Mobile Ad hoc NET work (MANET) is a self configuring network of mobile routers (and associated hosts) connected by wireless links – the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the wireless network topology may change rapidly and unpredictably. Such a network may operate in larger Internet. There are various routing protocols available for MANETs. The most popular ones are DSR, AODV and DSDV. This paper examines two routing protocols for mobile ad hoc networks– the Destination Sequenced Distance Vector (DSDV), the table- driven protocol and the Ad hoc On- Demand Distance Vector routing (AODV), evaluates both protocols based on packet delivery ratio and average delay while varying number of sources and pause time.
