, 2015 , Conference Paper)
This paper presents the design, implementation and evaluation of ScalNet, novel network architecture for data centers. ScalNet is a cost-effective, high- performance and scalable interconnect with almost flat architecture. ...
Sparsity-cognizant multiple-access schemes for large wireless networks with node buffers
(
IEEE
, 2015 , Conference Paper)
This paper proposes efficient multiple-access schemes for large wireless networks based on the transmitters' buffer state information and their transceivers' duplex transmission capability. First, we investigate the case ...

Next-generation mobile networks will provide users with high data rates, increased mobility and various services. The initial step made in LTE and LTE-A is adopting the OFDM(A) air interface and utilization of dynamic ...
Sparsifying dictionary analysis for FIR MIMO channel-shortening equalizers
(
IEEE
, 2016 , Conference Paper)
In this paper, we propose a general framework that transforms the problems of designing sparse finite-impulse response channel-shortening equalizers and target impulse response filters for multiple antenna systems into the ...
Energy-efficient based on cluster selection and trust management in cooperative spectrum sensing
(
IEEE
, 2016 , Conference Paper)
Cooperative spectrum sensing (CSS) has been proposed as a solution for radio spectrum resources scarcity problem. Clustering technique is introduced to increase the performance of CSS and overcome the shadowing and fading ...

Cooperative access schemes for efficient SWIPT transmissions in cognitive radio networks
(
IEEE
, 2015 , Conference Paper)
We investigate joint information and energy cooperative schemes in a slotted-time cognitive radio network with a primary transmitter-receiver pair and a set of secondary transmitter-receiver pairs. The primary transmitter ...
Exploiting sparsity of relay-assisted cognitive radio networks
(
IEEE
, 2015 , Conference Paper)
We propose a novel protocol for secondary users based on compressive sensing principles. The secondary user assigned to one of the primary frequency bands is aided by a set of nearby secondary users, which we refer to as ...
A threshold-based opportunistic MAC protocol for MIMO wireless sensor networks
(
IEEE
, 2012 , Conference Paper)
In this paper, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
