Yep, that's right. We were able to develop a nesC module for trilateration using RLS over known positions and RSSI, and then a complete tracking algorithm using Unscented Kalman Filter, but both in the, plenty of RAM, iMote2.
Now we have moved to another excellent platform, named "econotag", with about 80KB of RAM and have embedded a complete distributed algorithm (consensus like) and a real time voice detector, with multi-thread, UDP over RPL and IPv6. But again this is about 8 to 20 times the RAM size of TelosB or micaZ. One colleague has been able to implement localization and tracking using TDOA in TelosB. But I guess it required him some effort to optimize the RAM usage. Good luck!
