Minimization of Routing Overhead in MANET: A Review?

Movements of nodes in a MANET cause the nodes to move in and out of range from one another. As a result, there is a continuous making and breaking of links in the network, making the network connectivity (topology) to vary dynamically with time. Routing overhead in route discovery can’t pass over. Broadcasting is important data dissemination mechanism for various network services such as route discovery, address resolution in Mobile Ad-hoc Networks (MANET). It also causes problems such as the broadcast storm problem. This paper presents review of various broadcasting techniques and how they are used for routing overhead minimization.
