Transcoding resources forecasting and reservation for crowdsourced live streaming
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
During the last decade, empowered by the technological advances of mobile devices and the revolution of wireless mobile network access, crowdsourced live streaming has become more popular. Ensuring a stable high-quality ...
Modeling and analysis of an infrastructure service request queue in multichannel V2I communications
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
This paper presents a concise yet comprehensive description of a multichannel vehicle-to-infrastructure communication system. Existing mathematical models for such a system overlook some of its essential behavioral ...
On the performance of advanced QoS-aware packet scheduling for multiantenna packet radio systems
(
IEEE
, 2010 , Conference Paper)
In this paper, we study and analyze the performance of advanced OFDM packet scheduling techniques with given QoS requirements under the 3GPP UTRAN Long Term Evolution (L TE) framework. Stemming from our previous studies ...
Priority-based zero-forcing in spectrum sharing cognitive systems
(
IEEE
, 2013 , Article)
We consider a spectrum sharing scenario between cognitive radio (CR) users and a licensed primary user (PU), in which the PU is not able to successfully transmit data to its destined receiver. The cognitive base station ...
Cooperative cognitive relaying under primary and secondary quality of service satisfaction
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper proposes a new cooperative protocol which involves cooperation between primary and secondary users. We consider a cognitive setting with one primary user (PU) and multIPle secondary users (SUs). The time resource ...
On the design of relay-assisted primary-secondary networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The use of N cognitive relays to assist primary and secondary transmissions in a time-slotted cognitive setting with one primary user (PU) and one secondary user (SU) is investigated. An overlapped spectrum sensing strategy ...
Exploring blind online scheduling for mobile cloud multimedia services
(2013 , Article)
Mobile cloud is a new emerging technology which can be used to enable users to enjoy abundant multimedia applications in a pervasive computing environment. Therefore, the scheduling of massive multimedia flows with ...
Millimeter-wave multimedia communications: Challenges, methodology, and applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
The worldwide opening of a massive amount of unlicensed millimeter-wave spectrum has triggered great interest in developing high-bit-rate multimedia services and applications. Specific challenges for mmWave communication ...
MINTED: Multicast virtual network embedding in cloud data centers with delay constraints
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Network virtualization is regarded as the pillar of cloud computing, enabling the multi-tenancy concept where multiple Virtual Networks (VNs) can cohabit the same substrate network. With network virtualization, the problem ...
QoS optimization for cloud service composition based on economic model
(
Springer Verlag
, 2015 , Conference Paper)
Cloud service composition is usually long term based and economically driven. Services in cloud computing can be categorized into two groups: Application services and Computing Services. Compositions in the application ...
