[Tinyos-help] Application of dynamic address allocation

[Jacob Sorber]

Are you looking for a full dhcp-style application or do you want to know how
to change the mote's address?

Changing the mote's address should be easy.  At least in Tinyos 1.x,
TOS_LOCAL_ADDRESS is just a variable (uint16_t).  So, you should be able to
change its value at runtime.  I haven't ever needed to do this, but from the
code I don't see any reason why you couldn't.  Try it out and see.

As for doing dhcp on motes, I don't know of any existing application that
does this.  I'm sure you can do it, but I don't know that you really want
to.  If you could give some details about what exactly you need, it might
help.  What kind of addresses are you assigning?  2-byte TinyOS addresses?
IPv4?  Do you need to be able to uniquely identify your nodes (i.e. do you
need a unique node address (like a MAC address) as well as the dynamic one?

Anyway, hope that helps.
