Mobile Ad-hoc NETwork (MANET) is wireless networks in which the nodes are free to move arbitrarily (i.e.,) it does not need any infrastructure support. As the nodes are not fixed, biggest problem about routing among nodes. As large numbers of MANET protocols are there but no single protocol is used in all conditions. This paper gives an overview of such routing protocols by representing there functionality and characteristics along with merits and demerits. Some of the recent activity about MANET has discussed.
