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 raises 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 paper 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, which maintain a vigil on the state of these mobile hosts to
provide higher quorum availability and ultimately higher data accessibility, better integrity and
