Secure Routing in Mobile Ad hoc Network

Abstract— MANET is a wireless Mobile ad-hoc network which includes mobile nodes. In MANET mobile refers to the movable nodes which can change their location frequently. MANET is a network which has no central infrastructure; it is a self-managing and self-configuring network. In MANET devices can be heterogeneous like laptops, mobiles, PDAs etc. Due to the movement of the nodes and no infrastructure MANET can be used in disaster and emergency situations. MANET has the characteristics of dynamic topology, multi hop routing, energy constraint and easy setup. The nodes in the MANET work as a both host and a router, to make routes in the network. Due to all these flexible features of MANET there are many security vulnerabilities arises. In MANET routing is a main concern due to the mobility and the node work as a router. The security of the routing layer is essential because if any attack interrupts the communication then security of whole network can be compromised. There are different types of attacks in MANET: such as internal attacks, external attacks and other attacks of all layers. Network layer attacks are identified in this paper. Some routing protocols are used for the security of routing in MANET like SAODV, SRP, SEAD and Ariadne etc. In this paper we present a review of routing attacks and their possible solutions how to avoid from these attacks.
