Hardware assisted misbehaving nodes detection in mobile ad hoc networks

The mobility feature leads to the proliferation of wireless networks. Among all kindsof wireless networks, the peer-to-peer nature of Mobile Ad hoc Networks (MANET)makes such networks very promising. Unlike traditional wired networks, MANETs donot need infrastructure to work properly. The most commonly used routing protocols formobile ad hoc networks do not take into consideration security, assuming all the mobilenodes will coordinate with each other. Such routing protocols along with the absence ofinfrastructure make MANETs prone to a variety of faults such as packet dropping, packetmisrouting, etc.This dissertation addresses the security issues of MANET by presenting the hardwareassisted misbehaving nodes detection. In such a scheme, the hardware is responsible fordetecting the misbehaving nodes. The detection results are sent to software layer ofmobile nodes. Upon receiving the detection results, the software layer can exclude themisbehaving nodes from the networks.This dissertation presents two hardware detection schemes. Two-timer is a low-costdetection scheme. There are only two timers utilized in the scheme. The two-timerscheme can be used to detect simple packet dropping with good detection performance.The other detection scheme, cache scheme, can detect both packet dropping and packetmisrouting. The cache scheme needs more resource than the two-timer scheme alongwith better detection performance

A Comprehensive Survey on Routing and Security in Mobile Wireless Sensor Networks

With the continuous advances in mobile wirelesssensor networks (MWSNs), the research community hasresponded to the challenges and constraints in the design of thesenetworks by proposing efficient routing protocols that focus onparticular performance metrics such as residual energy utilization,mobility, topology, scalability, localization, data collection routing,Quality of Service (QoS), etc. In addition, the introduction ofmobility in WSN has brought new challenges for the routing,stability, security, and reliability of WSNs. Therefore, in thisarticle, we present a comprehensive and meticulous investigationin the routing protocols and security challenges in the theory ofMWSNs which was developed in recent years

A COMPREHENSIVE SURVEY ON DETECTING BLACK HOLE ATTACK IN MOBILE AD-HOC NETWORK (MANET)

The infrastructure-less nature and mobility of nodes in mobile ad-hoc network (MANET) make it to be very susceptible to various attacks. Besides, owing to its flexibility and simplicity, there is no predefined time or permission set for nodes to leave or join the network and each node can act as a client or server.  Nevertheless, securing communication between nodes has become a challenging problem than in other types of network. Attacks in MANET range into different categories. Black hole attack is one of the attacks that has been addressed by many researchers in the recent years. It does occur when a harmful mobile node called black hole becomes a part of the network and tries to use its malicious behaviors by sending fake route reply packets (RREP) for any received route request packets (RREQ). When these faked packets arrive to the source node, it does reply to them by sending data packet via the established route. Once the packets are received by the black hole, it drops them before reaching the destination.  Hence, preventing the source node from reaching the intended destination. In this paper, we present an overview of a wide range of techniques suggested in the literature for detecting and preventing black hole attacks in mobile ad hoc network. Additionally, the effect of each approach on the network performance is also presented

A Survey on Intrusion Detection System in MANET

A mobile ad hoc network is an infrastructure less network which is prone to various malicious attacks when incorporated in applications. It is a dreadful task for attaining security to the greatest degree in MANET. This is awaited to the diverse characteristics of mobile ad hoc networks which unlike from well-established infrastructure network. In order to overcome this security challenges the Intrusion detection systems have been deployed in the ad hoc network. In this paper we focus on surveying heterogeneous intrusion detection systems used in MANET for defending various attacks

Literature Survey of Security Enhancement in MANET Routing Protocols of WLANs

A Mobile Ad-hoc Network (MANET) is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. One of the main issues in such networks is performance- in a dynamically changing topology; the nodes are expected to be power-aware due to the bandwidth constrained network. Another issue in such networks is security - since every node participates in the operation of the network equally, Malicious nodes are difficult to detect. There are several applications of mobile ad hoc networks such as disaster recovery operations, battle field communications, etc. The most active research area under MANET routing protocol is security. MANETs have certain unique characteristics that make them vulnerable to several types of attacks. Since they are deployed an open environment where all nodes co-operate in forwarding the packets in the network, Malicious nodes are difficult to detect
