32 *
33 * \brief AODV chain regression test
34 *
35 * This script creates 1-dimensional grid topology and then ping last node from the first one:
36 *
37 * [10.1.1.1] <-- step --> [10.1.1.2] <-- step --> [10.1.1.3] <-- step --> [10.1.1.4] <-- step -->
38[10.1.1.5]
39 *
40 * Each node can hear only his right and his left neighbor, if they exist. When one third of total
41time expired,
42 * central node moves away. After this, node 3 doesn't hear any packets from other nodes and nobody
43hears his packets.
44 * We want to demonstrate in this script
45 * 1) route establishing
46 * 2) broken link detection both from layer 2 information and hello messages.
47 *
48 * \verbatim
49 Expected packets time diagram.
