This work focuses on a class of distributed storage systems whose content may evolve over time. Each component or node of the storage system is mobile and the set of all nodes forms a delay tolerant (ad hoc) network (DTN). The goal of the paper is to study efficient ways for distributing evolving files within DTNs and for managing dynamically their content. We specify to dynamic files where not only...
We study secondary spectrum sharing in narrowband cellular networks in which calls in neighboring cells need to be assigned different channels. Analysis of such networks are in general difficult due to large state spaces and lack of closed form expressions. Here we consider linear topologies and show that they lend themselves to exact analysis. We analyze four sharing policies where equilibrium distribution...
