Towards a Distributed Quality of Service Handler for Multimedia Presentations
(
OMICS International
, 2013 , Article)
Distributed multimedia presentation, involving different media objects on different servers, must strictly follow its defined temporal scenario. Out of synchronization is a fundamental problem in case of distributed ...
Performance analysis of data intensive cloud systems based on data management and replication: a survey
(
Springer New York LLC
, 2016 , Article)
As we delve deeper into the ‘Digital Age’, we witness an explosive growth in the volume, velocity, and variety of the data available on the Internet. For example, in 2012 about 2.5 quintillion bytes of data was created on ...
Qualitative economic model for long-term IaaS composition
(
Springer Verlag
, 2016 , Conference Paper)
We propose a new qualitative economic model based optimization approach to compose an optimal set of infrastructure service requests over a long-term period. The economic model is represented as a temporal CP-Net to capture ...
Hierarchical security paradigm for iot multiaccess edge computing
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
The rise in embedded and IoT device usage comes with an increase in LTE usage as well. About 70% of an estimated 18 billion IoT devices will be using cellular LTE networks for efficient connections. This introduces several ...
Rational Contracts: Data-driven Service Provisioning in Blockchain-powered Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
Smart Contracts (SCs), which are software programs that run on blockchain platforms, provide appealing security guarantees characterized by decentralized, autonomous, and verifiable execution. On the other hand, Service ...
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 ...
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 ...
Effective capacity of cognitive radio links: Accessing primary feedback erroneously
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
We study the performance of a cognitive system modeled by one secondary and one primary link and operating under statistical quality of service (QoS) delay constraints. We analyze the effective capacity (EC) to quantify ...
On Designing Smart Agents for Service Provisioning in Blockchain-powered Systems
(
IEEE Computer Society
, 2021 , Article)
Service provisioning systems assign users to service providers according to allocation criteria that strike an optimal trade-off between users Quality of Experience (QoE) and the operation cost endured by providers. These ...
Optimal resource allocation for green and clustered video sensor networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
Wireless video sensor networks (WVSNs) are opening the door for many applications, such as industrial surveillance, environmental tracking, border security, and infrastructure health monitoring. In WVSN, energy conservation ...
