A Comparative Study of Routing Protocols for Mobile Ad
... In this paper, an attempt has been made to study and analyze six routing protocols (DSDV, OLSR, AODV, DSR, FSR & ZRP) and a comparison has been made between Proactive, Reactive and Hybrid protocols. It is a critical issue to select efficient and reliable protocol. FSR and ZRP are efficient in discov ...
