A cooperative Q-learning approach for distributed resource allocation in multi-user femtocell networks
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)This paper studies distributed interference management for femtocells that share the same frequency band with macrocells. We propose a multi-agent learning technique based on distributed Q-learning, called subcarrier-based ... -
Characterization of tbm muck for construction applications
( MDPI , 2021 , Article)This paper investigates the potential utilization of the Tunnel Boring Machine (TBM) muck generated from Doha's Metro Gold Line in different construction applications. The properties of the raw TBM muck were studied, and ... -
Demonstrating the Worth of Recycled Aggregates - A Case Study from Qatar
( American Society of Civil Engineers (ASCE) , 2016 , Conference Paper)Recycled aggregates are widely used in unbound applications in many countries. However, in some areas the materials available may not meet all the requirements of the local specifications. This is the case in Qatar, where ... -
Distributed interference management using Q-Learning in cognitive femtocell networks: New USRP-based implementation
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)Femtocell networks have become a promising solution in supporting high data rates for 5G systems, where cell densification is performed using the small femtocells. However, femtocell networks have many challenges. One of ... -
Intercalation of ionic liquids into bentonite: Swelling and rheological behaviors
( Elsevier B.V. , 2016 , Article)In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ... -
Location privacy preservation in secure crowdsourcing-based cooperative spectrum sensing
( Springer International Publishing , 2016 , Article)Spectrum sensing is one of the most essential components of cognitive radio since it detects whether the spectrum is available or not. However, spectrum sensing accuracy is often degraded due to path loss, interference, ... -
Modeling and analysis of HetNet interference using Poisson Cluster Processes
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)Future mobile networks are converging towards being heterogeneous, owing to the co-existence of multi-tier networks within the same geographical area, including macro, pico- and femto-cells. The deployment of such networks ... -
On ergodic capacity of wireless transmission subject to poisson distributed interferers over rayleigh fading channels
( IEEE , 2013 , Conference Paper)Poisson point process has been widely adopted in the analysis of co-channel interference in dense frequency reuse systems. With the decaying power law, the aggregate co-channel interference in Poisson field can be viewed ... -
Properties of fibre-reinforced concrete made with discarded materials
( ICE Publishing , 2019 , Article)This research paper investigates the physical, chemical and mechanical properties of steel slag aggregates (SSA), gravel aggregates (GLA), natural gabbro aggregates (NGA), and the different fresh and hardened properties ...
