1. Cognitive Radio Networks : Elements and Architectures
Sammanfattning : As mobility and computing becomes ever more pervasive in society and business, the non-optimal use of radio resources has created many new challenges for telecommunication operators. Usage patterns of modern wireless handheld devices, such as smartphones and surfboards, have indicated that the signaling traffic generated is many times larger than at a traditional laptop. LÄS MER
2. Power and frequency assignment in HF Radio Networks
Sammanfattning : .... LÄS MER
3. On the Performance of Underlay Cognitive Radio Networks with Interference Constraints and Relaying
Sammanfattning : Efficiently allocating the scarce and expensive radio resources is a key challenge for advanced radio communication systems. To this end, cognitive radio (CR) has emerged as a promising solution which can offer considerable improvements in spectrum utilization. LÄS MER
4. Transport Analytics Based on Cellular Network Signalling Data
Sammanfattning : Cellular networks of today generate a massive amount of signalling data. A large part of this signalling is generated to handle the mobility of subscribers and contains location information that can be used to fundamentally change our understanding of mobility patterns. LÄS MER
5. Error mitigation in industrial wireless sensor networks : Corrupted packet forensics and recovery
Sammanfattning : Wireless sensor networks (WSN) are gradually penetrating the industrial automation domain. This process is, however, inhibited by a number of challenges that need to be considered and addressed before WSN can serve the most demanding industrial applications. LÄS MER
