NS2 - Sensor Networks

I need NS2 implementation of any published journal paper on Sensor Networks Routing Protocol for QoS. It can be any published paper meeting following conditions (1) it should be relatively new i.e 2009 onwards. (2) must be from a journal of impact factor. This project is for someone who already has a working code available in NS2 along with the published paper. In your bids you can send me the papers for which you have the code already available, if the paper is good enough I will award you the project and then you can send me the working NS2 code. Please note that the code does not need to be developed in this project. In Phase 2 of the project (new project) I will employ the freelancer to implement a specific paper, which ofcourse would be paid accordingly. regards
