- MANET is one of self-configuring fastest emerging, technology, due to commencement of economical, small & more powerful wireless devices. It is being used in most of applications, ranging from military to civilian, where each node acts as router. To facilitate communication in ADHOC network, a routing protocol is vital whose primary goal is to establish accurate & efficient route between pair of nodes, due to this lot of routing protocols have been proposed for MANET & its success depends on people’s confidence in its security. In this paper we discuss an energy efficient technique of sinkhole analysis on Ad-Hoc networks.
