A Survey on Rushing Attack and Its Prevention in Mobile Ad-hoc Network

Mobile Ad-hoc Network contains mobile nodes which can move freely and communicate to each other without fixed infrastructure. These nodes can be routers or hosts. MANET is an autonomous system of mobile nodes and its major characteristics include dynamic topology, limited bandwidth, energy constrained operation, limited resources and limited security. Many protocols in MANET works based on On-Demand fashion. In this paper we analyzed Rushing Attack and its Prevention. In On Demand protocols the request packets received after first packet are removed as duplicate packets. In Rushing Attack, attacker exploits this property and forwards the request packet quickly and become the part of the route. So it does not let other legitimate nodes to communicate with destination. In this paper Rushing Attack and its prevention is reviewed. Keywords— MANET, Rushing Attack, Rushing Attack Prevention
