A Survey on Various Routing Protocols in Manet with Various Protection Schemes

Abstract

A MANET is a dynamic collection of the wireless mobile devices that can communicate and move at the same time. The demand of MANET is increasing due to its application in the various fields such as the military and commercial operations, sensor networking, flood affected areas etc. This is so, as the MANET nodes can communicate through wireless links and transfer the data packets from one point to another. But, the main challenge in MANET is to design the robust security solution that may protect the MANET from various routing attacks. Without any centralized administration, these mobile nodes are placed at different ranges in a particular defined area. Flooding attack is kind of the security threat in which source node sends huge amount of data, Root Request (RREQ) and Sync packet to destination node, due to which the receiver shall not work properly as it would be engaged in receiving the excessive amount of data, RREQ and Sync packets from the attacker. To attain the optimal improved results, various routing protocols are implemented and used. In this paper we shall discuss various attacks such as Black Hole, Gray Hole attack & various prevention schemes like OSPF, RIP, IGRP, and EIGRP to protect it from the attack.
