Blackhole Attack in MANET - NS2 Analysis

Abstract

Mobile Ad hoc Network (MANET) is a type of wireless networks that provides numerous applications in many different areas. An ad-hoc network is an infrastructure less network, which is a collection of mobile nodes, which are arranged in a dynamic form. This network is an independent and isolated network. Security of MANET had become one of the important topics in networks fields. MANET is prone to different types of attacks,which affect its functionality and connectivity. The black-hole attack is considered one of the most widespread active attacks that degrade the performance and reliability of the network. This is dueto themalicious node, which drops all the packets received by it.
