Characterization of the indoor-outdoor radio propagation channel at 2.4 GHz
Ahmed I.; Orfali S.; Khattab T.; Mohamed A. ( IEEE , 2011 , Conference Paper)We present the site-specific signal strength measurement results for path loss, shadowing, and fading in 2.4GHz band under typical harsh environment (high temperature 4050 C and humidity 8090%). We use spectrum analyzer ... -
Energy efficient mobile relay selection for two-hop wireless networks
Ahmed I.; Butt M.M.; Mohamed A. ( IEEE Computer Society , 2014 , Conference Paper)In this paper, we propose a relay selection strategy for randomly distributed multiple relays. A single relay is selected for transmitting signal from a fixed source to a fixed destination which requires minimum total ... -
Ethnographing Gender Roles and Power in Intercultural Communication in Qatar
Theodoropoulou I.; Ahmed I. ( Taylor and Francis Ltd. , 2018 , Article)This ethnographic study examines how gender roles associated with male and female Qatari students in intercultural communication courses in a university in Qatar are negotiated between them and their two female instructors ... -
Mitigation of voltage imbalance in power distribution system using MPC-controlled packed-U-cells converter
Ahmed I.; Al-Emadi N.; Gastli A.; Ben-Brahim L. ( John Wiley and Sons Ltd , 2019 , Article)Delivering high power quality in single-phase distribution has witnessed more challenges especially with the increased penetration of single-phase distributed generation (DG). This paper proposes a smart solid-state-based ... -

Ahmed I.; Mohamed A.; Fouly T.; Hu Y.C. ( IEEE , 2011 , Conference Paper)This article presents a concise survey of fairness-aware frequency domain resource allocation techniques in Wireless Mesh Networks (WMNs). Wireless mesh networks have emerged as a key technology for next generation application ... -
On the fairness of resource allocation in wireless mesh networks: A survey
Ahmed I.; Mohammed A.; Alnuweiri H. ( Kluwer Academic Publishers , 2013 , Article Review)This article presents a comprehensive survey of resource allocation techniques in Wireless Mesh Networks (WMNs). Wireless mesh networks have emerged as a key technology for next generation application specific multi-hop ... -
On the group proportional fairness of frequency domain resource allocation in L-SC-FDMA based LTE uplink
Ahmed I.; Mohamed A.; Shakeel I. ( IEEE , 2010 , Conference Paper)Localized single carrier frequency division multiple access (L-SC-FDMA) has been selected as the uplink transmission scheme in 3GPP Long Term Evolution (LTE) due to its low Peak to Average Power Ratio (PAPR) over OFDMA in ... -
On the joint scheduling and intra-cell interference coordination in multi-relay LTE uplink
Ahmed I.; Mohamed A. ( IEEE , 2012 , Conference Paper)The relay-assisted Long Term Evaluation (LTE) cellular system is one of the most promising technologies to enhance the throughput and coverage of the access network. Injection of relays in a cell opens many issues of ... -
Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
Ahmed I.; Mohamed A. ( IEEE , 2011 , Conference Paper)We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ... -
Performance analysis for truncated ARQ based DSFBC-CO-OFDM communication scheme
Ahmed I.; Aljahdali S.; Hundewale N.; Mohamed A.; Shah S.I. ( IEEE , 2011 , Conference Paper)We develop and analyze an ARQ (Automatic Repeat reQuest) based distributed space-frequency block code-orthogonal frequency division multiplexing protocol for cooperative communications (DSFBC-CO-OFDM). At PHY layer, space ... -
Power control and group proportional fairness for frequency domain resource allocation in L-SC-FDMA based LTE uplink
Ahmed I.; Mohamed A. ( Kluwer Academic Publishers , 2015 , Article)Resource allocation in Long Term Evaluation (LTE) uplink is challenging because of two reasons: (1) it requires contiguous resource block allocation and (2) high complexity due to per user based power allocation among ... -
