Abstract:
As communication becomes more and more an integral part of our
day to day lives, so our need to access information increases as
well. Mobility is currently one of the most important factors to
consider in our aim to achieve ubiquitous computing, and with it
rises the problem of how to manipulate data while maintaining
consistency and integrity. Recent years have seen tremendous
interest in quorum systems adapted to mobile hosts; however, the
more recent topic, of studying the effects of mobile networks on
quorum systems, has also been the focus of interest for building
quorums aware of their network surroundings. This thesis presents
a novel approach in selecting mobile hosts to form epidemic
quorum coteries, based on metrics measured by mobile hosts and
then transmitted to Base Station servers. The BS constantly
maintains a vigil on the state of these mobile hosts to provide
higher quorum availability and ultimately higher data accessibility,
better integrity and consistency.
