Simulation And Analysis Of A Common Security Threat (Black Hole) In Wireless Ad Hoc Networks
Waseem Ahmed Hussein · 2014
AD-HOC is a temporary wireless network between mobile Nodes like laptop computers and smart phone or any device with wireless adapter, so we can call it mobile ad-hoc network (MANET), MANT is none infrastructure network based on several routing protocols, the most important protocol is AODV. AODV (Ad-hoc On-Demand Distance Vector) is an important Reactive routing protocol for mobile ad-hoc networks, Since AODV is none infrastructure network, it will be unprotected and there is no any prerequisite security against a attacks and malicious Nodes, Black Hole and Wormhole attacks are the main critical attacks against ad-hoc Nodes. In ad-hoc wireless network the expression (Black hole) refer to malicious nodes that conform the request data packet instead of destination node to routing reply message which involve the fresh routing sequence number. Immediately after the Sender Node receive the reply message from the Black hole node it will start sending data packet ,All data packet will be lost and will not reach the real destination node. The black hole nodes decrease the network performance and exhaust its neighbor's nodes resource. In this Paper, we will try to simulate data transmission over ad-hoc wireless network and the AODV Routing Table , In the same simulation we will imitate the black hole attackI
