Abstract: Wireless networks are gaining popularity to its peak today, as the users want wireless connectivity irrespective of their geographic position. There is an increasing threat of attacks on the Mobile Ad-hoc Networks (MANET). Black hole attack is one of the security threat in which the traffic is redirected to such a node that actually does not exist in the network. MANETs must have a secure way for transmission and communication which is quite challenging and vital issue. In this paper, a brief overview is given about the black hole attack on MANETs and various kind of routing protocols which get affected by the Black Hole attack along with an overview about the countermeasures to avoid it.

Abstract: Mobile ad-hoc network (MANET) is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of Pre-established network infrastructure. These networks provide dynamically changing network connectivity owing to mobility. The mobility model represents the moving behaviour of each mobile node in the MANET that should be realistic. It acts as a crucial part in the performance evaluation of MANET. The purpose of this paper is to study the impact of mobility on the performance of Ad-Hoc On-Demand Distance Vector Routing (AODV) protocol and propose a method to analyze the optimal delay in mobile ad-hoc networks and exploit the results in NS-2 simulator.
