Security Algorithms for Mitigating Selfish and Shared Root Node Attacks in MANETs

Abstract

Mobile ad hoc network is a type of self configurable, dynamic wireless network in which all the mobile devices are connected to one another without any centralised infrastructure. Since, the network topology of MANETs changes rapidly. It is vulnerable to routing attacks than any other infrastructure based wireless and wired networks. Hence, providing security to this infrastructure-less network is a major issue. This paper investigates on the security mechanisms that are proposed for Selfish node attack, Shared root node attack and the Control packet attack in MANETs with the aid of a well known multicast routing protocol namely Multicast Ad hoc On Demand Distance Vector (MAODV). The security solutions proposed for each of the above mentioned attacks are evaluated with the help of three evaluation parameters namely packet delivery ratio, control overhead and total overhead. The algorithmic solutions thus obtained are analysed in the simulation environment by using ns-2 simulator

A Hybrid Crow Search and Gray Wolf Optimization Algorithm‐based Reliable Non‐Line‐of‐Sight Node Positioning Scheme for Vehicular Ad hoc Networks

“…In this section, the shortcomings identified from the state-of-art approaches proposed in the literature (Table 1) over the recent years [30][31] are presented.…”

Harris Hawk Optimization Algorithm‐based Effective Localization of Non‐Line‐of‐Sight Nodes for Reliable Data Dissemination in Vehicular Ad hoc Networks

“…The simulation experiments of the proposed HHOA-NLOS-LS are conducted using EstiNet 8.1 network simulator in order to investigate its predominance over the benchmarked schemes used for comparison. [27][28][29][30][31][32][33] The network simulator EstiNet 8.1 is used for simulating the proposed HHOA-NLOS-LS, since it is the world-renowned tool that is a commercial version of the NCTUns network simulator and acts as an emulator. EstiNet simulator facilitates vital capabilities that include realistic distance based vehicle movement and optimally enhanced IEEE 802.11p/1609 VANET network simulation of the road for VANET.…”

Investigating Open Issues in Swarm Intelligence for Mitigating Security Threats in MANET

“…One of the yet unanswered issues in the area of MANET is to accomplish an efficient scalability of the network. An example of the work [25] [26] [27] [28] shows that the open issue is associated with the highest dimensionality of the mobile nodes that should be considered in mobile adhoc network at the time of evaluating security issues. Reviewing Section I, it can be seen that mobile adhoc network has lack of infrastructure with less computational capability and resource constraint.…”

“…The incorporated properties of the MANET system are the sole reason for quality of services too. Although various work like [28] [29], [30], etc has addresses the routing security, but it failed to address specifically more critical issues like channel capacity (packet delivery ratio, bandwidth, jitter, delay etc). It can be easily seen from all these above mentioned work that although the optimal security is established, but it has no positive effect on QoS parameters.…”
