Third Generation Partnership Project (3GPP) standardizes the Long-Term Evolution (LTE) to improve the quality of service in modern communication systems using 3GPP LTE-advanced (LTE-A) networks. As this technology is converging with modern devices, efficient resource allocation schemes are essential for minimization of the communication delay for the sensitive real-time devices. To achieve the demands of latest technologies, this paper proposes two novel mechanisms, enhanced real-time polling system with continuous time-batch Markovian arrival process and proactive resource allocation framework. The objective of the former mechanism is to improvise the service connectivity between the multimedia devices in LTE-A networks and the latter is to exploit the transmission bits in each user's buffer in addition to the state information of wireless channel. The proposed mechanisms consider the constraints enforced by 3GPP standard in terms of radio resource blocks allocation for LTE-A networks. In addition, the proposed mechanisms use LTE-A networks to investigate the Voice over LTE traffic in order to analyze various quality-of-service measures, namely, sum throughput, session setup delay, packet delivery ratio, resource utilization ratio, and throughput improvement via real-time multimedia client-server systems. The probing results show that the proposed algorithm is superior in comparison to other typical services of IEEE 802.16d/e-based systems as well as LTE-A system with 7 orthogonal frequency-division multiplexing symbols over a duration slot better throughput performance in comparison with existing mechanisms.

Tuna, Nur Nagihan; Hasdoğan, Gülay Fatma; Department of Industrial Design (2020-11-2)
Internet of things (IoT) introduced some challenges as well as many opportunities for designers. Enhanced capabilities of the things transformed them from being passive assistants of humans to active agents that can collect and act on data. On the one hand, the emergence of new and more capable ‘things’ constitutes challenges for designers. Most of the studies are technology-driven, and the unprecedented experiences that designers cannot envision might result in disappointing experiences for users. On ...

Analysis and design of dual-polarized wideband patch antennas electromagnetically excited with elevated wide strips /
Yılmaz, Adil Fırat; Alatan, Lale; Department of Electrical and Electronics Engineering (2015)
In communication systems like WiMAX, WLAN, 3G, 4G and LTE, design of wideband and dual polarized antennas are required. It is known that bandwidth of patch antennas can be broaden by using thick air substrates. The bandwidth can be further improved by using three dimensional feed strucutures that are electromagnetically coupled to the patch. In this thesis, microstrip patch antennas that are excited by elevated wide strips are studied. First, a linearly polarized antenna is considered and the effects of ant...
