Abstract
The emergence of mobile P2P systems is largely due to the
evolution of mobile devices into powerful information
processing units. The relatively structured context that
results from the mapping of mobile patterns of behaviour
onto P2P models is however constrained by the
vulnerabilities of P2P networks and the inherent limitations
of mobile devices. Whilst the implementation of P2P
models gives rise to security and reliability issues, the
deployment of mobile devices is subject to efficiency
constraints. This paper presents the development and
deployment of a mobile P2P system based on distributed
hash tables (DHT). The secure, reliable and efficient
dispersal of files is taken as an application. Reliability was
addressed by providing two methods for file dispersal:
replication and erasure coding. Security constraints were
catered for by incorporating an authentication mechanism
and three encryption schemes. Lightweight versions of
various algorithms were selected in order to attend to
efficiency requirements.
