The evolution of current wireless access communication networks, especially inside buildings, moves towards higher microwave carrier frequencies in order to support the ever-growing data traffic volumes. This causes significant infrastructure cost increments due to the complexity and increased number of antenna sites needed for a certain area of coverage.(More)
1Abstract — The current service-and device discovery protocols are not platform-and network independent. Therefore, proxy servers will be needed to extend the range of IP-based discovery protocols to non-IP domains. We developed an architecture of a proxy that enables UPnP devices and services to be discovered on the Bluetooth network and vice versa, and(More)
WLAN-UMTS integration in the UMTS-based approach can be performed either at the UMTS Core Network (CN) or Radio Access Network (UTRAN). Both interworking solutions provide the operator with additional license-free bandwidth and promise good handover performance. Integration at the radio access level has the advantage that the UMTS core network protocols(More)
In this work, we study the adaptability of well known cryptography algorithms to energy harvesting wireless sensor networks. We are particularly interested in algorithms that have the ability to adapt to varying power in such networks. Our investigations and implementation on hardware platforms indicate that it is optimal to precompute a few key stream(More)
TELECOMMUNICATIONS The undersigned hereby certify that they have read and recommend to the Faculty of Electrical Engineering, Mathematics and Computer Science for acceptance a thesis entitled " Combining relaying and base station coordination for improving cell-edge multiuser performance in 3GPP LTE-Advanced networks " by Peng Guan in partial fulfillment of(More)
Acknowledgement This thesis being finished stands for my significant step achievement of my life. It has given me the greatest confidence study and research on the wireless telecommunications field. It also will make a big influence on the rest of my life. Initially, I would like to thank Jinglong Zhou, MSc for his guidance and encouragement to me during(More)
VoIP packets, when transported over the Internet, experience loss and variable delay. The effect of the network not only depends on the background flows but also on the parameters of VoIP packets itself, such as VoIP packet size and the packet generation intervals. While higher sized packets experience more losses, they experience less delay jitter and(More)
