Difficulties in wireless simulation

    What kind of result you are getting? And what kind of result you are expecting? – Just explain briefly.

    What version of ns you are using?

    I am using ns2.33
    I expect to simulate the handover of the mobile node and mainly to observe how the mobility is managed with SCTP.
    I already tried the script in the case of a wired network and it works.
    However, when I use 802.11 at the mac layer, there is no packet transmission between the mobile node and the HA.
    It seems like the route between the MN and HA can’t be defined.
    I have a message “Node(7) is not defined in the array”!!

    First try to reduce the distance between MN and HA and run the simulation.

    I have a distance of ~50m between MN and HA and I tested a CSthresh = 3.5*10-10.
    Also in the trace file, the authentication is accomplished between them. The problem is to establish routes.
    Do I need to use ping to establish routes??
    I found in mtp.tcl that a ping is used to establish routes. Is it an earlier version??
