If you want to learn more about Provisioning Quality of Experience in future 6G Networks I recommend our recently published article in IEEE Xplore https://lnkd.in/duP7ZYN9. It provides a concise overview about use of a model to predict QoE and enable adaptive QoS in the 6G radio access networks.

This work investigates the coexistence of multiple #further-#enhanced #mobile #broadband (#feMBB) and #ultra-#massive #machine-#type #communication (#umMTC) wireless sources in a network. In order to enhance the achievable connectivity, each orthogonal resource block of the network is assigned to one feMBB and multiple umMTC sources. FeMBB sources are assumed to constantly transmit, while umMTC is considered to access the network in a probabilistic manner. If more than one umMTC sources attempt to access the network in a given resource block, no umMTC transmission is permitted, however, when precisely one umMTC source endeavors to access the medium, rate-splitting multiple access is employed to concurrently serve both feMBB and umMTC transmissions. For such a communication scenario, the authors derive novel closed-form expressions for sources’ outage probabilities (#OPs), ergodic rates (#ERs), system throughput, and ergodic sum rate under both the ideal case of perfect channel state information (#pCSI) and perfect successive interference cancellation (#pSIC) and the more realistic scenario of imperfect CSI (#ipCSI) and imperfect SIC (#ipSIC). ----Athanasios Chrysologou, Sotiris Tegos, Panagiotis Diamantoulakis, Nestor Chatzidiamantis, @Paschalis Sofotasios, @George Karagiannidis More details can be found at this link: https://lnkd.in/gQs8t_8K

50 years ago today vint cerf and Bob Kahn published their paper on packet switching which is the basis for the Internet we use today. They did come up with TCP: "Within a HOST we assume that existence of a transmission control program (TCP) which handles the transmission and acceptance of messages on behalf of the processes it serves." It was published in IEEE Transactions on Communications ( Volume: 22, Issue: 5, May 1974): https://lnkd.in/dty7AhYw A protocol that supports the sharing of resources that exist in different packet switching networks is presented. The protocol provides for variation in individual network packet sizes, transmission failures, sequencing, flow control, end-to-end error checking, and the creation and destruction of logical process-to-process connections. Some implementation issues are considered, and problems such as internetwork routing, accounting, and timeouts are exposed. https://lnkd.in/dFcmXfKp

Discovering the power of the TCP/ IP protocol suite in the 1980s changed my life.

50 years article on packet switching. 😍 Being able to read the whole document again and see that after 50 years these concepts continue to be the basis for the internet is incredible.

🚀 Excited to share that my latest paper, titled “Enhancing QoE in HTTP/3 Using EPS Framework,” has been published in the 2024 International Conference on Computer, Information and Telecommunication Systems (CITS)! 📄 In this paper, we propose a mixed scheduling mechanism combining incremental and non-incremental resource delivery, guided by EPS urgency levels, to enhance the Quality of Experience (QoE). Additionally, we introduce an EPS priority mapping based on Chromium’s priority indicators and resource types, which further improves website performance metrics, especially for sites with a large number of resources. 🔗 Check out the paper on IEEE: https://lnkd.in/gxs2upQw 🔗 Author’s copy: https://lnkd.in/gbg2eqqT #HTTP3 #QoE #EPS #QUIC #WebPerformance #CITS2024 #NetworkScheduling

Thanks Vint and Bob!

This paper deals with scenario-aware, uncoordinated, and distributed signaling techniques in the context of feedforward opportunistic communications, that is, when the opportunistic transmitting node does not cooperate with any other node in a heterogeneous communication context. In this signaling technique, each network node individually follows a transmission strategy based on the locally sensed occupied and unused physical-layer network resources to minimize the induced interference onto other coexisting networks, taking into account the impact of the sensing errors and the locality of the sensing information. ----Gregori Vazquez More details can be found at this link: https://lnkd.in/gx5j-Jdt

This paper formulates a general model for all jamming modes and signal types. The authors propose novel methods to eliminate the interfering signals and securely estimate the needed signals for a network model with two legitimate nodes exchanging information via a relay. The method for the varied signal is generalized into a theorem such that it can be also used in a scenario different from the security scenario. They exploit the ratios of the channel between each jammer and a certain antenna of a receiver to the channel between that jammer and the rest of the antennas of that receiver to estimate the needed signals. ----@Chan Dai Truyen Thai, Vo Nguyen Quoc Bao, Son Nguyen More details can be found at this link: https://lnkd.in/gY55WD7r
