I think you still misunderstand the purpose of the OLSRd daemon. Its a pure 
routing daemon that decides about forwarding rules to other nodes and tell the 
kernel about it.

It's neither designed nor able to handle unicast traffic of the network. One 
reason an OLSRd mesh is pretty fast even on slow hardware is that the traffic of 
the network does not need to be transfered into userspace.

The only thing I see what you could do is to write an OLSR plugin that somehow 
controls your local firewall to block of unwanted packages. But even then an 
attacker would just spoof his IP address.

Using IPsec for unicast might be the better sollution.
