PERFORMANCE EVALUATION OF PACKET DROPS IN WIRELESS INFRASTRUCTURE LESS NETWORKS

Abstract

MANETs system made out of remote portable device that communicates by transferring on wireless
medium. This system & portrayed by absence of infrastructure, without focal facilitator and central assets.
Communication is conceivable by device in a system are helpful; however it is not generally valid in disseminated
compelled asset condition. Hacker can play out the malicious exercises by not following directing convention of
network layer protocols, one such attack is black hole attack. In which black hole device control the routing
messages and pull in the correspondence data towards it and after that drop the data. Earlier works identifies and
prevent black hole attack by observing the nodes in a network, which is not practical arrangement in hostile
environment. The proposed technique mitigates Black hole Attack from routing path in MANETs by Secret Key and
Hashing. Analysis of our results demonstrates that our proposed technique precisely remove the black hole attack
and extend the performance of network
