A comparative analysis of BLE and 6LoWPAN for U-HealthCare applications
(
IEEE
, 2013 , Conference Paper)
For decades, there exist a variety of low-power wireless technologies deployed for healthcare applications such as Zigbee/IEEE802.15.4, Bluetooth, ANT, NFC, IrDA. However, the recently announced Bluetooth Low Energy (BLE) ...
Performance analysis of M2M communication networks for QoS-differentiated smart grid applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
We study the performance of Machine-to-Machine (M2M) communications in Long Term Evolution Advanced (LTE-A) networks. The proposed analysis is applied to the random access procedure within LTE-A for the calculation of the ...
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 ...
Green operator cooperation for radio frequency transmission minimization
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
The increasing demand for reliable mobile services with faster communications speed requires high capital investment in the radio access networks. This leads to enormous energy consumption, high operational costs (OPEX), ...
Cooperative communications scheme with interference management under ICI for OFDM LTE-A systems
(
IEEE Computer Society
, 2013 , Conference Paper)
In long term evolution (LTE) systems, the achievable cell spectral efficiency is often limited by the inter carrier interference (ICI) or coverage shortage of base stations. Hence, in LTE-Advanced, cooperative communication ...
Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper ...
Analysis of cell spectral efficiency of infrastructure relay-enhanced cellular system
(
IEEE
, 2011 , Conference Paper)
In this paper, we investigate the downlink spectral efficiency of infrastructure relay-enhanced cellular systems. In particular, we use the average achieved spectral efficiency at an arbitrary mobile receiver in presence ...
Towards energy efficient relay placement and load balancing in future wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper presents an energy efficient relay deployment algorithm that determines the optimal location and number of relays for future wireless networks, including Long Term Evolution (LTE)-Advanced heterogeneous networks. ...
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 ...
Performance analysis of best relay selection scheme for amplify-and-forward cooperative networks in identical Nakagami-m channels
(
IEEE
, 2010 , Conference Paper)
In cooperative communication networks, the use of multiple relays between the source and the destination was proposed to increase the diversity gain. Since the source and all the relays must transmit on orthogonal channels, ...
