Hi Ben,<div><br></div><div> Thanks for your help. The laptops are connected over wifi adapters. I have ensuring about the route through the protocol information (as illustrated in the attached figure). How do I use the LinkQualityMult parameter on each node in OLSR version 0.5.6-r2?</div>
<div><br></div><div>Best regards,</div><div>Ricardo.</div>

How are the laptops actually building the connections w/ each other? I.e. over their wifi adapters, or over a wired LAN?<br><br>Also, how are you ensuring the route N1 -> N2 -> N3? If the laptops are meshing wirelessly, it may be difficult to ensure OLSR actually choses your desired route, due to transient fluctuations in wifi signal quality.<br>
<br>If you are not already doing so, I would recommend using the LinkQualityMult parameter on each node specify negative biases for the node(s) you do not want to be that node's next hop.<br><br><div class="gmail_quote">

<br></div><div style="color:rgb(34,34,34);font-size:13px;font-family:arial,sans-serif">I've been working with OLSR protocol and I want to reproduce a scenario with multi-hops. I'm using iperf to generate traffic data packet in the network.</div>
<div style="color:rgb(34,34,34);font-size:13px;font-family:arial,sans-serif">In my tests, I'm using three notebooks with backtrack linux (backtrack 5 R2). Every notebook (nodes), I labeled by N1, N2 or N3. N1 can communicate with N3 only through N2, in multiple hop way. Every node is running OLSR protocol. I try to run the iperf as a server in N1 ($ iperf -u -s -p 5000). In N3, I run the iperf as a client ($ iperf -u -c <IP_address_N1> -p 5000). In the node N3, I just run the OLSR protocol. In a single hop, I have no problem, but in multi-hop it doesn't work. OLSR is finding the multi-hop correctly, but when I try to send the data packet I get the "WARNING: did not receive ack of last datagram after 10 tries" error.</div>
