[Tinyos-help] Application of dynamic address allocation

[Itamar Amsili]

Hi Jacob,

I'm looking for a DHCP-style application, but much simple, which means
assigning a 2-byte address(the TOS_NODE_ID in tinyos 2.x) to a node who is joining a network.
if there is no network in the reception area, the node will assign to itself the default=1, and will continue
searching the area.
if the node finds a nother node, i.e. there is a network around, it will recieve an address to assign 
from the network(depends on how many nodes are in the network already).
It's an Ad-Hoc network,no leader.
this is it in general. it is not so complicated but i have no experience in the NesC code so i need
an example or reference of the operations we take ( initializing, sending & recieving data, timers etc ).
If you have any ideas it will be great.

Thanks in advance

Itamar
