Mobile data is generated from a number of wireless sensing
and GPS enabled devices, regnant are mobile phones.
One of the fastest evolving data generating from these
mobile devices is Call data. Besides being spatio-temporal
in nature this data arrives continuously at high speed and
volume proportional to the number of devices. Batch processing
such data requires high cost in data warehousing
etc. Furthermore, the results may get antiquated. Stream
processing ceaselessly manipulates high speed data, while
maintaining the latest results. Ergo, we consider streaming
processing is an exemplary way of processing high velocity
data. It is one of the major challenges of data mining
community to learn from changing and evolving nature of
high velocity streams in real-time. Therefore, processing
streams typically require real-time incremental analytical
methods.
