Desperate for help!

allke0527,

If you are successfully 😀 installed the NIST code in ns2 and getting some meaningful statistics and results, then your problem probably will not be in Otcl or tcl. You have to find the section of ‘c’ code which is handling the Hanover process and add your scheme in those sections.

The location information of nodes can be resolved in side the ‘c’ code or tcl simulation script(using X_, Y_ and Z_ values at an instant).So we can simulate GPS using a single function. (The neighbor information which we may require during finding location information can only be resolved in c code; tcl neighbor detection function will not work in wireless scenario)

Help with that or any code example about modification of the source file can be obtained after little effort on google(try keywords 💡 such as “ writing new agent for ns”, “new protocol for ns”). But, anyway, implementing our own handoff strategy in NIST code will take lot of time and effort 🙁 .
