21// This script, adapted from examples/wireless/wifi-simple-adhoc illustrates
22// the use of OLSR HNA.
23//
24// Network Topology:
25//
26// |------ OLSR ------| |---- non-OLSR ----|
27// A )))) (((( B ------------------- C
28// 10.1.1.1 10.1.1.2 172.16.1.2 172.16.1.1
29//
30// Node A needs to send a UDP packet to node C. This can be done only after
31// A receives an HNA message from B, in which B announces 172.16.1.0/24
32// as an associated network.
33//
34// If no HNA message is generated by B, a will not be able to form a route to C.
35// This can be verified as follows:
36//
37// ./ns3 run olsr-hna
38//
39// There are two ways to make a node to generate HNA messages.
40//
41// One way is to use olsr::RoutingProtocol::SetRoutingTableAssociation ()
42// to use which you may run:
43//
44// ./ns3 run "olsr-hna --assocMethod1=1"
45//
46// The other way is to use olsr::RoutingProtocol::AddHostNetworkAssociation ()
47// to use which you may run:
48//
49// ./ns3 run "olsr-hna --assocMethod2=1"
