| 10 | Six Generation Load Cells Solution Based Congestion Management Control Purpose显示文摘Several assessing efforts are approved making both communication and information technologies available.In addition to being a part of universal access and service,we aim at assessing the impact of radio access technologies on universal access indicators.The proposed work demonstrates the possibility of inter-working of all existing Radio Access Technologies(RATs),in a limited area presented in the Six Generation Radio Resources Allocation(6 G-A)network.We propose a solution for the Vertical hand Over(VHO)in 6 G-A heterogeneous system,that adopts Media Independent Handover(MIH)protocol to benefit between different used technologies in a direct communication firstly and facilitate,in addition,coordination between congestion controlmechanisms with themobilitymanagement entity.The mathematical model has been developed to deal with locality coverage and broadband needs,based on a methodological approach consisting in integrating parameters linked to access index through radio technologies.This approach has been applied.In practice,it has contributed to highlighting its relative simplicity of implementation,but it is not enough for sixgeneration system radio access networks.The congestion control mechanism is integrated within the vertical handover process,this proposition is used to prevent each presented congestion state.The media independent handover IS equipment,as well as six G-A equipment which are both considered as the whole architecture key equipment,perform and guaranty this related process.Efficient communication is established besides information exchange between various technologies.Achieved evaluation results are performant and prove that proposed mechanisms are efficient.Both simulation and tests results are accomplished. | Chafaa Hamrouni Aarif Alutaybi | 2023 | Computers, Materials & Continua2023，，3： | 0 |
| 11 | 5G Smart Mobility Management Based Fuzzy Logic Controller Unit显示文摘In the paper,we propose a fuzzy logic controller system to be implemented for smart mobility management in the 5G wireless communication network.Mobility management is considered as a main issue for all-IP mobile networks future generation.As a network-based mobility management protocol,Internet Engineering Task Force developed the Proxy Mobile IPv6(PMIPv6)in order to support the mobility of IP devices,and many other results were presented to reduce latency handover and the amount of PMIPv6 signaling,but it is not enough for the application needs in realtime.The present paper describes an approach based on the IEEE 802.21 Media Independent Handover(MIH)standard and PMIPv6,so we present a new vertical handover algorithm for anticipating handover process efficiently.Our object is to propose a smart mobility management that contribute in 5G wireless communication system network operating functions.Two proposed dynamic thresholds were successfully made to guaranty process triggering,and a new primitive MIH is proposed for signaling a needed handover to be done.Simulation results demonstrate a significant reduction of the handover delay,packet loss,handover blocking probability and signaling overhead.Simulation results and tests are accomplished. | Chafaa Hamrouni Slim Chaoui | 2022 | Computers, Materials & Continua2022，，6： | 0 |
| 12 | A New Fuzzy Controlled Antenna Network Proposal for Small Satellite Applications显示文摘This research contributes to small satellite system development based on electromagnetic modeling and an integrated meta-materials antenna networks design for multimedia transmission contents.It includes an adaptive nonsingular mode tracking control design for small satellites systems using fuzzy waveless antenna networks.By analyzing and modeling based on electromagnetic methods,propagation properties of guided waves from metallic structures with simple or complex forms charge partially or entirely by anisotropic materials such as metamaterials.We propose a system control rule to omit uncertainties,including the inevitable approximation errors resulting from the finite number of fuzzy signal power value basis functions in antenna networks.Moreover,both the stability and the tracking performance of the closed-loop robotic system are experimentally validated.The research lies within the scope of the improvement of speed,effectiveness,and precision of numerical methods applied to electro-magnetic modeling with complex structures,essentially rectangular metallic waveguides filled with isotropic or anisotropic metamaterials.Three axes of our research are presented:waveguides,filters,and antennas.The proposed controller does not require prior knowledge about the dynamics of the fuzzy system controller for antenna networks or the offline learning phase.In addition,this work contributes to solving the problem of non-visibility stations to ensure data transmission in wireless networks.The proposed solution maximizes inter-connection by using a fuzzy controlled antenna network,and the novelty guarantees nonlimited interconnection in wireless networks compared to traditional methods. | Chafaa Hamrouni | 2022 | Computers, Materials & Continua2022，，9： | 0 |
