[ns] Asking about configure snoop protocol in wired cum wireless architecture
I have configure script for snoop protocol in wired cum wireless
architecture, but i always failed and got segmentation problem..
can you help me about this problem?
this is my script (just main scenario):

[ns] Fwd: [Help] About configure snoop protocol in wired-cum-wireless architecture
Dear all, I want to asking how to configure script in ns-2, if we wanna implement's snoop agent at link layer in ns-2's wireless network, because i've always failed, if i implement snoop agent in wireless node that work as base station (the problem is : segmentation fault).. but if i simulate snoop agent just in wired network, it works.. i'm using ns version 2.33 as my simulator and simulate wired-cum-wireless network architecture Thanks for attention..
