HI i m working on WSNs my algo requires flooding a message to all the nodes periodically. on receiving the message by a node , its coordinates decides whether it should be made a dissemination node or not. kindly suggest me how to start with this i mean which classes and methods are required for this, and in which file i should implement it. like which thing in .cc file and which in .tcl file. this is somewhat same as TTDD ,if somebody is having the code for the same plz send it also.
