Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)This paper studies fundamental throughput and delay tradeoffs in cognitive radio systems with cooperative secondary users. We focus on randomized cooperative policies, whereby the secondary user (SU) serves either its own ... -
Lineament Analysis Of Qatar Peninsula Based On Landsat Imagery
( Qatar University , 1990 , Article)Photo-interpretation of Landsat MSS images of Qatar Peninsula reveals several surface lineaments of different types, extentions and trends. Some of these photo-lineaments are of structural nature while others represent ... -
On spectrum sharing between energy harvesting cognitive radio users and primary users
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ... -
Optimal spectrum access for a rechargeable cognitive radio user based on energy buffer state
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ... -
Power-optimal feedback-based random spectrum access for an energy harvesting cognitive user
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we study and analyze cognitive radio networks in which secondary users (SUs) are equipped with energy harvesting (EH) capability. We design a random spectrum sensing and access protocol for the SU that ...
