Abstract :
MANET is a kind of Adhoc network with mobile, and wireless nodes. Because of its distinct features like dynamic topology, hop-by-hop communications and easy and quick setup, MANETs encountered lots of challenges allegorically routing, security and clustering. The security challenges arise due to MANET’s self configuration and self maintenance capabilities. In this paper, we present an elaborate view of issues in MANET security. Based on MANET’s special characteristics, we define three security parameters for MANET. In addition we divided MANET security into two different aspects and discussed each one in detail. A comprehensive analysis in security aspects of MANET and routing approaches is presented. In addition, defeating approaches against attacks have been evaluated in some essential metrics. After analyses and evaluations, future scope of work has been presented.
