\b\g technology will use. A Wireless Access Point is supporting these technologies simultaneously [6].
Methodology:
Formulation of Layer Framework and it will be consisted in modular form. IEEE 802.1X technique will be adopted. Cryptographic Method will be used for authentication of access point. It will help to provide a seamless handoff between access points.
The Layered Framework will be consisted on following Module:
1) How to establish inter-AP trust? Supposing you are in an infrastructure with wired backend, you can use RADIUS and certificates to authenticate AP-s, thus every AP can verify the authenticity of it's neighbor.
2) Neighbor discovery protocol (like CDP, but over wifi). From time-to time, every AP is sending out discovery packets over it's wireless interface and keep account of it's neighbors. The data exchange itself should be done over the wired backend.
3) Handoff readiness protocol: every AP would be informed over the wired network about the clients known by it's neighbors. Thus every AP would know about all potential rooming clients. A client already authenticated by one AP can be trusted by the other ones too. This can be also used to move current encryption key from one AP to the other during rooming.

Please help me you know show me the right path.Oh you are great o my God.How i thank u.You are great ad visor.Please help me more until i am not completing my thesis.Can i consult you every time when i need your help.

yes you are right.this is true methodology.Yes this is my methodology.can i use it in my thesis proposal?Know according to it what will scope and problem statement will be make?is it new work any one perform it before which you send me?

Zoltán Zörgő :i read the pdf file which you have sended.Its nice.In that document i noticed that all work has only done for mobile user's.focusing on reducing the handoff Latency for users.i did not find any authentication between two access points.why some one discussed on that topic.The cross layerd frame work is proposed in that document.what is difference between layerd and cross layerd framework.My serching is not good.I want to find a material on my topic but could not find.I am stuck in methodology and literature Review.My teacher was said to me make a literature indirectly,i can not perform directly work.I am much much confused and worried because tomorrow is proposal submission day.If i did not complete it than this year will be waste of my study. than i can start next year.I am much worried.

Some flow in my mind,i do not known its correct or not?Like example old access point want to perform a secure handoff -> old access point will check in memory about listed access point MAC address-> old access point than chose its nearest new access point->old access point than send handoff input to new access point and also demand an identity or authentication certificate means to check, it is a trusted access point or not-> so new access point will send its identity to a old access point->old access point check in its memory about it validity if valid than a mobile station will be handover to the new access point other wise canceled the hand over process.New access point can also demand an authentication certificate from old access point before receive a new mobile station in its cell.

basically my advisor will demand a simulator at end of thesis.I am now working on proposal.If i mail you my proposal than can you help me?to define a better Methodology.My teacher said to me explore the methodology.Because monday is last date of submission of proposal and now sunday is start.My own wish is that make a theoratical solution and not remains a need of semulator.i don not like codding its my weak point.

I am very very depressed.I am working on that problem, i am failing every time.GOD help me what i?

Zoltán Zörgő:ok i explain you.you notice that one access point make a cell in infrastructure mode.access point is working like a base station.it is providing services to the user's or mobile station.when mobile station is moving from one cell to an other cell then handoff occur from old access point to a new access point.mostly security issues are coming in wireless LAN.i want that first a trusted relation make between old and new access point, after built a trusted relation then handoff will be occur of mobile station from old access point to a new authenticated access point.I am doing this all due to security purpose,you know that rogue access point ,it is un-authenticated access point.it is also causing deniel of service attack.so if a solution proposed for that problem.My thesis will be complete and i will get Mphil degree.I want to make a frame work or a protocol for that problem.I donot know what will good solution and how make a framework or aprotocol.Basically no one provide a good guideline to me.Every one hiding its information.If peoples have any information about that problem why they are not sharing with others.If i make a success full person than i will make a special website for students of IT and i will provide information and help them.

Zoltán Zörgő you are great.please help me what i do?I need information on the above define topic.Please can you tell me that to solve the authentication process between two access point,can a frame work proposed or not how i propose it?
