void ns3::aodv::RoutingTable::InvalidateRoutesWithDst ( std::map< Ipv4Address, uint32_t > const &  unreachable)

Update routing entries with this destinations as follows:

  1. The destination sequence number of this routing entry, if it exists and is valid, is incremented.
  2. The entry is invalidated by marking the route entry as invalid
  3. The Lifetime field is updated to current time plus DELETE_PERIOD.

bool ns3::aodv::RoutingTable::MarkLinkAsUnidirectional ( Ipv4Address  neighbor,
Time  blacklistTimeout 

Mark entry as unidirectional (e.g. add this neighbor to "blacklist" for blacklistTimeout period)

neighbor- neighbor address link to which assumed to be unidirectional
blacklistTimeout- time for which the neighboring node is put into the blacklist
true on success
