Voice over Internet Protocol (VoIP) has evolved over the years, being a real-time service. VoIP has been coupled to different technologies, one of them is WiFi, which is one of the most used for wireless local area networks in domestic and commercial environments. In this paper, we evaluate the performance of wireless scenarios by considering VoIP traffic, based on WiFi technology in conformance with IEEE 802.11b/g in interfered outdoor scenarios, by considering an intrusive injection traffic technique, for codecs G711 (1 sample), G711 (2 samples), G723, G729 (2 samples), and G729 (3 samples), related to the main metrics associated to Quality of Service (QoS) parameters. Our results show the best performance was obtained with the codecs G723 and G729 (3 samples), obtaining up to 30 simultaneous voice connections with optimal values of delay, jitter and packet loss according to the recommendations given for VoIP by ITU-T, while the worst performance was obtained with the codec G711 (2 samples), obtaining only 5 simultaneous voice connections, reaching an efficiency loss of around 18% in a co-channel interference scenario.

Coverage and Capacity Performance Degradation on a Co-Located Network Involvi...Onyebuchi nosiri
The document investigates the performance effects of noise rise caused by spurious emission from a co-located jammer on the coverage radius and system capacity of a CDMA2000 and WCDMA network. Measurements were taken to evaluate the impact of increasing noise rise on these parameters. The results showed that as noise rise increased due to spurious emission, the coverage radius and number of supported users decreased, reducing system capacity. A noise rise of 2dB represented a 15 user reduction and 33% lower capacity. The study concludes noise rise degradation impacts must be controlled to maintain desired coverage area and capacity performance.

Implementation of Particle Swarm Optimization Technique for Enhanced Outdoor ...Onyebuchi nosiri
This paper describes the development of optimized model for urban outdoor coverage in Long Term Evolution (LTE) network at 2300 MHz frequency band in Port Harcourt urban region, Nigeria. Signal attenuation and fluctuation remain amongst the major channel impairments for mobile radio communication systems. This arises as a result of model incompatibility with terrain and Line of Sight (LOS) obstruction of the channel signals. Some path loss models such as OkumuraHata, COST 231, Ericsson 999, Egli and ECC-33 models were evaluated for suitability and compared with the modified model for the environments. The models were based on data collected from LTE base stations at three geographical locations in Port Harcourt namely- Rumuokoro, Eneka and Ikwerre roads respectively. The simulation was implemented using MATLAB R2014a software. The modified model was further optimized with some selected parameters such as Root Mean Square Error (RMSE) and Mean Absolute Error (MAE) using Particle Swarm Optimization (PSO) technique. The results obtained gave rise to 3.030dB for RMSE and 0.00162dB for MAE respectively. The results obtained from the PSO optimized model demonstrated a better performance which is suitable for cell coverage planning and smooth handoff processes.

For multi-transmitter identification, machine learning achieves 70-80% accuracy for 2-5 users, outperforming signal processing which achieves 50% accuracy. However, signal processing is faster. The document generates test data using GNU radio and evaluates algorithms like K-nearest neighbor and maximum likelihood for the tasks. It concludes machine learning has higher accuracy but signal processing is faster, so algorithm
Quality of service improvement, Handoff Prioritization and Channel utilizatio...IJERA Editor
1. The document discusses call admission control and quality of service improvement techniques for cellular networks. It aims to reduce dropped handoff calls and improve quality of service by reducing grade of service.
2. It proposes prioritizing handoff calls over new calls by using guard channels reserved for handoffs or queuing handoff calls. This reduces the handoff call dropping probability at the cost of increased new call blocking probability.
3. It introduces a call admission control algorithm that considers both new and handoff call quality of service requirements to maximize resource utilization while minimizing the dropping probabilities of both call types.

This document analyzes quality of service (QOS) parameters in UMTS networks based on handovers and sectorization. It discusses:
1) Handovers play a major role in continuing services as users move between cell boundaries. Sectorization divides cells into sectors using directional antennas to reduce interference and increase capacity.
2) Simulations are conducted using OPNET to analyze soft and hard handovers as a user moves between sectors. Results show the active cell count changes and cells added and removed from the active set.
3) Analysis of soft and hard handovers using applications like HTTP shows that soft handovers provide better performance with lower object and page response times, ensuring seamless service continuity.
Improved Fuzzy Logic Controller for a Global Mobile Telecommunication NetworkIRJET Journal
This document presents an improved fuzzy logic controller for call admission in global mobile telecommunication networks. It develops a two-phase fuzzy logic model. The first phase is a Fuzzy Policer that optimizes call delivery and dropping using queue capacity, call bit rate, and call burst rate. The second phase is a Fuzzy Congestion Controller that adjusts the handoff queue capacity based on call mobility and available channels to prevent congestion. It outputs the adjusted queue capacity to the Fuzzy Policer. The model was found to outperform existing systems by minimizing call drop rates and reducing network congestion under varying traffic loads.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

21. Application
Intrusive testing:
Insertion of a reference speech
sequence
Acquiring the transmitted, distorted
speech sequence
Calculation of the speech quality by
comparing to the reference
Output: MOS LQOn – mean opinion
score, objective, narrowband

23. Not Intrusive Testing - ITU-T P.563
Listening speech quality prediction based
on speech signal in a call
No reference file insertion required
Average listening speech quality prediction
on statistical evaluation of a high number
of calls on the same connection
Not recommended for test on a call by
call basis
Much less reliable than intrusive testing
based on P.862 and P.863

24. The wideband challenge
High quality expectation by the user
Wideband must be significantly
better in all quality aspects
Significant contribution to quality by
the terminals
First attemt to certify high quality
wideband speech transmission:
GSMA

26. Wideband Network Planning –
ITU-T G.107.1
The principle of the model is identical to
the narrowband version G.107
The model reflects the improvements in
quality in wideband:
Maximum R = 129 (instead of 100 for
narrowband)
Model provides new wideband R calculation
mapping R to the range of 0-100
All factors – R0 and Impairment factors are
adapted accordingly

27. Wideband Network Monitoring
Setup as in narrowband
Only intrusive testing available
Network monitoring is based on ITU-
T P.863 POLQA
ITU-T P.862 PESQ should not be
used in wideband

28. Conclusions and Recommendations
ITU-T provides models for planning and
monitoring
Network planning is essential for achieving
high network QoS
Network monitoring is essential to detect
potential issues – e.g. changing radio
conditions, changing network conditions
(jitter, packet loss)
Both is not sufficient to guarantee a good
QoE – terminals play a major role for the
overall speech quality
