Dear list (impersonal, yet true),<br><br>We have been working with OLSR for some time now and have come up with the following problem: <br><br>OLSR loses routes when traffic other than the OLSR packets is on the network. Our OLSR packets (UDP port 698) are being prioritized over all other traffic; this doesn't help. We suspect the OLSR packets are colliding with other packets in the air. <br>
<br>With this in mind, we experimented with changing the HelloInterval to a really short time (0.5 sec) and the HelloValidityTime correspondingly (5 sec). We had the equation HelloValidityTime = HelloInterval * LQWindowSize in mind when setting these values. We assume the LQ window size is 10. As a side note, we know that LQ
window size has been replaced by other settings, but don't know how it
has been changed or to what it has been changed to. If anyone can shed
light on that, we would appreciate it. The idea here is that if we send more packets in a shorter time, while we will still lose packets once in a while, more will get through in the long run.<br><br>Getting back to the problem, we are wondering if there are known "optimal" settings for these types of fields in the config file. We would like to overcome the fact that some OLSR packets will be dropped due to things like the hidden node problem.<br>
<br>Thanks,<br><br>Randy Buck<br>
