Review Study of Routing Protocols and Versatile Challenges of MANET

MANET is collection of mobile devices form a self-creating, self-organizing and self-administering wireless networks. Or MANET is the collection of multi-hops mobiles (wireless) nodes. These are communicate with each other without any centralized control or established infrastructure. Infrastructure less environment and frequently changing topology are used. As wireless links are highly error prone and can be do down frequently due to mobility of nodes. So the stable routing is very critical task due to the infrastructure less environment in MANET. In this paper, provide an overview list of all routing protocols and also study of challenges and technology of MANET routing protocols-optimized link state routing (OLSR), destination sequence distance vector (DSDV), dynamic source routing (DSR), ad-hoc on demand distance vector routing (AODV) and temporary ordered routing protocol (TORA). Also discuss history, characteristics and applications of MANET.
