So, the effectiveness of FANET is reduced by enhancing the packet transmission expenses due uncreative and indecisive communication among UAVs in multidimensional environment. The optimal path selection will support to pro cient message transmission and offer energy competent and protected communication above FANET. Thus, an Improved Honey Badger Optimization based Communication Approach (IHBO_CA) is implemented for optimal path selection among UAVs above FANET. The sinusoidal chaotic map is combined with honey badger algorithm to improve the performance of optimized communication. The IHBO_CA is implemented using MATLAB 2021a platform and outcomes demonstrate the greater effectiveness of IHBO_CA against OLSR, MP-OLSR, ACO, PSO and HBA depending on energy expenditure, overhead, time complexity, packet delivery ratio and delay.

Routing is indeed a big problem with MANET because of features such as transitory architecture as well as the lack of centralized authority. A novel multi-way routing technique is proposed in this work using a simulated annealing methodology. In such a competitive dynamic actual network setting, the recommended metaheuristic strategy can obtain bigger and more reciprocating benefits. As a result, the proposed routing technique is an excellent way for resolving the conflicting MANET routing challenge. The proposed methodology responds best to the fluctuation of different network circumstances, according to simulations. The overall energy level, available bandwidth, packet drop frequency, and traffic loading are all increased with the proposed methodology when compared and evaluated over the present systems.

Spreading this kind of data undermines societal cohesiveness and well by cultivating political division and doubt in government. Since of the sheer volume of news being disseminated through social media, human confirmation has ended up incomprehensible, driving to the improvement and arrangement of robotized strategies for the recognizable proof of wrong news. Fake news publishers use a variety of stylistic techniques to boost the popularity of their works, one of which is to arouse the readers’ emotions. Due to this, text analytics’ sentiment analysis, which determines the polarity and intensity of feelings conveyed in a text, is now being utilized in false news detection methods, as either the system’s foundation or as a supplementary component. This assessment analyzes the full explanation of false news identification. The study also emphasizes char...

Twitter plays an important role on sharing user's opinion on a variety of topics, wo mining these twitter data is a very difficult task because its unstructured nature. Location plays an important role in finding opinions towards any topic because the opinions of users may vary from location to location so its very important to find opinion based on location which give in-depth knowledge where the topic is highly accepted or rejected. Opinion Mining deals with opinions or emotions of subjective elements in the textual documents. In this paper, we can take twitter data because on twitter a huge opinions are shared. In these, we can fetching a realtime data from Twitter by using flume and store these data into HDFS which is a storage component of Hadoop. Hadoop is an best open source solution for storing and processing a large amount of data. We can integrate Apache pig and hive with Hadoop and analyze the opinion on the basis of location because opinions are changes from location to location.

Cloud computing provides the ability to utilize scalable, distributed environment via internet on demand and pay as per use. Today’s cloud computing place centralized, universal trust in all the cloud nodes. However there may be negative impact on the nodes that are compromised and leads to various attacks. To address these issues, a number of research papers have been presented by authors. In this paper are given a review of these papers. More precisely are try to find out the limitation of existing technique and try to overcome them.

Cluster-based routing is a solution to limit the amount of routing information that propagates inside the network. Clustering is a technique to group the network nodes into a number of overlapping clusters. During the cluster formation phase, the ordinary nodes select best from dominating nodes as the clusterhead. Dominating nodes are potential nodes to become Clusterheads. The mobile nodes are vulnerable to security attacks, so ensuring the security of the network is essential. To enhance security, it is important to evaluate the trustworthiness of nodes without depending on central authorities. The proposed work calculates trustworthiness of the nodes based on all previous transactions and takes it in to account while electing Clusterheads.

Drones have high mobility in 3D (3 dimensional) environment and low battery power, which produce various problems such as small journey time and infertile routing. The optimal routing for communication will assist to resolve these problems and provide the energy efficient and secure data transmission over FANET. Hence, in this paper, we proposed a whale optimization algorithm based optimized link state routing (WOA-OLSR) over FANET to provide optimal routing for energy efficient and secure FANET. The efficiency of OLSR is enhanced by using WOA and evaluated performance shows the better efficiency of WOA-OLSR in terms of some parameters such as a packet delivery ratio, end to end delay, energy utilization, throughput, and time complexity against the previous approaches OLSR, MP-OLSR, P-OLSR, ML-OLSR-FIFO and ML-OLSR-PMS.

It is used to classify the content of the text into neutral, negative and positive classes. Various researchers have used different methods to train and classify twitter dataset with different results. Particularly when time is taken as constraint in some applications like airline and sales, the algorithm plays a major role. In this paper an optimization based machine learning algorithm is proposed to classify the twitter data. The process was done in three stages. In the first stage data is collected and preprocessed, in the second stage the data is optimized by extracting necessary features and in the third stage the updated training set is classified into different classes by applying different machine learning algorithms. Each algorithm gives different results. It is observed that the proposed method i.e., sequential minimal optimization with decision tree gives good accuracy of 89.47% compared to other machine learning algorithms.

Cloud can deliver resources and services to computers and devices through internet. Since Cloud Computing involves outsourcing of sensitive data and critical information the security aspects of cloud need to be dealt carefully. Strong authentication, focusing mainly on user-authentication, acts as a pre-requisite for access control in the cloud environment. In this paper we discuss an efficient authentication mechanism to deal with the security threats that are faced by cloud. The method proposed in this paper prevents the confidential data and information of end users stored in a private cloud from unauthorized access by using a two-factor authentication involving shared image concept in addition with encrypted key authentication.MD5 hashing technique is used which takes binary pixel value of image as input and conver...
