... • In sequence-number-controlled flooding, the packet forwarding does not follow a specific path. It rather depends on the timing of p. In this example, if the packet from R5 is received at R6 earlier than the packet from R2, R6 will forward the packet to R2. Similar to sequence-number-controlled flo ...

Cellular IP: A New Approach to Internet Host Mobility

The primary design goal for mobile host protocols is therefore to allow for a host to change its point of access without being reconfigured by the user. This requirement is often referred ...
