Being a proactive protocol, OLSR uses power and network resources in order to propagate data about possibly unused routes. While this is not a problem for wired access points, and laptops, it makes OLSR unsuitable for sensor networks that try to sleep most of the time.

For small scale wired access points with low [[Central processing unit|CPU]] power, the open source [http://www.olsr.org OLSRd] project showed that large scale mesh networks can run with OLSRd on thousands of nodes with very little CPU power on {{val|200|ul=MHz}} embedded devices. {{Citation needed|reason=We need a source for "large scale mesh networks ..." and "very little CPU power" |date=June 2019}}

Being a link-state protocol, OLSR requires a reasonably large amount of [[Bandwidth (computing)|bandwidth]] and CPU power to compute optimal paths in the network. In the typical networks where OLSR is used (which rarely exceed a few hundreds of nodes), this does not appear to be a problem.
