Survey on Location Based Routing Protocols in MANET

Abstract- Due to the infrastructure less and dynamic nature of mobile ad hoc networks it becomes challenging to establish and maintain a connection between two end points. Therefore designing a routing protocol for MANET is now became a broad area of research. While establishing and maintaining a end to end connection or route in a MANET many routing parameters like routing overhead, end to end delay, packet delivery fraction can get affected. So the routing protocols are designed in such a way that optimizing these parameters. In routing protocols like AODV, DSR etc. routing overhead is a big concern as route request floods in all direction in these protocols. In location based routing, the nodes location information is used to route the packets. In LAR the route request is forwarded in the direction of destination node. This selective flooding reduces the routing overhead in the network. This paper gives the study and comparison of some location based routing protocols
