Echo State Learning for User Trajectory Prediction to Minimize Online Game Breaks in 6G Terahertz Networks

Mobile online gaming is constantly growing in popularity and is expected to be one of the most important applications of upcoming sixth generation networks. Nevertheless, it remains challenging for game providers to support it, mainly due to its intrinsic and ever-stricter need for service continuity in the presence of user mobility. In this regard, this paper proposes a machine learning strategy to forecast user channel conditions, aiming at guaranteeing a seamless service whenever a user is involved in a handover, i.e., moving from the coverage area of one base station towards another. In particular, the proposed channel condition prediction approach involves the exploitation of an echo state network, an efficient class of recurrent neural network, that is empowered with a genetic algorithm to perform parameter optimization. The echo state network is applied to improve user decisions regarding the selection of the serving base station, avoiding game breaks as much as possible to lower game lag time. The validity of the proposed framework is confirmed by simulations in comparison to the long short-term memory approach and another alternative method, aimed at thoroughly testing the accuracy of the learning module in forecasting user trajectories and in reducing game breaks or lag time, with a focus on a sixth generation network application scenario.

Design of rectangular C-slot patch antenna at 2.95 GHz and 4.32 GHz for next generation network

A simple patch antenna using microstrip feed at low frequency 2.95 GHz and 4.32 GHz is proposed. This is obtained by cutting C-shaped slot in the rectangular patch part. The dimension of the C-shaped slot is around half-wavelength of the chosen frequencies. This work is meaningful as a commencement investigation level of next generation network applications. It is designed by using low cost, easily available FR-4 substrate with dielectric loss tangent 0.02, relative permittivity 4.4 and height 1.575 mm. The simulation is done using Ansoft HFSS and the radiation performance such as S 11 , VSWR, Gain, Radiation Efficiency, Radiation Patterns, and Surface Current Distributions are observed step by step and then final design is proposed. Proposed antenna design has impedance BW 21.05%, 68.51%, good Return Loss -45.42 dB, -23.09 dB, VSWR 1.01, 1.15, acceptable total gain 1.27, 1.45 and high radiation efficiency 103.56%, 90.63% at interest of frequency 2.95 GHz and 4.32 GHz respectively for NGN.

RETRACTED ARTICLE: Efficient and optimized design of a stacked patch microstrip antenna for next generation network applications

WiMAX technology is an emerging technology for next generation network. It is a wireless broadband communications technology based around the IEE 802.16 standard providing high speed data over a wide area. Although initially seen as a candidate for 4G, its use is decreasing, although it is used as WiMAX broadband and also for last mile links. In this paper, An Aperture coupled Stacked Patch Microstrip Antenna for WiMAX application is proposed. This antenna is designed to have H-shape patch with V shape slot at the ground to provide the WiMAX band (3.3–3.6 GHz) which is a licensed spectrum that has been allocated for broadband wireless access in numerous countries around the world and widely used in military applications. FR4 is used as the substrate material. The designed antenna is simulated using Ansoft High Frequency Simulation Software. The simulated and measured results are showing that the proposed antenna is producing the bandwidth of 300 MHz with the return loss value of − 25.1 dB.

A conformance test tool for next generation network applications and systems

AbstractThis paper describes the architecture and operations of a test system NGNAS‐SIOTP. NGNAS‐SIOTP is designed based on the Testing and Test Control Notation Version 3 (TTCN‐3) specifications for the conformance testing of next generation network applications and systems. By specifying conformance test cases in abstract level, the test cases are language and platform‐independent, and the implementation of the test cases can be more convenient. We use an Open Mobile Alliance (OMA) Browsing test case of XHTML Structure Module and an IP Multimedia Subsystem (IMS) test case of Replaces Extension Header Field to illustrate how conformance tests can be implemented and conducted in our NGNAS‐SIOTP. These test cases conform to the OMA Enabler Test Specification (Conformance) for OMA Browsing and RFC documents for IMS. Copyright © 2010 John Wiley & Sons, Ltd.
