Identification Model

An opportunistic network is a special type of wireless mobile ad hoc network that does not require any infrastructure, does not have stable links between nodes, and relies on node encounters to complete data forwarding. The unbalanced energy consumption of ferry nodes in an opportunistic network leads to a sharp decline in network performance. Therefore, identifying the ferry node group plays an important role in improving the performance of the opportunistic network and extending its life. Existing research studies have been unable to accurately identify ferry node clusters in opportunistic networks. In order to solve this problem, the concepts of k-core and structural holes have been combined, and a new evaluation indicator, namely, ferry importance rank, has been proposed in this study for analyzing the dynamic importance of nodes in a network. Based on this, a ferry cluster identification model has been designed for accurately identifying the ferry node clusters. The results of the simulations conducted for verifying the performance of the proposed model show that the accuracy of the model to identify the ferry node clusters is 100%.

Network security is an important problem, which attracts more attention because recent network attacks caused huge consequences such as data lose, reduce network performance and increase routing load. In this article, we show network attack forms in MANET and propose Multiple Signature Authenticate (MSA) mechanism using digital signature based on asymmetric encryption RSA. Moreover, we describe a new security routing protocol named AODV-MSA by integrating MSA into AODV. Using NS2 simulator system, we implement and examine the efficiency of the AODV-MSA protocol with the 32-bit keys.

In recent years, WiFi offloading provides a potential solution for improving ad hoc network performance along with cellular network. This paper reviews the different offloading techniques that are implemented in various applications. In disaster management applications, the cellular network is not optimal for existing case studies because the lack of infrastructure. MANET Wi-Fi offloading (MWO) is one of the potential solutions for offloading cellular traffic. This word combines the cellular network with mobile ad hoc network by implementing the technique of Wi-Fi offloading. Based on the applications requirements the offloading techniques implemented into mobile-to-mobile (M-M), mobile-to-cellular (M-C), mobile-to-AP (M-AP). It serves more reliability, congestion eliminated, increasing data rate, and high network performance. The authors also identified the issue while implementing the offloading techniques in network. Finally, this paper achieved the better performance results compared to existing approaches implemented in disaster management.

A Mobile Ad-Hoc Network (MANET) is a decentralized network of mobile node that are connected to an arbitrary topology via wireless connections. The breakdown of the connecting links between adjacent nodes will probably lead to the loss of the transferred data packets. In this research, we proposed an algorithm for link prediction (LP) to enhance the link break provision of the ad hoc on-demand remote protocol (AODV). The proposed algorithm is called the AODV Link Break Prediction (AODVLBP). The AODVLBP prevents link breaks by the use of a predictive measure of the changing signal. The AODVLBP was evaluated using the network simulator version 2.35 (NS2) and compared with the AODV Link prediction (AODVLP) and the AODV routing protocols. The simulation results reveal the effectiveness of AODVLBP in improving network performance in terms of average end-to-end delay, packet delivery ratio, packet overhead ratio, and packet drop-neighbour break.

Wireless devices utilization had increased drastically, which has shown an impact on over-all demand and utilization Mobile Ad-Hoc Network (MANET). Routing protocol is the fundamental and vital performance factor in the Mobile Ad-hoc Network (MANET). The routing protocols in MANET are accomplished to handle a lot number of nodes with restricted resources. Multiple routing protocols exist in MANETs. Once of the main challenges in routing protocols is its generation of adverse influence on network performance. Accordingly, this paper plans to implement an obstacle-ware MANET routing model using improved meta-heuristic-based A* algorithm. The algorithm efficiently plots a path between multiple nodes avoiding obstacles, or points, on the graph that results in producing a shortest path without any obstacles. The improved meta-heuristic algorithm termed as Fitness and Position Ratiobased Chicken Swarm Optimization (FPR-CSO) is used to improvise the A* algorithm. The comparative analysis of different optimized A* over Ad hoc On-Demand Distance Vector (AODV) confirms the consistent performance of the proposed model

Packet Drop

Mobile ad-hoc network (MANET) is a trending field in the smart digital world; it is effectively utilized for communication sharing purposes. Besides this communication, it has numerous advances like a personal computer. However, the packet drop and low throughput ratio became serious issues. Several algorithms are implemented to increase the throughput ratio by developing multipath routing. But in some cases, the multipath routing ends in routing overhead and takes more time to transfer the data because of data load in the same path. To end this problem, this research aimed to develop a novel temporary ordered route energy migration (TOREM). Here, the migration approach balanced the data load equally and enhanced the communication channel; also, the reference node creation strategy reduced the routing overhead and packet drop ratio. Finally, the outcome of the proposed model is validated with recent existing works and earned better results by minimizing packet drop and maximizing throughput ratio.

Mobile Ad Hoc

MANET is a mobile ad-hoc network that is made of several mobile nodes that can communicate in a multi-way without any fixed or regular infrastructure. Due to its special features such as its self-organization, easy deployment it has been preferred for many military and civil applications. MANET has also gained popularity in the multimedia field. MANET has certain levels of requirements such as QoS (Quality of Service), jitter and energy, bandwidth, and end-2-end delay. MANET’s one of the basic requirements is having QoS and should have efficient routing to support other applications. In this research paper, a special Genetic Algorithm known as the GA algorithm based on routing on a Mobile Ad-hoc network is designed and termed as GAMAN. The proposed model uses a 2 QoS system for routing. The outcome of this paper showed that the GAMAN method is a significant one for QoS in MANET.

Most of routing protocols used for Mobile Ad hoc Network {MANET}, such as Ad hoc on demand distance vector {AODV} routing, uses minimum hops as the only metric for choosing a route. This decision might lead to cause some nodes become congested which will degrade the network performance. This paper proposes an improvement of AODV routing algorithm by making routing decisions depend on fuzzy cost based on the delay in conjunction with number of hops in each path. Our simulation was carried out using OMNeT++ 4.0 simulator and the evaluation results show that the proposed Fuzzy Multi-Constraint AODV routing performs better than the original AODV in terms of average end-to-end delay and packet delivery.

To improve the performance of Mobile ad hoc network (MANET), adequate time-varying interference prognoses can active adaptive design for transmission. Normally any inaccurate data transmissions are not identified initially after completion of data transmission that is detected, so lot of energy is wasted for communication. It misbehaves and affects the entire network performance. Proposed Inaccurate Packet Identification based on Pace allocation (IPPA) algorithm, if any Interference occurred that are identified by threshold value of node, node cross its threshold value, detects the attacks. Threshold value is fixed based on the battery level of all nodes process. In this work, time-varying interference can be evaluated at any period rather than considering it as long-term average effects. To enhance the network lifetime to attains mean value’s analytical results and in turn distance metric rate. The obtained simulation results authenticate the competent and accuracy of the missing data identification report and it reveals the reward of the scheme grand with the difficult Mobility. The analysis of the scheme provides better efficiency.
