Routing Protocols

Asked by Sebastian on 2009-04-16

Hello,

are there any mesh networking routing protocols (like DSR, AODV, OLSR, ..) available yet? If not, do you plan to implement some of them shortly?

Kind regards, Sebastian

Hi Sebastian,

One year ago I implemented AODV under tinyOS. If such an implementation
does not yet exists I would be eager to do it.

With kind regards,

Leszek

Hi Leszek,

thanks for answering. I'd need OLSR and some directional routing protocol. If it's not there already I'll start implementing OLSR middle of May. Since I'm brandnew (and clueless) in the openWNS: if there's already a working implementation of whatever routing protocol, that would clearly be beneficial.

Did you already have in mind implementing AODV?

Greets, Sebastian

Hi Sebastian,

So far, there is no implementation of a routing protocol in the openWNS, and here at ComNets Aachen we are (currently) not working on any implementation.

However, there is already
* an implementation of the link metric measurement (using the beacons between MPs and APs to measure SINR, and then map it to a metric similar to the "AirTime" defined by IEEE 802.11s).
* an implementation of the forwarding FU, which assumes an existing path selection protocol
* an interface class for the path selection protocol
* an implementation of the interface with "perfect" path selection protocol, which uses a simulator-wide "blackboard" where the nodes can exchange their link measurement without transmission costs.

Hence, what is missing is another implementation of the interface class using the protocol that you would like to simulate. In my view, the best way to start is to look at the different classes in the wifimac/src/pathselection directory.

BR,
Sebastian
