Hi,
no one of the wireless people has asked for mentorship at the Google
Summer of Code yet, so no one can see the 3 wireless applications. I
copy them below, but note that they do not look great. If you are
interested, register as mentor for the Linux Foundation on
http://www.google-melange.com/, and as soon as you get the approval from
me, score and comment ASAP.
If you are not interested at all, please tell me ASAP so that I can
simply reject the applications on your behalf.

Mentor: No mentor assigned
Short description: Improve 802.11n adhoc support / stability and
throughput specifically for better mesh networking. This would help
projects/communities such as freifunk, batman-adv and the Village Telco.
Name: Rudolf Meijering
University: University of Stellenbosch / Electronic Engineering with
Computer Science
Short bio / overview of your background:
Started using Linux when I was 13 years old. Used Red Hat Linux,
OpenSUSE, Ubuntu and Gentoo as desktop distributions. I took computer
science as subject at school and had extra programming classes after
school. Started studying Electronic engineering with Computer Science as
major in 2006. I did numerous holiday jobs including Linux kernel boot
time optimization, boot loader optimization and driver initialization
time optimizations.
Email: [email protected]
IRC: irc.freenode.net sKAApGIF
What platform do you use to code?: Ubuntu 11.04, x86_64 (Intel i7),
OpeWRT trunk, TP-link wr1043nd, wr743nd and Village Telco 'Mesh Potato'.
Coding Languages / Skills:
Experienced with:
C 3 Semester courses, Wrote basic functionality OS for
x86 qemu
C++ 1 Semester course with weekly tutorials / projects
Java 3 Semester courses including advanced data structures,
algorithms
Python Wrote Web Shop concept prototype in Django for holiday work
Touched and played around with Perl / Bash scripts, mostly for
init and configuration scripts
Required experience:
C - very comfortable with C especially low level programming such
as drivers.
802.11 basics - I started the Stellenbosch Wireless User Group.
Setup my own wireless mesh network. Flashed more routers with OpenWRT
than I can rememeber and I have a strong background in the mathematics
of wireless communication (rf propagation, multipath, antenna
directivity / gain).
I have built the snapshot ath9k drivers numerous times for 802.11n
stability and throughput improvements.
You and Us
I'm actively involved in the Village Telco (Wireless Mesh Networking
Infrastructure), providing mailing list support, participating in
workshops and testing hardware / drivers.
Why have you chosen your development idea and what do you expect from
your implementation?
My current mesh network contains several ar71xx based nodes. Making
improvements to ath9k or linux wireless in general will therefore
provide direct benefit to myself. In addition from my participation in
the Village Telco I have become aware that the Village Telco could
greatly benefit from 802.11n, but unfortunately driver stability and
performance is currently keeping them from transitioning to better hardware.
What do you want to achieve?
Improve 802.11n ad-hoc support and throughput in ath9k and ath9k-htc.
Re-introduce VAP support for multiple ad-hoc/managed vap's per radio.
What makes you suited to carry the project?
I have a thorough understanding of 802.11n basics, kernel modules and
drivers and excellent low level C coding skills.
How much time do you plan to invest in the project before, during and
after the Summer of Code? Before GSoC I will have about 1hour per day,
full time during GSoC, and about 2 hours per day after GSoC.
Determine current state of ad-hoc in ath9k and ath9k_htc
Investigate required work to re-introduce VAP support
Re-introduce VAP support and do necessary work to make future code
maintanance easier
Work on support for ad-hoc in ath9k_htc
Improve ad-hoc throughput performance
Perform stability testing / bug fixing / maintenance

While the credential looks inpressive, the goal is not clear.

Improve wireless roaming
------------------------
meet88
Email: [email protected]
Mentor: No mentor assigned
Short description: In this project, I intend to improve user experience
of roaming in WLAN. This can be achieved by making handover schemes
seamless. Also, I intend to provide support which can reduce signalling
overhead over the IPv6-network.
Status: pending
* Name :- Harmeet Singh
* University:- Indian Institute of Technology Kanpur
* Short bio:- I am forth year student in computer science and
engineering department. I have interest in computer networks. At
present, I am studying IEEE 802.11 and other issues which one face in
WLANs. I have done courses in networks and have hands-on experience with
WSN. I posses strong coding skills and knowledge of 802.11 to pursue
this project.
* IRC nick and group:- meet88 freenode
* Coding Skills:- C, C++, Java, Python
In your application let us know
* Did you ever code in C or C++/Perl/python/..., yes/no? what is
your experience?
Answer: Yes, I have done coding in C and python. I have done many
projects in C. I implemented network sniffer in C which can sniff
traffic in ethernet network. I have also developed applications for
android based mobile phones.
* If you apply for a project on our ideas list, have you experience
in the areas listed under "Desired knowledge"?
Your Project
* What do you want to achieve?
Answer: I want to improve experience of roaming in wireless
networks, At present, handover is one of the bottleneck to provide good
QoS in real time application. Also, mobility introduce long delays and
signalling overhead in present mobile-IPv6. I want to implement
techniques which can achieve seamless handover and reduce the delay and
overhead of mobility.
I have chosen this odea because I have studied extensively about
various techniques which can be applied. Also, I have been involved
working in projects related to computer networks. I think, I can apply
my knowledge and skill for the better expeerience of others in community.
I have done experience of developing application. I understand that
designing the problem solution takes time and better solution can be
provided if we know what exactly we are looking for. The coursework and
projects that I have done in my studies make me confident that I can
carry this project and complete it successfully.
I intend to devote 25-35 hours/week to this project.
I intend to begin work on may-4
At first, I would like to design problem solution. For that, I need to
specify requirements of application and decide which technology/language
etc to use to develop it. I would like to start implementing it as early
as possible. I intend to deliver first version by end of may-fisrt week
of june. Then by july first week, I intend to cover major part of
project and start testing by july end. I want to deliver project by
mid-august.

I won't have time to mentor anyone this year.
I do note, however, that the projects aren't really very well thought
out.
The IBSS one is concerned with TPT but somebody else is working on 11n
support anyway, for instance. Also multiple IBSS per HW, which is really
tricky and can only work in corner cases. Overall, I'm not convinced
this is a suitable project.
The second one is just totally useless.
The last one looks a bit like some googling around the problem space of
a basic idea ("improve roaming"), but offers no reasonable indication as
to actually achieving any type of solution, and any actual roaming
improvements wouldn't be in the kernel anyway.
Even if I had time to mentor, I think I'd reject these applications
anyway.
