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

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
