Another student is working on a DyMo implementation. To pave the way for implementation of different routing protocols and to see whether DyMo works better than AODV in the typical SunSPOT scenarios. His blog is located at <http://patsstudent.cmi.ua.ac.be/~bsas/sunspots-on-dymo/blog/

Bart,

I just took a look at your student's blog and noticed a recent entry where he describes his difficulty placing SPOTs to achieve a desired network topology. If he is using the Red SPOT SDK then he can use the MAC-layer filtering that is already in it for just that purpose. Could you please forward this email to him? (His blog does not include any contact information.) Thanks.

-- Ron --

p.s. all the filtering code is in com.sun.spot.peripheral.radio.MACBase.java in spotlib.

from the Release Notes:

red-081117 introduced:

# To make it easier to control the radio connectivity of a group of SPOTs, the MAC layer can now be set to throw away any packets from senders not on a SPOT's white list. Actual routing is still be done by AODV as it is now.

To use it set "radio.filter" to true and "radio.whitelist" to a comma separated list of radio addresses, where only the low part of the addresses need to be specified, e.g. "2DFE,1234" => only receive packets from senders with an address of 0014.4F01.0000.2DFE or 0014.4F01.0000.1234. The properties are read when the SPOT starts up.

and red-090219 added:

# Display packets received/sent by toggling the green/red processor board LED, also like the basestation does, by setting the system property "radio.traffic.show.leds" to true & reboot the SPOT.

# Added option of setting a blacklist to MAC-layer packet filtering. Uses "radio.blacklist" property. Only used if "radio.whitelist" property is not defined.
