1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

2. Optimization of Physical Uplink Resource Allocation in 5G Cellular Network using Monte Carlo Tree Search
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Physical Uplink Control Channel (PUCCH), which is mainly used to transmit Uplink Control Information (UCI), is a key component to enable the 5G NR system. Compared to LTE, NR specifies a more flexible PUCCH structure to support various applications and use cases. LÄS MER
3. Fuzzing Radio Resource Control messages in 5G and LTE systems : To test telecommunication systems with ASN.1 grammar rules based adaptive fuzzer
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 5G telecommunication systems must be ultra-reliable to meet the needs of the next evolution in communication. The systems deployed must be thoroughly tested and must conform to their standards. Software and network protocols are commonly tested with techniques like fuzzing, penetration testing, code review, conformance testing. LÄS MER
4. A Simulation Study on the Performance Comparison of the V2X Communication Systems: ITS-G5 and C-V2X
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Personlig rörlighet och fordonstransportsystem genomgår en förskjutning mot mer reaktiv och intelligent transportinfrastruktur. Ett brett spektrum av applikationer och användningsfall har dykt upp i fordonsmiljön underlättad av olika trådlösa kommunikationssystem. LÄS MER
5. Improved Precision Time Protocol with Relative Clock Phase Information
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : A common time reference among nodes is one of the key requirements in telecommunication, distributed control systems and industrial automation systems. For instance, 3GPP LTE TDD standard requires at least ± 1.5 µsec time accuracy among base stations in order to resolve uplink and downlink transmission. LÄS MER
