MIH implementation

The goal of this article is to describe the ongoing implementation framework of the emerging 802.21 standard in ns-3. If you arrived here following your high curiosity line, that's great but assure that you have first read a few documents regarding that draft standard.

Tasks completed so far

By now, the following MIH blocks are implemented:

• An abstract MIH_LINK_SAP and its primitives
• An abstract MIH_SAP and primitives for MIH processing on the local stack only

Ongoing development

The following tasks are being held currently:

• Implementation of the MIH_FUNCTION for local MIH events and commands exchanges:
  • Link events delivery from MIH_LINK_SAPs to MIH_USERs (through MIH_SAPs)
  • Command delivery from MIH_USERs to MIH_LINK_SAPs

Foresights

In this section, you will find various components that are still needed to have start some MIH framework tests.

They are presented in their order of priority:

Local MIH exchanges

• Integration with WifiNetDevice and WimaxNetDevice
  • WifiMihLinkSap -- ready to be done
  • WimaxMihLinkSap -- until Wimax is validated
• Examples of MIH Users entities:
  • A simple application is to be defined later.

Remote MIH exchanges

• The MIH Protocol including:
  • Packet TLV formats
  • MIH message header format
  • Transport of MIH messages over L3+ plane
• MIIS
  • RDF schemas
