For BSM application, WSMP if enabled in the transport layer, the communication is direct from source to destination. And for this reason in NetSim WSMP handles all Transport and Network layer functionalities. Network layer protocol - IP and routing protocols - AODV, DSR, ZRP, OLSR don't have any role to play.

Users should disable WSMP in the transport layer for AODV, DSR, ZRP or OLSR to run.
