The Mobile Ad-hoc NETwork (MANET) is a collection of self-configuring mobile node without any infrastructure. The mobile nodes with wireless radio interface are connected by wireless links where each device in a MANET is free to move independently and randomly with the capability of changing its links to other devices frequently. It is a multi-hop process because of the limited transmission range of energy constrained mobile nodes and thus each device in network topology acts as a router. Many protocols are reported in this field but it is difficult to decide which one is efficiently best. In this paper on demand routing protocols AODV, DSR and DYMO based on IEEE 802.11 are examined and characteristic summary of these routing protocols is presented.
