Re: [ns] error while building NIST extension
Mariem, The new compilers do not like to see the class name in the include files. To fix it, just remove the "Mac802_11::" in the definition of the calFreq function. You may have to do that in other files as well.

Re: [ns] how to improve maodv
This is a difficult problem. The origin TCP problems in MANETs (with any routing protocol, multicast or not) is the interpretation of facts by TCP. TCP has the sliding windows technology which reduces the amount of data sent to the destination each time it not receives ACKs as expected. So, in a wireless network there are frequent collisions and packet losses by the nature of the transmission, and TCP interprets them as congestion, reducing the sliding windows (and the performance). Nitin Vaidya wrote a classic paper about this problem. I suggest you read this paper, so you must give some inspiration.
