Project goals

• Goal 1 Service Extension to provide existing
  and emerging IP-based applications and services
  for mobile users without direct access to the
  fixed networks.
• Goal 2 Ad hoc Integration to propose an open
  architecture for the interaction of Radio Access
  Network (HotSpot, GPRS/ UMTS ) and Ad hoc
  networks.
• Goal 3 Mobility Support to support mobility in
  heterogonous radio access networks.
• Goal 4 Billing Charging to design a Billing
  Charging methods for IPonAir.
• Goal 5 Computer Simulation to develop a
  framework for the performance evaluation (TCP/IP,
  Handover, Interworking and Interaction) by
  simulation tools.
• Goal 6 Trials to test the developed functions
  (Service Extension, Mobility support) by
  practical means.

Terminology and definition

• WA-GW Wireless Ad hoc Gateway, owned by network
  operator.
• (Stable, controlled, not moving during
  communications.)
• MA-GW Mobile Ad hoc Gateway, owned by an
  enduser.
• (Instable, uncontrolled, moving during
  communications.)
• HS-GW Mobile HotSpot Ad hoc Gateway, owned by
  the network operator.
• (Stable, Controlled, moving during
  communications.)

Design principles

• Minimize the requirements on the RAN
• Minimize the requirements on the user terminals
• Use user plane to transport control information
• Minimize the signaling traffic
• Be independent on any radio interface
• Be independent on any specific protocol
• Be compatible with other Internet protocols
• Easy deployment and evolution
