Study of On Demand Adhoc Routing Protocols

Abstract— Efficient routing is one of the key issues in the design of adhoc network systems. There are number of protocols available for the routing purpose in MANETs under various categories. This paper provides an idea of working of three on demand routing protocols viz AODV, DSR and TORA with their merits and demerits. These protocols have been compared considering various performance metrics. An analysis of these protocols has been done in NS-2 for packet delivery ratio and routing overheads. This paper paves the path for the judicious selection of an on demand routing scheme for a given network scenario.
