Grenoble Informatics Laboratory (LIG) is one of the largest laboratories in Computer Science in France. It is structured as a Joint Research Center (French Unité Mixte de Recherche - UMR) founded by the following institutions: CNRS, Grenoble INP, Inria, and Grenoble Alps University. The mission within this opportunity will be carried out at the LIG laboratory. It is proposed and funded in the context of the ENEDIS industrial chair of excellence on smart grids in partnership with Grenoble INP. 

Description

Nowadays, data come in huge masses from various sources such as web data, IoT data, scientific data, etc. This data deluge, more commonly known as Big Data, have introduced unprecedented performance and scalability challenges to data management and processing systems. In many cases, data are characterized by two very important dimensions: (geographical) space and time. As a result, many analytics applications and algorithms rely on spatial and/or temporal data queries and computations. Over the years, spatio-temporal data querying have been studied extensively in the literature. However, most of the introduced techniques fail to scale with Big Data volumes, or to integrate efficiently with large-scale data processing infrastructures (such as Hadoop).

The subject of this project is research oriented.  Its goal is to design and build a scalable architecture to store, manage, and process spatio-temporal data. 
It will also contribute to provide a high performance and scalable query engine for spatio-temporal data. The architecture will rely on the Hadoop file system (HDFS) to store data. Additionally, a hybrid solution to combine a scalable and distributed query engine with efficient data indexing and partitioning approach that leverage spatio-temporal data characteristics will be introduced. This latter will aim at providing a fast access to data and fast computing while minimizing data transfer and enhancing data locality. The proposed architecture will be further validated and evaluated with the case of IoT data.  A use case that consists of querying collected and historical sensor data deployed nation-wide on the power grid in France will thereby used for this purpose.

The project will consist in the following steps: 
- Study of the state of the art (bibliographical references, latest technologies): spatio-temporal indexing, Big Data management systems, distributed data querying, etc.. 
- Getting familiar with systems and frameworks: Hadoop, Spark, apache drill, mongoDB, 
- General design specification
- Implementation 
- Experimental validation and evaluation (IoT data)
- Documentation
