An Improved Quorum Selection Algorithm

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 adopted 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 it? 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 stale of these mobile hosts to provide higher quorum availability and ultimately higher data accessibility, better integrity and consistency.
