c++ code for trust based clustering technique in manets

uh, I think you're missing quite a bit in there. Like an actual question, and details about it...

First off, the statement makes no sense. What are 'manets'? What sort of trust calculations are used for them? Why do you need such calculations? And most of all, what have you done so far on the problem yourself?

After a bit of searching, I am assuming you are referring to MANETs, 'Mobile Ad-Hoc NETworks'. All well and good, but the term is hardly well-known; a bit of clarification could have been useful there, or at least a full sentence would be nice. It would also be useful if you could explain what sort of 'trust calculation' you have in mind. But that isn't the real problem.
