Stability and delay analysis for cooperative relaying with multi-access transmission
(
Springer Verlag
, 2015 , Conference Paper)
We consider a cooperative relaying system with two source terminals, one full duplex relay, and a common destination. Each terminal has a local traffic queue while the relay has two relaying queues to store the relayed ...
Detection of temporally correlated primary user signal with multiple antennas
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we address the problem of multiple antenna spectrum sensing in cognitive radios (CRs) when the samples of the primary user (PU) signal as well as samples of noise are assumed to be temporally correlated. We ...
Optimization of collaborative spectrum sensing with limited time resource
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, Cognitive Radios (CRs) collaborate in spectrum sensing to detect random signals corrupted by Gaussian noise. Our analysis is based on a limited time resource assumption. This implies that the time resource ...
Joint interference cancellation and dirty paper coding for cognitive cellular networks
(2011 , Conference Paper)
Downlink communication in a cellular network with a cognitive (secondary) cell is considered. In our model, the base station of the cognitive cell knows the messages of the other cell non-causally. We propose a new ...
On the synergistic benefits of alternating CSIT for X channel within a four-symbol channel extension
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we investigate the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). Three cases are considered for ...
All-to-all throughput maximization in wireless relay networks with multiple packet reception
(2012 , Conference Paper)
Network Coding (NC) has shown the promise of significant throughput improvement to wireless networks. Meanwhile, Multiple Packet Reception (MPR) has been proved as an efficient way to combat the Multiple Access Interference ...
EM-MAC: An energy-aware multi-channel MAC protocol for multi-hop wireless networks
(2012 , Conference Paper)
We propose an energy-aware MAC protocol, referred to as EM-MAC, for multi-hop wireless networks with multi-channel access capabilities. EM-MAC relies on iMAC's efficient channel selection mechanism to resolve the medium ...
Handoff-aware cross-layer assisted multi-path TCP for proactive congestion control in mobile heterogeneous wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Multi-Path TCP (MPTCP) is a new evolution of TCP that enables a single MPTCP connection to use multiple TCP subflows transparently to applications. Each subflow runs independently allowing the connection to be maintained ...
