Usage analysis

``Statistician: A man who believes figures don't lie, but admits
that under analysis some of them won't stand up either.''

Olsrd is a daemon, or service, that constantly runs on all nodes participating in the OLSR routing domain. Therefore it is important that it does not claim more resources than necessary. On modern generic PCs, as we will see later, the amount of processing time used by olsrd is microscopic. But olsrd is also aimed at small embedded systems that in no way provide the same processing power that regular PCs does. However, in MANETs the most scarce resource is probably bandwidth. As OLSR is a pro-active protocol it generates a near to constant overhead. In this chapter we will, in addition to looking at local resource usage, take a brief look at the network resources olsrd claims.
