To The Mentors Improving Wireless Roaming Linux Wireless GSoC 2009 Linux Foundation. Sub: Application for Linux Wireless GSoC 2009 Project. Hi my name is Ashwin Raut. I am currently pursuing my Masters degree at San Jose State University, San Jose, CA,USA in Computer Engineering with Embedded Systems as my specialization. I have done my Bachelors in Electronics and Telecommunication Engineering. I am applying to work for the Linux Foundation Google Summer of Code 2009 project Improving Linux Wireless roaming which involves implementing triggers for efficient AP handoffs. Project Idea: What I think of it is that one way of implementing this is to improve the present background scanning mechanism by making it periodically active. That is the RSSI beacon scan will take place after a specific interval of time say around 200 ms and based on this , the information of the strongest signal AP’s can be collected by profiling the signal strengths from AP’s. So that over a period of time only those AP’s will be scanned that provide good signal strength which is above the predetermined threshold level. If there is possibility that no AP provides signal strength above the predetermined threshold then the scanning will be made broader. This will help in deciding the next best AP to connect to if the signal strength of existing AP is degrading over period of time. So either user can decide what to do or that functionality can also be provided in algorithm. Now this type of active scanning can reduce the overheads taking place in continuous scanning. The triggering mechanism will use the above information and decide when to switch between Access points. There are two important points in this, first the triggering will take place only when the signal strength of the current AP is degrading over a period of time specified by us or if the signal strength suddenly goes below the signal threshold level, and secondly we can also consider the AP selection based on the traffic load on that AP’s as one of the AP determining factors. I would like to implement it mainly in C++ but use any other language like C, Python as substitute or along with it is ok with me. My Background details: I use x86 hardware Architecture with Fedora 9 as Operating system as well as Windows Vista. I use C and C++ for coding. Presently, I am working as research assistant in my university where my principle role is to implement TDMA MAC Layer in Software Defined Radio i.e GNU Radio with USRP hardware. Here I am implementing MAC layer Functionality in Click Modular router in C++ and the wrapping it with Python to port it to GNU Radio in Fedora 9.I am also surveying various MAC layers and localization techniques used in Wireless Sensor Networks. I am familiar with working on Linux character Device Drivers and porting Linux on ARM based embedded systems as that’s part of my degree specialization. I would like to work on this project as this will give me a great opportunity to work on an Open Source project and apply my skills to contribute in its development . I would be available to work full time from 27 th march 2009 as soon as I finish my final exams. I would also like to know more about this project and the application procedure. Please let me know if you need more information.I am very sorry for being so late. Regards, Ashwin Raut MS Computer Engineering, San Jose State University, San Jose, CA, USA.
