An Improved adhoc on demand distance vector protocol for mobile adhoc networks

Abstract

Mobile Adhoc Network is a kind of adhoc network it can change the locations and configure by itself. The Mobile Adhoc Network uses the wireless connections to connect to various networks like standard WiFi connection, cellular or satellite communication. The mobile Adhoc network does not use any static infrastructure due to multipath broadcasting and high flexibility of nodes. Because of the availability of free license in wireless communication, the use of MANET Application has been increased. MANETs Applications are implemented in disaster-management, business meetings, military operations and rescue operations. There are many different protocols are implemented in MANET while sending data packet source node to the destination node. These protocols can be classified as Proactive, Reactive and hybrid Protocols. Reactive is a very popular routing protocol used in wireless communication that provide the accessible solution for large network. Ad-hoc on Demand Distance Vector Protocol is a kind of Reactive routing protocol. There are many issues in MANET. Security issue is one of the main issue in MANET. With the aim of this research, researcher interesting to find to Detect and Prevent the Cooperative Black hole attack for AODV Protocol. Previous Authors were introduced Dynamic Learning System against Black hole attack Adhoc On Demand Distance Protocol for Mobile Ad-hoc Network. However the introduced method has only support for a single Black hole attack and its routing overhead is very high. This thesis presents the improved further implemented method Detect, Prevent and Reactive of AODV which will reduce the routing overhead and increasing the packet delivery ratio of AODV Protocol. For the implementation of the research, researcher use Network Simulator 3.24, which is new simulator written from scratch. It is supported C++ and Python language. It will depend on the ongoing contributions of the community to develop new models, debug or maintain existing ones, and share results.
