Mannasim or Just NS2?

One of the group member shows two paper on WSN simulation using just NS2 (without mannasim). I told him that I also found a paper on WSN simulation using NS2 and Mannasim .

So come a question in mind.. to use Mannasim or just NS2?
What is the main criteria to determine which one to choose..
If our work can be done without mannasim why border using it?

We are actually going to play around with the routing algorithm, so do we need mannasim?

After 30 minutes discussion, currently our decision is to extend NS2 for the routing part. Work focus on routing algorithm, extending NS2 a little bit on the routing protocol is enough. While at the same time trying to do the same thing for Mannasim (or we can do it later).

The difference between this two option (from my understanding) , Mannasim have more module such as CN, CH , temperature , battery etc. For routing we feel that NS2 is enough.

Waiting for project meeting with another group members to discuss on this.

In this team , my main function is more on simulator studies , suggesting which simulator to use, the syntax , simulation script structure , how to use the simulator. I'm not the one who do all the simulation (I am busy with something else, of course ^_^).

So I'm really sorry for anyone who sent me emails asking for source codes , please find it from mannasim website, my friend said the two examples given works well. Try to have a look at the script, it is quite structured and procedural , refer to a tcl book on calling and creating procedures then the program flow will become very clear.

NS2 is originally for wired network, then it is extended to wireless , Mannasim is extended from wireless. Setting up WSN nodes is quite same as setting up a wireless node but of course it is extended, more object needed.
