Comparative study of routing protocols in MANET

In wired networks there are different physical devices routing the traffic centrally. By consequence, we can create paths in the network by using multiple management rules, but in Ad-Hoc network nodes this work must be done in an autonomous way. For that there are three types of routing protocol proactive, reactive and hybrid. The first one continuously calculates the possible paths to be available at the time of transmission. The second one creates the roads only when they are needed. And the last one is a combination between the two methods. In this study we will focus on three routing protocols AODV, OLSR and ZRP; and compare their performance in terms of loss packets and energy efficient.
