mih.py

A IEEE 802.21-based media independent handover services implementation.

USE THIS PROGRAM FOR EDUCATIONAL PURPOSES ONLY. IT WAS NOT MEANT FOR OR TESTED THOROUGHLY FOR REAL WORLD OR PRODUCTION USAGE. THIS SOFTWARE COMES WITH NO WARRANTY AT ALL, USE AT YOUR OWN RISK. YOU HAVE BEEN WARNED!

Differences from IEEE 802.21

No compatibility at all. This software was inspired by the standard and even has some of it's features, but it was meant to be used in a specific situation on the college I attend.

Assumptions

  • Hardware doesn't change. In case of hardware change (e.g. an NIC disapears), the behavior is undefined. NOTE: point-to-point 3g interfaces don't count, it's assumed they're not permanent.

  • The best link is always the one of the most reliable technology (e.g. wifi > 3g). If technology is the same, the best link is either the one with best signal strength or the first.

  • The 3g Base Station do not support MIH-like services, at least not the one implemented by this application. That means that no peer discovery is done when you connect to a 3g network.

  • There's no other application managing NICs. The program tries his best to keep NIC information updated, but if an external program changes anything the behavior is undefined.

Dependencies

on Arch Linux, run:

pacman -S python2-dbus dbus-glib modemmanager
