Energy efficient antenna selection for a MIMO relay using RF energy harvesting
Samy, Islam; Butt, M. Majid; Mohamed, Amr; Guizani, Mohsen ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Energy harvesting has emerged as a promising technique which helps to increase the sustainability of wireless networks. In this paper, we consider a network with a single source, single destination and a single relay ... -
Maximizing energy efficiency for loss tolerant applications: The packet buffering case
Butt, M.Majid; Jorswieck, Eduard A.; Ottersten, Bjorn ( IEEE , 2013 , Conference Paper)Energy efficient communication has emerged as one of the key areas of research due to its impact on industry and environment. Any potential degree of freedom (DoF) available in the system should be exploited smartly to ... -
Maximizing Energy Efficiency in Multiple Access Channels by Exploiting Packet Dropping and Transmitter Buffering
Butt, M. Majid; Jorswieck, E.A.; Ottersten, B. ( IEEE , 2015 , Article)Quality of service (QoS) for a network is characterized in terms of various parameters specifying packet delay and loss tolerance requirements for the application. The unpredictable nature of the wireless channel demands ... -
On the power efficiency for cognitive radio networks with multiple relays
Ashour, Mahmoud; Butt, M. Majid; Mohamed, Amr ( IEEE , 2014 , Conference Paper)In this paper, we study and analyze cooperative cognitive radio networks with multiple secondary users (SUs). Each SU is considered a prospective relay for the primary user (PU) besides having its own data demand. The ... -
RF energy harvesting communications: Recent advances and research issues
Butt, M. Majid; Krikidis, Ioannis; Mohamed, Amr; Guizani, Mohsen ( Springer International Publishing , 2016 , Book chapter)Green radio communications has got a lot of attention in recent years due to its telling effects on telecom business and environment. On the other side, energy harvesting (EH) communication has emerged as a potential ... -
Trading wireless information and power transfer: Relay selection to minimize the outage probability
Butt, M. Majid; Nasir, Adnan; Mohamed, Amr; Guizani, Mohsen ( IEEE , 2014 , Conference Paper)This paper studies the outage probability minimization problem for a multiple relay network with energy harvesting constraints. The relays are hybrid nodes used for simultaneous wireless information and power transfer from ...
