1. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications
Sammanfattning : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. LÄS MER
2. Provisioning Strategies for Transparent Optical Networks Considering Transmission Quality, Security, and Energy Efficiency
Sammanfattning : The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand. LÄS MER
3. Physical Layer Security Issues in Massive MIMO and GNSS
Sammanfattning : Wireless communication technology has evolved rapidly during the last 20 years. Nowadays, there are huge networks providing communication infrastructures to not only people but also to machines, such as unmanned air and ground vehicles, cars, household appliances and so on. LÄS MER
4. Performance Analysis of Cognitive Radio Networks under Spectrum Sharing and Security Constraints
Sammanfattning : The cognitive radio network (CRN) concept has been proposed as a solution to the growing demand and underutilization of the radio spectrum. To improve the radio spectrum utilization, CRN technology allows the coexistence of licensed and unlicensed systems over the same spectrum. LÄS MER
5. Design and Identification of Wireless Transmitters for a Low-power and Secure Internet of Things
Sammanfattning : Wireless communication is a key enabler for connecting billions of Internet of Things devices. For networked embedded devices operating on limited energy resources, wireless communication dominates the power consumption. LÄS MER
