(My feeling is that I actually will get a grip of the Contiki faster!) Build system - TinyOS, very nice when you have understood it (platforms, sensorboards, chips, ...) - chips is a very good abstraction! - Contiki, buildsystem that can be invoked from simulator have not seen enough to judge it fully yet... (platform, cpu) Repository - TinyOS, Subversion can do some things CVS can't (but some doc. still refers to CVS) - Contiki, might have a painful transition in future... (but CVS works) Code quality - TinyOS, I am not convinced... It is quite difficult to write source that makes good use of existing interfaces, while avoiding taking shortcuts to platform modules. - Contiki, have not seen enough to judge it yet... (but what I have seen is a bit below my expectations) Developer Tools - TinyOS, on two foots - is its main tools Java or Python? (my guess: was java, now moving towards Python - or?) - Contiki, Cooja simulator is really great - once you understand that you should use it. Have not seen enough to judge other parts yet... Resulting system - TinyOS, I really recommend turning up optimization at least on platforms with more program flash. The preprocessed source is a file full of small C functions and _with_ inlining the resulting code can become quite effective. Remember: faster code = fewer CPU cycles = lower energy consumption (if total memory accesses is kept in contol) i.e. -O3 might be a better option than -Os... - Contiki, have not built anything for actual hardware yet /RogerL -- Roger Larsson, Research Engineer Division of Mobile Networking and Computing Luleå University of Technology SE-931 87 Skellefteå Från: tinyos-help-boun...@millennium.berkeley.edu [tinyos-help-boun...@millennium.berkeley.edu] f#246;r Pablo Marcos Oltra [pablo.marcos.ol...@gmail.com] Skickat: den 15 november 2010 17:58 Till: Wahid; tinyos-help Ämne: Re: [Tinyos-help] TinyOS vs Contiki Hi Wahid, I ended up using TinyOS because of the documentation and the community.

Hi, There is a course going on at KTH, sweden on Sensor Networks given by Adam Dunkels, Luca Mottola and Olaf Landsiedel, with some good info on the OSs for WSNs. In my opinion, if you plan to do hardware implementations with the motes use TinyOS since the documentation for TinyOS is much nicer. Contiki as a fantastic simulator that TinyOS doesnt have. http://www.ee.kth.se/~oland/teaching/wsn2010/index.html Best, Jose Hi Wahid, I ended up using TinyOS because of the documentation and the community.

Hi, The Cooja with TinyOS is not yet 100% bug free but maybe it works 100% well for some things. Worth a try!

Re: [Tinyos-help] TinyOS vs Contiki
Hello, For a while I have been using Cooja quite successfully with TinyOS. There had been a couple of issues, for example on the serial stack and another one with the timers, but with the help of the Cooja guys we could resolve these quickly. Use the cvs head of Cooja (in the Contiki cvs) to make sure that you have the latest version. Documentation is still somewhat limited, especially on TinyOS. I know that the guys at SICS are working on this, so I hope this will change eventually. Best wishes, Olaf Live as if you were to die tomorrow. Learn as if you were to live forever.
