Receives a multicast message and check if this message has to be forwarded
We should get the headers and check if we have to forward the message
We do not send the message for ourselves, since it should have been sent
in the OMOLSR protocol up method
Sends a new message to all direct neighbours in the multicast group
(and another message to the local node) with application data and
header information about the remaining nodes which the message
must be delivered to
A common mechanism is employed for populating the local link
information base and the neighborhood information base, namely
periodic exchange of HELLO messages.
This class is in charge of performing all needed actions when a new
HelloMessage is received
Tables (Mpr,MprSelector,Neighbour of Neighbours) are updated when
a new message is received
MPR computation is asked to be performed again when a neighbor becomes
symmetric neighbor or we add a new two-hop neighbor
OnTableChange is invoked when a new entry is added to the neighbor table
or when there are new NoNs
The "Originator Address" of a HELLO message is the main address of
the node, which has emitted the message.
