Abstract

-A mobile ad-hoc network (MANET) is a self- configuring infrastructure less network of mobile devices connected by wireless. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network. In this paper we have done comparative analysis of various topology based routing protocols and laid more emphasis on LAR-1 LAR 2 routing protocols. We have also introduced AODV+PGB, a broadcasting mechanism and is aimed at reducing broadcast overhead.
