Performance Comparison of Routing Attacks in Manet and WSN

Routing is a basic step for data exchange. In wireless ad-hoc networks each node acts as a router and executes a routing protocol. Wireless ad-hoc networks are highly resource constrained in terms of network topology, memory and computation power. The reliable data transfer is a difficult task in wireless ad-hoc networks because of resource constraints. A mobile ad-hoc network (MANET) is a kind of wireless ad-hoc network, and is a self-configuring network of mobile routers connected by wireless links. A wireless sensor network (WSN) is a highly constrained wireless ad-hoc network. In these network, multicast is the efficient routing service for data broadcasting. Denial of service (DOS) attack, sinkhole, wormhole, sybil, black hole and rushing attacks are some routing attacks. So, it is necessary to study the impact of routing attacks on existing multicast routing protocols to suggest a suitable secure multicast routing protocol. The objective of this paper is to study the effects of black hole and rushing attack on MANET and WSN. The NS-2 based simulation is used in analyzing the black hole and rushing attacks. From performance metrics such as packet delivery ratio (PDR), packet drop ratio (PDrR), network throughput (NTh) and energy consumption it is observed that the routing attacks have severe impact on MANET than WSN.
