CCF can destabilise economies, reduce confidence between customers and banks, and severely affect other people and businesses. The primary objective of banks and businesses is to identify fraudulent transactions with a high level of accuracy. Also, reduce false alerts and the costs of manual investigation activities. When identifying CCF in large d...

With the growth of online shopping, Credit Card Fraud (CCF) comes out as a serious menace. For this end, the automatic and real-time fraud detection field calls for several studies. The recent ones use many Machine Learning (ML) methods and techniques due to their beneficial characteristics to build a good fitting model to catch fraudulent transact...

In the evolution process of humans, nature has played an important role in the transformation of mathematical investigation knowledge to modern human technological advancement. Nature optimizes the work based on biological, physical and chemical principles integrated with numerous mathematical models. People have learned the different principle and...

Functional link artificial neural networks (FLANNs) are sensitive to weights’ initialization and adopted learning algorithms. Using an efficient learning algorithm and randomly initialized weights leads to improve FLANNs efficiency and performance. The performance of the TLBO-FLANN model was proved in literature through simulation study and compari...

Nowadays, wireless networks have become a far-reaching part in contemporary life. They allow people to be connected to the Internet anytime and anywhere. And yet, the continual enhancement and/or updating of the Quality of Service (QoS)/Quality of Experience (QoE) on such platforms, notably for sensitive transmission, remains a particularly challen...

Video streaming over Mobile Ad-hoc Networks (MANETs) has been on the fore as one of the most chiefly solicited web services. Within this context, the enhancement of the Quality of Experience (QoE) on such platforms, whose signature characteristic is the real-time fluctuation of their Mobile Nodes (MNs), remains a high-stakes challenge for high-fide...

The performance of a Mobile Ad hoc Network (MANET) is closely related to the capability of routing protocols to adapt themselves to unpredictable changes of topology network and link status. In simulations, performance studies of routing protocols depend on the chosen mobility model. Consequently, the comparison of the obtained performance results...

In this paper, we address the problem of cell association during a handover performed in a dense heterogeneous network, where the preference of a mobile user’s equipment in terms of uplink traffic is not the same as for the downlink traffic. Therefore, since mobility is an intrinsic element of cellular networks, designing a handover from the perspe...

The unexpected change in user equipment (UE) velocity is recognized as the primary explanation for poor handover quality. In order to resolve this issue, while limiting ping-pong (PP) events we carefully and dynamically optimized handover parameters for each UE unit according to its velocity and the coverage area of the access point (AP). In order...

We consider the user equipment (UE) velocity as a vital trend in association problem in heterogeneous networks (HetNets), since there is a considerable relation between the velocity and the handover failure (HOF) as well as the probability of unnecessary handovers (ping-pong (PP) events). Several works have been carried out, in the context of stand...

The main contribution of this paper is the modeling and implementation of an automatic facial expression analysis system for measuring emotional customer that can predict their behavior in the decision-making. The model is based on POEM algorithm to extract face features and detect customer emotions. Then, we classify those emotions by SVM classifi...

The concept of heterogeneous networks has already begun with the 4G that will allow communications using all types of services based on IP, and perform a soft handoff between heterogeneous networks. Decisions for vertical handoff in heterogeneous, affect the QoS of the mobile users, which are also dependent upon the mobility. Consequently the choic...

One of the biggest challenges of Next-generation wireless network (4G) is to integrate different wireless access technologies, each with its own characteristics, into a common IP-based core network to provide mobile user with service continuity and seamless roaming. Nowadays there are different wireless access technologies allowing users to stay “a...

Mobile Ad hoc NETworks (MANETs), characterized by the free move of mobile nodes are more vulnerable to the trivial Denial-of-Service (DoS) attacks such as replay attacks. A replay attacker performs this attack at anytime and anywhere in the network by interception and retransmission of the valid signed messages. Consequently, the MANET performance...

Mobile Ad hoc NETworks (MANETs), like traditional networks, are vulnerable to a wide range of Denial-of-Service (DoS) attacks. A Replay attack is one of them that degrade severely the MANET performance. A replay attacker performs this attack by interception and retransmission of the valid signed messages. The validation of signed messages is verifi...

The dynamic nature of mobile ad hoc networks (MANETs) is attributed to several inherent characteristics, such as variable link behavior, node movements and changing network topology. Providing quality of service (QoS) in such a dynamic environment is very difficult. QoS-aware routing is one of the QoS support that provides QoS at the network layer....

The performance of a Mobile Ad hoc Network (MANET) is closely related to the capability of the imple-mented routing protocol to adapt itself to unpredictable changes of topology network and link status. The Optimized Link State Routing (OLSR) protocol is a one key of the proactive routing protocols for MANETs. It is based on the multi-point relays...

The performance of routing protocols in a mobile ad hoc network (MANET) is related to the network topology and nodes mobility. In order to ensure good performances of routing protocols in MANET, it is necessary to take into account the mobility criterion when choosing best routes in the network. In this paper, we propose a new measure of the networ...

The Optimized Link State Protocol (OLSR) routing protocol, is an optimization of link state protocols designed for mobile adhoc networks. OLSR is suitable for large and dense adhoc networks. For the learning routes process, it uses the flooding technique based on multipoint relays (MPR) which make it possible to reach all nodes in the network with...

The ad hoc on-demand distance vector (AODV) routing protocol, designed for mobile ad hoc networks, has two main objectives. First, it enables route establishment between a source and a destination node by initiating a route discovery process. Second, it maintains the active routes, which means finding alternative routes in a case of a link failure...
