Detailed Description

AODV chain regression test.

This script creates 1-dimensional grid topology and then ping last node from the first one:

[10.1.1.1] <– step –> [10.1.1.2] <– step –> [10.1.1.3] <– step –> [10.1.1.4] <– step –> [10.1.1.5]

Each node can hear only his right and his left neighbor, if they exist. When one third of total time expired, central node moves away. After this, node 3 doesn't hear any packets from other nodes and nobody hears his packets. We want to demonstrate in this script 1) route establishing 2) broken link detection both from layer 2 information and hello messages.

 Expected packets time diagram.
