Prevention of DOS and Black Hole Attack in AODV
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Mobile Ad Hoc Network (MANET) is a self-configuring, gathering of wireless devices and infrastructure-less network technology used to create a wireless network without wire using mobile nodes. In MANET all devices are free to move independently in any direction so they change their links to other devices frequently. Its performance is based on the services of the network; however MANET’s are vulnerable to the attacks due to its dynamic topology, nomadic and open environment. However, network is vulnerable to the outside attacks by presence of malicious nodes. Therefore, MANET Networks are vulnerable because of its dynamic, nomadic and open operational environment. There are two security threats in an AODV such as DOS and Black Hole attacks. DOS attack is one of the server security scourges in an ad hoc networks aims to disrupt the services provided by network or the server by continuously sending unwanted packets using malicious node. The malicious nodes are the type of mobile nodes but it is different to normal mobile nodes as like change or removes routing information, send a fake route request to the server. The Black Hole attack captures the path and sends’s fake route reply message and routing information. So to overcome from these consequences we are proposing an algorithm which introduces a mechanism of Dos and Black Hole Attacks (BHA) prevention and check network performance in the malicious environment. Throughput and end to end delay are also analyzed.
