Accelerate MapReduce’s Failure Recovery through Timely Detection and Work-conserving Logging

Fu, Huansong (2015-09-08)

MapReduce has become an indispensable part of the increasing market for big data analytics. As the representative implementation of MapReduce, Hadoop/YARN strives to provide outstanding performance in terms of job turnaround ...

Adaptation Service Framework for Wireless Sensor Networks with Balanced Energy Aggregation

Kim, Eun (2006-05-15)

Wireless sensor networks consist of tiny, energy-constrained sensor nodes that may be deployed in large numbers. Considering these unique characteristics, our adaptation service framework is designed to deliver distributed ...

Adaptive Connectivity Aware Routing Protocol for Wireless Vehicular Networks

Yang, Qing (2011-05-05)

Multi-hop vehicle-to-vehicle communication is useful for supporting many vehicular applications that provide drivers with safety and convenience. Developing multi-hop communication in vehicular ad hoc networks (VANETs) is ...

Boosting Cloud Computing Frameworks with High Performance Computing Features

Ramsey, Jared (2016-10-26)

High Performance Computing (HPC) often employs a set of networked and/or distributed computers working together to solve extremely large problems. Since the early 1990's, HPC has made use of technologies such as the Message ...

Congestion Control in Wireless Sensor Networks

Kulkarni, Anand (2010-07-30)

For this thesis we consider Directed Diffusion routing protocol. It manages paths in a data-centric way. A sink node publicizes its interest in some events. Such an interest will be disseminated within the network and ...

Continuous TCP Connection to the Internet on Fast-changing Mobile Ad-hoc Network

Lan, Tianhang (2019-05-01)

As more and more sensors are being used in all industries, especially the Internet of Things, Mobile Ad-hoc Networks (MANET) are also becoming more popular as good ways to organize wireless devices in the same area. Since ...

Cooling Hadoop: Temperature Aware Schedulers in Data Centers

Kulkarni, Sanjay (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 ...

Database Indexing for Skyline Computation, Hierarchical Relational Database, and Spatially-Aware SPARQL Evaluation Engine
