hi i am working to add a MAC framework in ns-2 with following properties 1) i need to make a cluster with two types of nodes( types in terms of priority, 1 is transmitter and other is transceiver) and a sink node 2)on sink and source nodes i need to configure PNRG (pseudo random number generator strategy) and nodes need to share their seed value, node ID etc with sink so that sink can schedule transmission schedule for nodes. how to make it work on ns-2 ? i am attaching my paper please suggest how to start coding for it in ns-2. Regards
