Comparison of forwarding strategies in internet connected MANETs
Erik Nordström, Per Gunningberg, Christian Tschudin · ACM SIGMOBILE Mobile Computing and Communications Review · 2004
For efficient Internet Connectivity in MANETs, multiple gateways and potentially multi-homing and hand-over need to be supported. We compare two forwarding strategies; default routes and tunneling to gateways. We find that tunneling is more efficient and flexible compared to default routes. In fact, we show that default routes will not operate correctly in some situations, particularly in multi-homed networks with more than one gateway.
