[ns] Streaming MM content to mobile nodes using UDP

[Varrian Hall]

Hello,
    I've currently run tests and proven that udp can transmit from wired to
wireless nodes via a base-station, but not the other way around.  I proved
this by changing the agents TCP and TCPSink in the wireless2.tcl file to
UDPmm( a modified version of udp for multimedia) and running tests.  My
scenario involves streaming video to mobile clients and clients replying
back with acks or other control information.  When the source video starts
on the wireless side, no udp packets reach or are passed on by the
base-station.  When the source video starts on the wired side, the mobile
node receives pkts and replies back with acks, however, no acks packets are
passed on by the base-station.  Does someone have a udp module that behaves
like TCP, and should I modify the udp code to have the same controls in the
TCP code?

thanks,
