ABSTRACT In this paper, we propose a complete protocol to detect a chain of cooperating malicious nodes in an ad hoc network that disrupts transmission of data by feeding wrong routing information. Our technique is based on sending data in equal but small sized blocks instead of sending whole of data in one continuous stream. The flow of traffic is monitored independently at the neighborhoods of both source and destination. The results of monitoring are gathered by a backbone network of trusted nodes. With assumption that a neighborhood of any node in the ad hoc network has more trusted nodes than malicious nodes, our protocol can not only detect but also remove a chain of cooperating malicious nodes (gray/black hole) by ensuring an end-to-end checking between the transmission of two blocks of data. The protocol takes O(mdBN) time for detection and removal of gray/black holes chain which betters an earlier O(n2) time bound [4] for detecting a single black hole in the network. Here, m is the number of malicious nodes in the network, dBN is the diameter of a backbone network formed out of the flat ad hoc network, and n is the total number of nodes in the ad hoc network.

    ABSTRACT: MANETs have unique characteristics like dynamic topology, wireless radio medium, limited resources and lack of centralized administration, as a result, they are vulnerable to different types of attacks in different layers of protocol stack. Each node in a MANET is capable of acting as a router. Routing is one of the aspects having various security concerns. In this paper, we will present survey of common Denial-of-Service (DoS) attacks on network layer namely Wormhole attack, Black hole attack and Gray hole attack which are serious threats for MANETs. We will also discuss some proposed solutions to detect and prevent these attacks. As MANETs are widely used in many vital applications, lots of research work has to be done to find efficient solutions against these DoS attacks that can work for different routing protocols.

    ABSTRACT: In multi-hop wireless ad hoc networks, nodes not in direct range rely on intermediate nodes to communicate. In order to preserve its limited resources or to launch a DoS attack, an intermediate node drops packets going through it instead to forward them to its successor. In this paper, we deal with this misbehavior called black hole attack, and we propose an authenticated end-to-end acknowledgment based approach in order to check the correct forwarding of packets by intermediate nodes. Our approach detects the black hole conducted in simple or cooperative manner, the modification and the replay of messages attacks. Through simulation using OPNET simulator, we show the detection efficiency and evaluate the performance of our approach in both proactive and reactive routing based networks in terms of end-to-end delay and network load. Also, we compare the approach we propose with 2-hop ACK and the watchdog approaches in terms of detection ratio, delivery ratio and additional overhead.

    ABSTRACT: A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that forms a temporary network in decentralized manner. Security has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment of MANET which poses a number of nontrivial challenges to security design and these challenges clearly make a case of building multifence security solutions that achieve both broad protection and desirable network performance. This paper presents a review on the various network layer attacks, i.e. wormhole attack, blackhole attack and greyhole attack and existing ways to mitigate them.
