On crowdsensed data acquisition using multi-dimensional point processes

Saket Sathe, Timos Sellis, Karl Aberer
2015 2015 31st IEEE International Conference on Data Engineering Workshops  
In this paper we propose using multi-dimensional point processes (MDPPs), a mathematical modeling tool that can be effectively used for performing this data acquisition task.  ...  Unlike traditional sensor network data, crowdsensed data has a highly skewed spatio-temporal distribution caused largely due to the mobility of sensors [1].  ...  Before we define multi-dimensional point processes (MDPPs) and discuss how they can be used for acquiring crowdsensed streams, we present two running examples that will be used throughout the paper.  ...
