Location-centric data storage is a fundamental paradigm for data
management in wireless ad-hoc networks. It guarantees that data is
stored at network nodes near specific geometric reference locations
in the region where the network is deployed. In mobile ad-hoc
networks, maintaining spatial proximity between data and its
associated location requires explicit migration mechanisms in order
to "keep the data in place". In this paper we propose
comprehensive policies for data migration that effectively maintain
the spatial coherence of data given the particular characteristics
of mobile ad-hoc networks. Using extensive simulations we show how
the proposed policies outperform related migration approaches over a
wide range of system parameter settings, in particular, node
density, network dynamics, and migratable data size.
