hi all,
i'm studyin vertical handover so i installed the nist mobility package. i
run the wifi-wimax.tcl script
that implement a vertical handover between wifi and wimax. the siulation run
but the problem is when
the node is attached to the wlan network there is is no transmission between
the AP and the node
because the synchronisation faile as mentionned in the line above. so if
someone can help me fix this
i will be thankful.
these are the line i get in the command prompt:
