On the predictability of link lifetimes in urban MANETs

Link lifetime prediction is occurs frequently in MANET routing protocols. For example, in assigning cache timeout values and route durations, routing protocols make implicit predictions of link lifetime. Some protocols even make explicit predictions. In this paper the predictability of residual link lifetimes is examined. This investigation is performed via simulations that make use of detailed models of urban areas. Propagation is modeled using beam-tracing.
