Mobile Ad hoc NETwork (MANET) is an autonomous system of mobile nodes connected by wireless links without central infrastructure. Each node operates not only as an end system, but also as a router to forward the packets. The nodes are free to move about and organize themselves into a network and changes position frequently so that network topology unpredictably changes dynamically. Hence MANETS are best suited for the applications in which the re is not requirement for existing underlying infrastructure. In this paper, the author will provide an overview of routing protocol, traffic types, underlying issues and challenges related to security, mobility and resource limitation and also give possible solution for them.
