The advertisement message you are referring to is for meta-data
exchange. This meta-data lets nodes know what their neighbors are
missing or can provide. It is difficult to give one or two sentences on
how and when this advertisement message is sent out. The Deluge paper
does a very good job in explaining this (The Dynamic Behavior of a Data
Dissemination Protocol for Network Programming at Scale).
Thank you

Dear Mike and Razvan and the rest of the members of TinyOs list,
I had put a mail some days ago requesting about explanation of Deluge
working. I got reply from Ryan but he said that you guys would be able
to explain it in a much better way, so please help me out. Here is
precisely what I want to ask.
I have been going through the code of DelugeM and one thing I did not
get was the sendAdvMsg. What exactly is this advertizing message and
when precisely is this send by one mote to another. I mean when do we (
the user) knows that an Adv msg has been send by one mote to another.
What is the purpose of this message in Over-air-programming. Based on
this technique, can I do some modification in the DelugeM component so
that as they send the Adv Msgs across the network, they also send the
timesync messages so that periodically, all the nodes get synced with
each other.
Please guide me on this as it is very important for me....
Regards,
Vishal
