Hi, <br><br>I'm writing this because I am interested in understanding why mesh routing protocols send unreliable/unacknowledged TC updates. Modern day wired routing protocols such as OSPF and EIGRP both use reliable updates. As OLSR is designed for unreliable wireless networks it therefore seems a little strange that we have moved to unreliable updates.<br>
<br>It seems that the number one problem for link state routing is having the LS databases desynchronised. I have read that OLSR compensates for its unreliability by sending redundant TC messages. If we could send acknowledgements reliably then surely we could reduce the number of TC messages that need to be sent. This would mean that the increased overhead of acknowledgements, used to provide reliable TC messages, would not be as great as they may initially appear. <br>
<br>I read on the wikipedia page for OLSR that using reliable updates in wireless mesh networks is much more difficult to implement than in traditional protocols. Is this the main reason? Why is this?<br><br>Thanks for your time<br>
