Urban Traffic Monitoring and Modeling System: An IoT Solution for Enhancing Road Safety
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Qatar expects more than a million visitors during the 2022 World Cup, which will pose significant challenges. The high number of people will likely cause a rise in road traffic congestion, vehicle crashes, injuries and ...
Realization of dual-hop networks in Wi-Fi direct and performance evaluation
(
IEEE
, 2017 , Conference Paper)
Wireless LANs are used as a common choice of Internet access at homes, offices, campuses and public areas such as airports and supermarkets. Wireless LANs support device-to-device (D2D) communication using ad-hoc mode, ...
A new MAC design in LTE for MIMO multiuser schemes
(
IEEE
, 2013 , Conference Paper)
Long Term Evolution (LTE) supports closed-loop Multiple Input Multiple Output (MIMO) techniques, as a mechanism to improve system performance. An open topic since the appearance of MIMO is whether the feedback load, that ...

(
IEEE Computer Society
, 2013 , Conference Paper)
Femtocell is a promising technology that will improve wireless resources efficiency through frequency spatial reuse however, its integration with the current cellular systems has been considered a fundamental challenge. ...
Enhanced service delivery for cognitive systems within multiple antenna scenarios
(
IEEE Computer Society
, 2013 , Conference Paper)
Multiple Input Multiple Output (MIMO) is a well established technology that when jointly considered with Cognitive Radio (CR) it will create interactions that need to be optimized. The capability to provide service to more ...
A novel energy saving MIMO mechanism in LTE systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
Long Term Evolution (LTE) supports closed-loop MIMO techniques to improve its performance, but in order to exploit multiuser MIMO channel capabilities, the design of an efficient MAC scheme that supports Multiuser MIMO is ...
Energy optimization in unsynchronized TDD systems for joint uplink downlink scheduling
(
IEEE
, 2013 , Conference Paper)
Energy is an important resource in wireless communications systems that has to be optimized in order to guarantee low interference in the network as well as efficient use of the available resources. One of the prominent ...

(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
In this paper we evaluate the energy efficiency of MIMO technologies introduced in the emerging IEEE 802.11n standard for infrastructure based WLANs. The main focus is on exploiting multiuser capabilities of MIMO technologies, ...
A modified joint uplink-downlink opportunistic scheduling for Quality of Service guarantees
(
IEEE
, 2013 , Conference Paper)
Quality of Service (QoS) is a very important metric in wireless communication systems, where both Uplink (UL) and Downlink (DL) connections request strict QoS demands in terms of rate, delay, etc. for their proper operation. ...
Enhancing the quality of experience of video streaming in LTE networks using distributed antenna systems
(
IEEE
, 2013 , Conference Paper)
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 ...
