Re: [Tinyos-help] Problem with DEFAULT_LOCAL_GROUP on TinyOS 2.1.2
Hi, about BaseStation, it uses Snoop Component and for that, it snoop all packets, about the node ids, it shouldn't do it. 2013/1/3 Kumar, Vimal (ST-Student) vk...@mail.mst.edu Hi, I was testing DEFAULT_LOCAL_GROUP on TinyOS 2.1.2 for which I wrote a simple application with two motes bouncing a message back and forth. The motes received each other's message when they had the same group ID but even when they had different group IDs. I set the group IDs in the make file using the DEFAULT_LOCAL_GROUP directive. I can see that the group IDs are set correctly in the transmitted packet but the receiving node does not discard messages with different group IDs. Same thing happens with the BaseStation, which also does not make any distinction between group IDs. Is this a known issue or am I doing something wrong here?

Re: [Tinyos-help] Problem with DEFAULT_LOCAL_GROUP on TinyOS 2.1.2
Hi, first sorry for this misunderstanding, I wanted to say that this phenomenon in the BaseStation is due to the Snoop Component, but if the applications nodes does not use the Snoop Component, it must be a filter Group ID. Once years ago, we had the same conversation with this topic: http://www.mail-archive.com/tinyos-help@millennium.berkeley.edu/msg39173.html Regards, Antonio Rosa. 2013/1/4 Eric Decker cire...@gmail.com On Fri, Jan 4, 2013 at 12:30 AM, antonio rosa antoniorosarodrig...@gmail.com wrote: Hi, about BaseStation, it uses Snoop Component and for that, it snoop all packets, about the node ids, it shouldn't do it.

Re: [Tinyos-help] Problem with DEFAULT_LOCAL_GROUP on TinyOS 2.1.2
Hi Eric, I have submitted the bug report. Using different channels is definitely a better way to isolate apps than group ids and I will be using that now. Thanks you very much. Thanks Antonio, for pointing me towards that useful conversation.

Re: [Tinyos-help] Problem with DEFAULT_LOCAL_GROUP on TinyOS 2.1.2
Sounds like a bug. can you submit a bug report at https://github.com/tinyos/tinyos-release/issues. You'll have to get a github login if you don't already have one. There is filtering code that is supposed to deal with that in the AM stack. So either there is a problem in the documentation about how to use GROUP or the code has a bug. GROUP hasn't really been used that much. Not sure how useful it is. Because power is very important so transmitting and receiving on the same channel messages that you aren't interested in is pretty wasteful of the receiver's energy budget.
