“…Also it empowers individual nodes to maintain global flow state which in turn enables them to both setup and enforce bandwidth limits in a distributed fashion. S.Venkatasubramanian and N.P.Gopalan [10] have proposed a distributed defense technique to mitigate the DoS attacks. The technique for monitoring the node selection is designed that detects all affected packets while selecting the monitoring nodes so as to cover the entire network.…”

In mobile ad hoc networks (MANETs), the malicious flooding attack is very hazardous since it not only clogs the victim node but also the entire network. Also it may cause packet drops or alteration of the routing message that will further result in network dysfunctioning. In this paper, we propose a swarm based detection and defense technique for malicious attacks in mobile ad hoc networks (MANET). In this technique, the nodes with highest trust value, residual bandwidth and residual energy are selected as active nodes using swarm intelligence based ant colony optimization. Each active node monitors its neighbour nodes and estimates the trust value. If the active node finds any node below a minimum trust threshold, then the node is marked as malicious and an alert message is sent to the source node. When the source node wants to forward the data packet to destination, it discards the malicious nodes in that path and bypasses the data through other nodes in alternate path. It also performs the certificate revocation process for the malicious nodes. By simulation results, we show that the proposed approach reduces overhead.

“…Through the deep research, extensive usage of the MANET and Wireless Sensor Network (WSN) [4], opportunistic networks deny routing model in the traditional network, and improve the stability of path. Although Epidemic routing protocol [5], Spray and Wait routing protocol [6] that are based on encoding routing protocol can reduce TTL, they can cause much network overhead and ignore to improve QoS [7]. Probabilistic Routing Protocol using History of Encounters and Transitivity (PROPHET) is a kind of probabilistic routing protocol, which can transmit messages by encountering probability of nodes.…”

Opportunistic networks are similar to the mobile ad hoc networks (MANETs) that does not have fixed infrastructure, and the messages can be transmitted by nodes in a "store - carry - forward" approach. The mobile nodes randomly move, which result in a constantly changed network topology and frequently interrupted link. Thus, multipath routing has been proposed to improve the stability of link, extend path lifetime and reduce packet loss rate. The paper first analyzes the traditional multipath routing protocol and its path selection theory, and then investigates quality of service (QoS) metric to improve transmission efficiency of opportunistic networks, and finally proposes a reliable node based on multipath QoS routing protocol, named as RNMR. In RNMR, the stable path contains primary path and two backup paths. The primary path consists of reliable nodes and intermediate nodes, and the two backup paths are formed by two disjoint sub-paths selected from two adjacent and reliable nodes. By comparing with the backup source routing (BSR) protocol and greed-based routing (GBR-WB) protocol, the paper proves RNMR protocol has longer path lifetime, deliver rate and relay are also improved.

“…As the packet drop increases, it also affects the packet delivery ratio, routing load and throughput etc [10,12]. Packet flow is monitored and when packet drops increases, it causes a frequent change in sequence number and when it crosses a threshold limit, then alarm is raised and finally malicious nodes are removed from network on the basis of losses caused by them [11,14]. One of the major reasons to address the security aspects in MANETS is the usage of wireless transmission medium, which is highly susceptible or vulnerable to attacks.…”

The wireless adhoc networks are highly vulnerable to distributed denial of service (DDoS) attacks because of its unique characteristics such as open network architecture and shared wireless medium. A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its legitimate users. The denial of service (DOS) does not result in information theft or any kind of information loss but can be very dangerous, as it can cost the person a large amount of time and money. Significant efforts have been made towards making adhoc network secure and free from DDoS attacks. In this paper we study how various detection parameters together work as a single and efficient method to detect various DDoS attacks in Manet. Later in this paper a technique to prevent DDoS attacks in Manet is also presented which help in preventing the attacks to communicate in the network and did not allow them in the network.
