Big data for C4i systems: goals, applications, challenges and tools

C4I (Command, Control, Communication, Computer and Intelligence) systems became the core of the command and control operations in military, emergency response, disaster management etc. The data sets used by these systems are large and complex to analyze and analysis process take long time. In today´s scenario the quantity of information or data that is traveling over the internet is not only huge in size but intricate as well. Big Data are now speedily growing in all domains of science and engineering due to fast expansion of data storage, networking and data collection capacity. Since Big Data is an emerging technology in the market which can bring huge benefits to the companies and organizations, it becomes a need of time to understand this technology. C4I systems can also be benefitted from Big Data. In this paper some important goals, applications, challenges and tools of Big Data are highlighted in context of C4I systems that will be helpful for both academia and industry to further strengthen the basis of Big Data usage in C4I systems.
