Hi,all I saw your document http://www.isi.edu/ilense/software/smac/ns2_energy.html ,and you provide a demo tcl script to evaluate energy comsuming in version 2.29. However ,I recently to do my project which need use version 2.27 . Is there any demo tcl script to simply evaluate in 2.27? Or some ways to revise current script and run in ns2 2.27? Thanks a lot
