A "mobile ad hoc network" (MANET) is an autonomous system of mobile routers (and associated hosts) connected by wireless links--the union of which form an arbitrary graph. The routers are free to move randomly and organize themselves arbitrarily; thus, the network's wireless topology may change rapidly and unpredictably. Such a network may operate in a standalone fashion, or may be connected to the larger Internet. The purpose of this presentation is to study four protocols; namely, DSDV (Distance Sequence Distance Vector), TORA (Temporally Ordered Vector Algorithm), DSR (Distance Source Routing Algorithm), and AODV-LL (Ad Hoc On Demand Distance Vector -Link Layer algorithm). A detailed packet level simulation was conducted and the four protocols are analyzed using Multi hop Wireless Ad Hoc Networks. The number of nodes that are used is 50. The wireless NS-2 simulator from Berkeley was used to model the IEEE 802.11 wireless LAN that would also include a wireless channel mode. Simulation results are presented for the following metrics: packet delivery ratio, packet delivery overhead,routing overhead as a function of pause time,number of packets sent as a function of pause time.
