Opportunistic Random Access in CSMA/CA-Based Wireless Networks
(2013-10-18)
IEEE 802.11 MAC based CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance) is the most widely used protocol in wireless networks. In CSMA/CA, every
node listens to the shared wireless medium and transmits ...
Performance Evaluation of Split Disk-Cache
(2013-03-29)
The performance gap between the processor and the memory speeds has been ever increasing. Whereas processor speeds have improved by 60% annually, secondary storage speed has only improved by 10% annually. Although there ...
A Case Study in Applying Agile Software Engineering Practices to Systems Engineering
(2013-02-01)
With the fast-paced nature of technology, the need to rapidly field systems has never been more important. Success does not just depend on well-defined requirements but also on the ability to respond to change during and ...
Secure File Assignment in Heterogeneous Distributed Systems
(2013-04-23)
There is a growing demand for large-scale distributed storage systems to support resource sharing and fault tolerance. Although heterogeneity issues of distributed systems have been widely investigated, little attention ...
Context-based file systems and spatial query applications
(2013-04-23)
This dissertation presents studies related to I/O techniques in data-intensive computation and advanced solutions of spatial queries. There is a lack of general mechanisms for integrating multiple file system techniques ...
Cooling Hadoop: Temperature Aware Schedulers in Data Centers
(2013-01-07)
The amount of unstructured data, also known as “Big Data” in Internet is growing every day. Because the Big data is unstructured, a large-scale distributed batch processing infrastructure like Hadoop is used instead of ...
Design and Implementation of Scalable and Efficient Programming Models for Fast Computation and Data Processing
(2013-05-14)
Despite the tremendous growth of computational power, scientific applications and business data analytics
continue to face many challenges such as programming productivity, application scalability, and efficiency. ...
A Methodology for Increasing the Dependability of Open Source Software Components
(2013-04-16)
With the increasing use of open source software components in real world systems, there has arisen a need for increasing the dependability of these components. The dependability of these components can be increased like ...
An Indoor Spatial Query Evaluation System based on RFID and Particle Filters
(2013-04-05)
People spend a significant amount of time in indoor spaces (e.g.,
office buildings, subway systems, etc.) in their daily lives.
Therefore, it is important to develop efficient indoor spatial
query algorithms for supporting ...
Object-Oriented Design Quality Adaptation: A System Dynamics Simulation
(2013-04-19)
Despite the increasing interest of the software engineering research community in assessing and improving quality at the early phases of the software development lifecycle such as the design phase, less attention is devoted ...
