Abstract
This paper introduces the Shadow, a decentralised
data-sharing model for mobile networks, and provides
insight into challenges faced in mobile replication and
communication technologies. Furthermore, the viability of
the implemented data-sharing model is evaluated and the
results explained. The Shadow has been designed to offer
maximum availability for data access while sacrificing
part of reliability. This paper shows that a combination
of optimistic replication and decentralised replica
management can be used to form highly adaptive data
sharing features for dynamic networks. The designed model
cannot be compared to database solutions, as it does not
provide strong consistency guarantees. On the other hand,
it functions without any manual preconfiguration and
centralised service providers. The Shadow provides high
data access availability and adaptability into the
environment at the expense of low reliability for data
semantics. It proves that mobile data sharing is viable
with current technology if update transactions are not
allowed.
