Subject: [manet] Problem with GloMoSim ODMRP Simulation

Hi,
 
I am student, testing the ODMRP simulation code that comes with GloMoSim 2.0, but there seems to be some problem with the ODMRP implementation.
 
1) When I simulated a standard environment (300S, 1000 x 1000M, 50 nodes, 20 member, 1 source, uniform node-placement, no mobility, radio range = 250M), only the nodes within the radio range of the source node received the multicast data. Nodes far from the source received nearly none of the multicast data. (Actually, for those nodes, Number of Data Packets Received =  Number of Join Queries Txed << Number of Data Packets Sent by source). The conclusion is that the intermediate nodes are not forwarding data packets, i.e. the MESH has not been successfully set up.
 
2) I tried to run the same program with the GUI, the location and interactions among nodes confirmed what I discribed in 1). 
 
I am sure many people have successfully simulated ODMRP with GloMoSim and I am a newbie for GloMoSim and ODMRP. I must have done something wrong. Could anyone help me?
 
Thanks a lot!
 
Best regards,
Caoyu
