Implementation and performances of the protocols of routing AODV and OLSR in the Ad hoc networks

Ad-hoc mobile networks consist of many mobile nodes which communicate by wireless connections without any fixed infrastructure. Our present article, we will compare two types of routing: the reactive algorithm (AODV) and the proactive algorithm (OLSR). Through our simulation carried out under NS2 (Network Simulator 2), we will show a classification of the various algorithms of routing studied according to the metric ones such as the number of packages sent, received or lost, and also the time of selection of road according to flow. The result of our simulation will show that protocol AODV is effective for a suitable use of the band-width.
