A Mobile ad hoc network is a collection of wireless mobile nodes that are capable of communicating with each other without the use of a network infrastructure or any centralized administration. The mobile nodes perform both as a host and a router forwarding packets to other nodes. Routing in these networks is highly complex. Due to moving nodes, many protocols have been developed. Performance of each protocol is depending on their working in different conditions. This paper describes some special characteristics of ad hoc routing protocols DSR, AODV and DYMO. It also presents their performance and comparative study.
