Trust-based secure routing against lethal behavior of nodes in wireless adhoc network

Offering a secure communication in wireless adhoc network is yet an open-end problem irrespective of archives of existing literatures towards security enhancement. Inclination towards solving specific forms of attack in adhoc network is majorly seen as an existing trend which lowers the applicability of existing security solution while application environment or attack scenario is changed. Therefore, the proposed system implements an analytical secure routing modeling which performs consistent monitoring of the malicious behaviour of its neighboring node and formulates decision towards secure routing by the source nodes. Harnessing the potential ofconceptual probabilistic modeling, the proposed system is capable as well as applicable for resisting maximum number / types of threats in wireless network. The study outcome show proposed scheme offer better performance in contrast to existing secure routing scheme

A novel secure routing scheme using probabilistic modelling for better resistivity against lethal attacks

Study towards Wireless Adhoc Network dates two decades back with various researchers evolving up with new solutions towards addressing its problems. Irrespective of various other problems, the issues related to the secure routing is yet unsolved owing to massively increasing fatal strategies of the adversary. Review of existing literature shows that the existing secure routing scheme can only govern over the stated attacks reducing the applicability in case of dynamic attacks. Therefore, this manuscript introduces a novel probabilistic model which offers the capability to wireless nodes to identify the malicious behavior and react accordingly. Different from existing intrusion prevention system, the proposed system allows the malicious node to participate in the data forwarding process and exhaust its resources with no chance of launching an attack. The simulated outcome of the study shows that the proposed secure routing scheme offers better data forwarding characteristic in contrast to the existing system in the aspect of intrusion detection and secure data transmission

Avoiding and Isolating Flooding Attack by Enhancing AODV MANET Protocol (AIF_AODV)

Security in MANET is an essential task in preventing the harm that could be caused by malicious nodes in the network. Flooding attack is one of DoS attacks that aim to exhaust the network resources by flooding the network with a lot of fake packets and messages. There are different forms of Flooding attacks, and the most common form is the request one. Request Flooding attack keeps flooding the network with a lot of requests to the fake nodes that do not exist in the network. In this research, we presented a new enhanced AODV protocol AIF AODV that can detect and isolate flooding nodes in the network. NS-2.35 is used to simulate and to prove the efficiency of the proposed technique. The results of the enhanced protocol in terms of Throughput, End to End Delay, PDF, ARE, and NRL are very close to the native AODV without Flooding attack. The comparisons with other models showed that the proposed model AIF_AODV has a better Throughput characteristic
