Detecting appropriate Replication approach considering Client and Server parameters in mobile environment
Mobile technology is going to be one of the most useful and practical technologies over 21 century. Mobile devices with integrated databases or caches are so useful for most of applications. This new environment with mobile servers and clients has some special characteristics that vary it from traditional distributed systems. Because of these special properties, protocols which were designed for traditional systems are not suitable for mobile environments. Previous schemes are passive in nature and rarely consider these new characteristics. One of the most important and useful schemes especially in distributed databases is replication. Replication techniques are used to increase performance, availability, reliability and scalability of various types of distributed systems (e.g. p2p and data grid). But obviously they are not appropriate for this new environment with unique characteristics and dynamic features. It is better to design situation depended protocols with dynamic nature. In this paper we illustrate part of a framework that can mange replication strategy in various situations. For this mean values of most important properties for basic components of environment (e.g. mobile servers and clients) will be used to choose an appropriate strategy through multi criteria decision making approach.
