A Survey on Different Types of Techniques Used Against Wormhole Attack in MANET
V. Deepika, K John Singh · 2015
A Mobile Ad hoc Network (MANET) is an infrastructure less network that includes of the mobile nodes which are independent of each other and connected through a wireless network. This type of network always faces the security threats. Networks have different types of attacks, in that wormhole attack is one of the well-known and noticeable attacks. These type of attack lets the malicious node to pretend like it's an actual node in the network and acts like it is the nearest node to the source node. And also it is capable of dropping the packets sent by the source node to the destination node. Earlier many approaches were proposed in order to avoid and reduce the wormhole attack. In order to provide an efficient method to overcome this problem, an efficient method is proposed which is capable of reducing the packet loss and assures the security. This proposed method is used along with the AODV (Ad hoc On demand Distance Vector) routing protocol which is capable of reducing packet loss and delay.
