Mobility, in its various forms, is one of the sources of several technical challenges being addressed in the last years to achieve a more flexible computing and communication infrastructure. In this context, the study and characterization of node mobility in wireless networks is extremely important to foresee the node distribution in the network, thus(More)
The study and characterization of node mobility in wireless networks is extremely important to foresee the node distribution in the network, enabling the creation of suitable models, and thus a more accurate prediction of performance and dependability levels. In this paper we adopt a structured Markovian formalism, namely SAN (Stochastic Automata Networks),(More)
Routing in Delay Tolerant Networks (DTNs) is an aspect of current research. In this kind of network disconnections are frequent and nodes have limited resources, making the design of new routing strategies a challenging task. In previous work we have proposed APRP (Adaptive Potential Routing Protocol) and compared with existing protocols. APRP uses the(More)
