Mobile ad hoc network is composed of wire free nodes that are moving in nature and they are configured to form a self-configured infrastructure less network So, the energy consumed by every node is varied due to the movement of the nodes Open Shortest Path First is the shortest path estimating routing scheme which is created more energy and more delay for data transmission when the link fails in the network To overcome this difficulty, this paper proposed an efficient innovative hello based path recovery (HBPR) routing protocol for the shortest path calculation During transmission, if the link fails in the network layer then the HBPR scheme creates the alternate path, thus it reduced the delay time and energy consumption Subsequently, the novel simplified honey pot optimization (SHPO) is introduced to predict the harmful nodes within the network This SHPO maintains the path stability and node security of the network also it will improve the quality of service parameters The implementation of this research is done by MATLAB R2018b and the simulation results illustrate the performance of the proposed algorithm This approach achieves better results in packet delivery ratio, delay, average energy consumption, and throughput compared to other existing approaches

Prediction of Node and Link Failures in Mobile Ad Hoc Network Using Hello Based Path Recovery Routing Protocol

Mobile Ad hoc Network is self-organized and movable in nature, it is widely used in various applications including military and private sectors. However, security is one of the key concerns in routing because of the moving nodes; thus it is usually affected by Black Hole and Grey Hole attack. These types of malicious activities are more harmful to the network channel, and once the attack is happened it is difficult to predict and mitigate. To end this problem the current research proposed a novel Grey Wolf Trust Accumulation (GWTA) Schema in wireless mesh network architecture, thus the attacks are identified by the finest function of the GWTA model. Moreover, the predicted attacked nodes are replaced to the last position of the network medium to prevent the packet loss. Furthermore, the comparison studies proved the effectiveness of the proposed model by attaining less packet drop and high throughput ratio rate.

A Novel Wolf Based Trust Accumulation Approach for Preventing the Malicious Activities in Mobile Ad Hoc Network

Abstract Military tactical networks (MTNs) have grown in size and complexity as the volume of battlefield communications business has increased dramatically. There is a critical need for a quantitative evaluation method to assess the performance of MTNs. Based on the transmission characters of battlefield communication business and the availability of communication equipment, this paper proposed a Markov chain-based network steady-state availability model. Using this model and the analysis of the CSMA/CA transmission protocol as preconditions, a delay-based quantitative evaluation model of network business availability is proposed based on statistical principles. The relationship between network business availability and crucial metrics such as node size and node failure/repair ratio is investigated in simulation experiments to ensure the validity and correctness of the proposed model. The work done in this paper contributes to effectively evaluating the overall availability of MTNs in a complex environment.

In recent times WiFi Direct is a technology that can enable direct-to-direct device communication, single-group communication, or multi-group communication with each other device without any access point or without any internet access point. This paper expresses the WiFi Direct based multi-mode selection mobile ad hoc network. Basically here is a gateway layer and routing layer developed for supporting single group communication or multi-group communication between each WiFi direct supported device. This paper describes how to optimize the redundancy, how to select random group owners through WiFi Direct, and how to give priority to messages and among nodes also. Priority nodes have been selected from random nodes.

Mobile Ad hoc Network (MANET) is a frameless, wireless network with no central access point. The network consists of migrant nodes. Topology is highly dynamic, unpredictable, and its probability of link failure is high due to continuous mobility of the nodes. As a result, we find that the nodes are no longer reachable and it moves away from the mobile or active path. This maximizes the dropping estimate, end-to-end delay and also undergoes cut in packet delivery rate thereby leading to degradation of network efficiency. In order to conquer such consequences, our work proposes designing of a route repairing mechanism in MANET. The basic idea of our proposed routing protocol is to find an optimal path based on the minimum hop count in the multipath scenario. Based on the widespread simulation of the proposed mechanism, done by adopting NS2 and by relative study of the same with existing protocol AODV, it was found that the projected routing mechanism helps in enhancing the performance and brings about improvement in ratio of packet delivery, packet loss as well as end-to-end delay.
