The existing Private/Professional Mobile Radio (PMR) technologies designed specifically for Mission Critical Communication (MCC) systems are narrowband and wideband devices, with limited network data capacity in emergency scenarios. They are majorly used to support MCC voice communications and low data rate applications during mission critical operations. However, the need for broadband systems that...
The growing demand for mobile multicast services, such as Internet Protocol television (IPTV) and video streaming, requires effective radio resource management (RRM) to handle traffic with strict quality-of-service constraints over Long-Term Evolution (LTE) and beyond systems. Special care is needed to limit system performance degradation when multiple multicast streams are simultaneously transmitted...
The Long Term Evolution (LTE) network is recognized as the next generation wireless network, which provides high bandwidth and low latency for emerging mobile applications. The issue of power saving is very crucial for the success of service deployment. This paper presents a novel downlink scheduling approach to reduce power consumption while maintaining the receiving quality of video streaming in...
The concern over the quality of delivering video streaming services in mobile wireless networks is addressed in this work. A framework that enhances the Quality of Experience (QoE) of end users through a quality driven resource allocation scheme is proposed. To play a key role, an objective no-reference quality metric, Pause Intensity (PI), is adopted to derive a resource allocation algorithm for...
Long Term Evolution (LTE) is considered the most promising cellular system able to support the growing demand of multicast services (e.g., IPTV, video streaming) over mobile terminals. The design of effective strategies for the management of these applications is still an open issue, especially in scenarios where several multicast streams are simultaneously transmitted in a cell. In this paper we...
Video transmission over long term evolution (LTE) networks is studied. The use of distributed antenna systems (DAS) is proposed to enhance the video quality of experience (QoE). Real time video streaming over both the uplink (UL) and downlink (DL) directions is investigated. LTE dynamic resource allocation is taken into account, and several types of DAS deployments are analyzed and compared. Simulation...
Long Term Evolution (LTE) represents the cutting-edge broadband wireless access technology in providing ubiquitous and simultaneous connectivity to many users. This paper evaluates the impact that packets breaking the 1500 bytes legacy value, called Jumboframes, have in LTE networks, by exploiting and extending the network stack in the ns-3 simulator. We first provide an overview about the key features...
In this paper we implement and evaluate two scheduling techniques for mixed data traffic (VoIP and Video Streaming-VS) in LTE systems. We present results regarding resources allocation and traffic evaluation (mean throughput per user) for the Best CQI scheduler and compare to those for a Round Robin (RR) scheduler. Both services are delay-critical services but by prioritizing VoIP in the Best CQI...
Long term evolution (LTE) is the next generation wireless system that supports all IP transmission for multimedia services. The quality of service (QoS) requirements of multimedia services are one of the major challenges that need to be addressed by packet scheduling in the LTE system. This paper proposes a new resource allocation technique for real time (RT) video streaming applications in the downlink...
