A Mobile Ad hoc NETwork (MANET) is self-organizing, dynamic topology network, which is formed by a collection of mobile nodes through radio links. MANETs enable wireless communication between mobile devices without relying on a fixed infrastructure. Hence, routing in dynamic network is a new challenge. The authors used various routing algorithms for smooth exchange of information between mobile nodes. Generally, they imply security on all the nodes of the network. But this causes wastage of time and cost. This paper proposes that first they have to find out the shortest path and then imply the security in multicast routing.
