Security Challenges Related to Routing in Mobile Ad hoc Networks (MANET) and Proposed Solutions

A freely roaming nodes forming as a group of network for effective communication is called Mobile Ad hoc Networks (MANET). In MANET nodes have the liberty of moving around the network with no defensive boundaries and often nodes join and leave the network as per their need due to this nature MANET’s are insecure. In this insecure environment Routing is a critical aspect which must be done properly for secure and reliable delivery of a data and communication. In order to have a secure system we need design a system which provides security to the mechanism of routing i.e. Route Discovery in a efficient way, Route maintenance with less cost and there should be secure Packet forwarding/delivery. In this paper we are trying to study the mechanism of routing as well as various attacks on functionality of routing. We are also studying different solutions to the various attacks on the routing mechanism of MANET and try to propose a best solution
