Cím:3D GIS - A Major Step Analysis to Evaluate Convenient Healthy Residential District Based on Environmental Sensory Data Sets / Aldabbas Ashraf Khaled Abd Elkareem, Gál Zoltán, Korteby Mohamed Amine
Dátum:2018
Megjegyzések:Utilization of precise 3D spatial network pattern can provide an essential refinement in vehicle routing, significantly, this kind of models magnify eco-routing, in which decreases the ecological effect of motor transportation. We come up with a novel sifting technique to determine the CO2 emission level based on sensory data that are extracted from 2D spatial network framework model with a combination of information obtained from aerial laser scan, which is used to produce an accurate 3D modeling. In this paper, we present an environment quality evaluation to estimate convenient healthy residential district based on environmental sensory dataset which is an important task of environmental protection and providing a healthy lifestyle. The evaluation process involves complicated procedures which include loading the collected data, generating 3D GIS map, data analysis of 3D GIS map for the CO2 emission level, then the quality evaluation can be decided through the feasible produced map.

Cím:Entropy Analysis of Hierarchical Routing in Heterogeneous Wireless Sensor Network / Zoltan Gal, Djamila Talbi, Amine Korteby
Dátum:2024
Megjegyzések:Sparing energy during data transfer in Wireless Sensor Networks (WSN) requires the main communication facility of the Internet of Things (IoT) services. The hierarchical approach of cluster preparation is considered a de facto mechanism in the WSN systems. The creation of the clusters and election of the cluster head (CH) remains one of the most intensively analyzed mechanisms because the interference of the sensor nodes strongly affects the system performance. The entropy measures the uncertainty level of a system. Disjunctive subsystems may or may not be correlated. The more the subsystems are independent, the more approaches from above the sum of subsystems' entropy to the entropy of the union system. The spatiotemporal distribution of the CH has a big impact on the consumed energy by the WSN radio interfaces and the overall life cycle of the sensor communication system. A typical instance of the two-level hierarchical routing mechanisms is the Low-Energy Adaptive Clustering Hierarchy (LEACH) considering just the physical distance between the potential members of the clusters. We proposed a Cost-Balanced LEACH (CB-LEACH) with a moving Sink node (SN) in the previous study. Both the distance and the remaining energy of the nodes were used in the CH election step. We proved previously that CB-LEACH significantly outperformed the classical LEACH when a cost balance metric based on the actual global status of the WSN (mean and standard deviation of the nodes' energy and the nodes' relative distance) was applied in the CH election step. In this study, heterogeneity of the analyzed WSN was marked by two groups of sensor nodes spread uniformly randomly in the same physical area, each group of nodes having different amounts of initial energies. Based on the newly proposed metric called Inter-Subsystem Mutual Effect (ISME), we investigated the effect of the heterogeneity in the CB-LEACH system using energy-entropy (EE) and distance-entropy (DE). The relative difference of these entropies indicates the interference of the subsystems.

Cím:Impact of Modulated Routing Mechanism on Wireless Sensor Network Systems: A Comprehensive Analysis / Zoltan Gal, Amine Korteby, Djamila Talbi
Dátum:2023
Megjegyzések:Wireless Sensor Networks (WSNs) have been hugely advanced in recent years, driven by the growth of equipment types and numbers and the reduction of cost. Various services have been provided based on application requirements and network services. Among the energy-saving solutions in WSN environments, the Low Energy Adaptive Clustering Hierarchy (LEACH) mechanism stands out. This hierarchical protocol makes cluster heads aggregate and switches data sent by the cluster entity nodes toward a fixed Sink node. In this study, we proposed Cost Balanced LEACH (CBLEACH), a novel set of routing mechanisms that introduce the mobility aspect to the Sink node (SN) and balances the decision of cluster head (CH) election by considering the distances between nodes and the residual energy of expected CH candidates. CB-LEACH allows nodes to be close to the SN to transmit data directly, ensuring non-collapsing energy and achieving the greatest efficiency in the WSN. The functionalities and features of the CB-LEACH routing mechanism were explored to provide valuable insights for researchers and practitioners in WSNs. We introduced a balance factor variable that merged the two impacting and time-dependent properties of nodes: distance and energy. The CH election in each cluster was based on a cost rule derived from a linear Eq. of the balance factor. We presented four different modulation schemes for the balance factor, each with its own rule, and analyzed their impact on the CB-LEACH mechanism. We examined the system's functionalities and compared the lifetime and transmitted number of frames in different scenarios involving the epoch number, the speed of SN, and various systems including Direct Sequence, basic LEACH, enhanced LEACH with mobile SN, and CB-LEACH. The findings in this study demonstrated that the modulated CB-LEACH routing mechanism outperformed other routing cases, offering superior features and capabilities to the WSNs.

Cím:Energy Sparing Of The Leach Communication Mechanism in Heterogeneous WSN / Zoltán Gál, Mohamed Amine Korteby
Dátum:2019
ISSN:2231-5403
Megjegyzések:In current years, there have been a large progress in Wireless Sensor Networks (WSN) due to their development in term of hardware and cost reduction. Plenty of routing protocols have been proposed and developed depending on the application and network architecture. One of the most efficient energy management of the wireless sensor network nodes is provided by the LEACH (Low Energy Adaptive Clustering Hierarchy) mechanism. This hierarchical protocol uses cluster head function of the nodes to aggregate and forward the messages from the cluster members to the Sink node. Each node decides to become cluster head stochastically in each epoch time intervals. Nodes have enough energy to reach directly through radio channel any of the nearest cluster nodes, as well as the sink node. Optimization algorithm is required to provide efficient energy consumption on the WSN clusters level. A node being cluster head in the actual epoch time can repeat this function just with a probability p in time. Classical nodes find the nearest cluster head to minimize the transmission energy consumption and use time division multiple access method (TDMA)to send the radio frames in each epoch time. In this paper we use own developed simulation method and software to analyze the remaining energy process in time of the whole WSN network and the number of forwarded frames in function of the probability p for a set of nodes having heterogeneous levels of the initial energy.

Cím:Estimation of the Wireless Sensor Network Performance using Fractal Behavior of the Generated Cognitive Harmonic Waves / Zoltan Gal, Amine Korteby, Ashraf AlDabbas
Dátum:2018
Megjegyzések:In several domains like geometry and music, a classic kind of discrete pattern comes from similar systems, where the elements of the set are connected in a specific structure. Types of the similarity feature are symmetry with respect to the axis or to the origin, rotation, translation, and scaling. A special group of structure types with similarity character in different natural and artificial systems are fractals. They are set of objects that look similar on different scales. A musical fractal is a piece where the theme harmonizes with a slow down version of itself, that way the small-scale structure of the piece is repeated at a larger scale. Human matter of taste prefers fractal structure in music and is tight sensible to the similarity alteration. This phenomenon is used to evaluate the operating performance of the Wireless Sensor Network (WSN). We present a new method of sensing the WSN behavior based on cognitive generation mechanism of a musical sound signal and we give special features of this algorithm.

Cím:Impact of the delay tolerance in wireless sensor networks : Buffer occupancy and energy consumption aspects / Zoltan Gal, Mohamed Aminde Korteby, Ashraf Dabbas
Dátum:2018
Megjegyzések:Wireless Sensor Networks have altered our way to collect scientific data and acknowledging our environment. They are network of low power self-sufficient node that can achieve any given task and sense diverse phenomena (Temperature, Humidity). Wildly used in the battlefield, wildlife tracking, and vehicular communication, they allow people to connect without setting up expensive or impossible network infrastructure. The performance analysis of WSN's plays a key role in understanding their design and behavior because of the lack of network resources as they have less energy and memory to buffer transit messages. Therefore, it is important to exploit these resources efficiently. In this paper, we present analysis of three different routing protocols under four movement models with nine Time-To-Live (TTL) values for a simulation of ten hours each. We give details concerning the impact of the delay tolerance to the buffer occupancy, energy consumption of the nodes under three hundred twenty-four different scenarios.

Cím:Multi dimensional analysis of sensor communication processes / Mohmamed Amine Korteby, Zoltán Gál, Péter Polgár
Dátum:2021
ISSN:1787-5021 1787-6117
Megjegyzések:The Internet of Things requires communication mechanism to be optimal not only from the data transfer but from the energy consumption point of view, too. One of the most analyzed types of the sensor network is Low Energy Adaptive Clustering Hierarchy (LEACH) system depending on the population density, algorithm of cluster head election, heterogeneity of the energy and physical position of the nodes, velocity of the sink node, data aggregation rate and size of the data frame. Complexity of the system has been analyzed based on status data series of 360 simulation cases. New family of wireless sensor network (WSN) system is proposed with name CB-LEACH, having better characteristics than the classical LEACH system. The service ability of sensor network and dependency properties was done with analytic technique based on Singular Value Decomposition (SVD). Using this method there were identified most important modes serving as basis to regenerate responses of the studied sensor systems. It was found that the number of significant modes is just six. The novelty of the paper is a proof of concept that SVD is a useful multidimensional tool which can be used for describing the behavior of the newly proposed CB-LEACH family of sensor network mechanisms.

Cím:Energy Sparing of the Leach Communication Mechanism With Mobile Sink Node / Mohmamed Amine Korteby, Zoltán Gál
Dátum:2020
ISSN:1613-0073
Megjegyzések:In the process of crafting routing protocols for Wireless Sensor Networks (WSN), clustering became an important aspect to spare network energy consumption and data delivery efficiently. Low-Energy Adaptive Clustering Hierarchy (LEACH) is a hierarchical cluster-based, energy-efficient routing protocol. It extends the network lifetime by randomly selecting Cluster Heads (CH) to aggregate and forward the routing information from the cluster members to the Sink node. LEACH in its archetype is a distributed routing protocol and one of the most efficient energy management mechanism for WSN. However, there exist some disadvantages, that lead to uneven energy consumption in the network when the nodes far away from the Sink die more quickly than the nodes closed. Hence, we propose a new approach for network lifetime improvement, where the Sink node is mobile and cross the whole network physical area to have a better energy consumption rate uniformly distributed across the network.

Cím:Impact of the Geographic Map Based Movement on the Communication Quality of Sensor Networks / Mohamed Amine Korteby, Zoltán Gál, Ashraf Dabbas
Dátum:2018
Megjegyzések:Several Wireless Sensor Network (WSN) applications function autonomously in defective or unreachable environments, preventing maintenance or human intervention. Redundant deployment is usually considered in this scenario, making the network robust to failure and environmental changes. New applications need a connection of end-to-end delay and high reliability for various communication models. In current WSNs, the QoS deteriorates upon augmented traffic load due to congestion, the shared medium, large number of hops in data routing and the overall coverage area issue. This paper investigates the impact of the Shortest Map-Based movement model on the quality of service (QoS) of the sensor network, under three routing protocols with nine Time-To-Live (TTL) values for a simulation of ten hours each.

Cím:Perception of delay tolerant network behavior with cognitive sonification controller / Mohamed Amine Korteby, Zoltan Gal
Dátum:2017
Megjegyzések:IEEE catalog number: CFP1726R-ART
Delay Tolerant Networking (DTN) allows communication in challenging and harsh environments where traditional networking fails and new routing and application protocols are required. For such networks, it is a constant task to keep track and a summary of their behavior because of the lack of network resources as they have less energy and memory to buffer transit messages. Therefore, it is important to exploit these resources efficiently. Several studies propose that accompanying visualization with sonification can ease some of the challenges of constant visual monitoring. In this paper, we simulate three different routing protocols and four movement models to analyze the energy consumption, the buffer occupancy and the interconnection time of the nodes under forty-eight different scenarios. Furthermore, we propose a cognitive sonification controller system and to enhance the network administrators in their network management task.
