This Matching input keywords with historical or information domain is an important point in modern computations in order to find the best match information domain for specific input queries. Matching algorithms represents hot area of researches in computer science and artificial intelligence. In the area of text matching, it is more reliable to study semantics of the pattern and query in terms of semantic matching. This paper improves the semantic matching results between input queries and information ontology domain. The contributed algorithm is a hybrid technique that is based on matching extracted instances from booth, the queries and in information domain. The instances extraction algorithm that is presented in this paper are contributed which is based on mathematical and statistical analysis of objects with respect to each other and also with respect to marked objects. The instances that are instances from the queries and information domain are subjected to semantic matching to find the best match, match percentage, and to improve the decision making process. An application case was studied in this paper which is related to renewable energy, where the input queries represents the customer requirements input and the knowledge domain is renewable energy vendors profiles. The comparison was made with most known recent matching researches

Looking at the broad spectrum of Mobile ad hoc Networks (MANETs) applications, security challenges imposed during its deployment have triggered researchers to analyze the vulnerabilities of such networks and deduce newer reliable solutions. In this study, an attempt is made to address the challenges imposed by security impairments in Intrusion Detection Systems (IDS) in the context of MANETs. This study covers a broad analysis of IDS architectures and algorithms and measures advantages and disadvantages associated with these architectures. This study contributes significantly to IDS successful implementation and triggers researchers in this field, to develop more robust solutions encountering the security drawbacks and challenges currently experienced.

Software maintainability has been considered as a main characteristic in many software product quality models. However, these models have different definitions for maintainability and sub characteristics. ISO 9126 is one of the main and most frequently used models in software product quality. This model has been revised and replaced by ISO 25010 as a new model of software product quality. In addition to the many modifications that were performed on ISO 9126 model, maintainability was one of the main modified characteristics. However, it was developed unclearly without any standard base, and with no clear definition or evidence of how the sub characteristics were defined and modified. This paper investigates these modifications and the differences between the definitions of the maintainability in the two models, ISO 9126 and ISO 25010. As a result of this discussion, it has been concluded that both models ISO 9126 and ISO 25010 lack of a clear definition or standard base for defining software maintainability and its sub characteristics

Steganography is the techniques can be concealed secret messages inside the cover. The aim of steganography is to keep a secret message within no modified. Message integrity is the scheme that can validate the secret message when it arrived in order to ensure if it is correctly delivered or has been altered. This paper contributes to the information security community by reviewed message integrity methods that using steganography technique

Steganography is a method of hiding information inside a cover. Several algorithms were developed to hide secret messages inside digital media such as image, audio, video and text. Prior researches focused their efforts into two main issues: the security of the secret message before embedding and complexity of intelligent work to achieve a reliable message hiding inside the cover. This paper introduces a new steganography technique that addresses the security issue based on multilevel security by applied wavelet transformation and digital modulation. The secret message is being modulated inside the cover by using wavelet domain. This method will add high security to the secret message with robustness to external attackers. The experimental results have shown that the peak signal-to-noise ratio (PSNR) is near 50 db without detecting the secret message after embedded in the cover.

Multi-level encryption approaches are becoming more popular as they combine the strength of multiple basic/traditional approaches into a complex one. Many multilevel encryption approaches have been introduced for different systems, like Internet of Things, sensor networks, big data, and the web. The main obstacles in building such approaches are to have a secure as well as a computationally efficient multi-level encryption approach. In this paper, we propose a computationally efficient multi-level encryption framework that combines the strength of symmetric, the encryption algorithm AES (Advance Encryption Standard), Feistel network, Genetic Algorithm’s Crossover and Mutation techniques, and HMAC. The framework was evaluated and compared to a set of benchmark symmetric encryption algorithms, such as RC5, DES, and 3-DES. The evaluation was carried out on an identical platform and the algorithms were compared using the throughput and running time performance metrics and Avalanche effect security metric. The results show that the proposed framework can achieve the highest throughput and the lowest running time compared to the considered benchmarked symmetric encryption algorithms and passes the avalanche effect criterion.

Mobile Ad-hoc network (MANET) is the guiding technology of ubiquitous era and a cornerstone in the 4G communication architecture. MANET has limited resources and characterized with high mobility and frequent topology change. Routing in MANET should follow these constrains, otherwise, it can severely degrade the performance of MANET. Owing to Greedy routing (GFS) nature in MANET, a certain part of the MANET becomes congested before other parts. In such area the nodes have failed to forward packets in a timely manner or drop them, thus such nodes called Network Holes. This paper presents a simple and efficient enhanced GFS routing algorithm called Intelligent Fuzzy logic Greedy forwarding Scheme (IFGFS). IFGFS consider the De-congestion level of each mobile node as another selective metric besides distance. In order to validate our algorithm, we rely on a wide simulation experiments. The evaluation results showed the correctness of our new proposed algorithm the adaptive- congestion IFGFS which maximize the performance of the network.
