Hi all!,
I am working on a solution for wireless remote data acquisition The
remote device runs embedded linux mounted on a Compact Flash and is
connected to a set of peers by standard wireless ethernet
transponder(802.11b,using adhoc mode).I need to stream the data on to a
basestation,by multihop routing.(which could be another peer)Since the
data is sensor information,I need to transfer this reliably too.
1. Do I need to build an database server(like SQL),build a database and
stream data through a web server??Will this be a huge footprint??Can I
stream data by using this??will this work in an adhoc scenario??Also I
can use it to transfer data both ways right?
2.Does anyone have an idea of a modbus interface???I heard it is used
for all handheld/embedded data acquisition.
3.If I dont use a database...How do you buffer data in the case of a
network outage/limited connectivity....???
4.Suppose I timestamp data and write it to a file and then ftp them,is
there a better way to do this?
The tools I can play with are Python,C or C++..
Thanks in advance!
