In this paper we propose a distributed approachto construct vicinity resource maps at each node in a delay-tolerant network. The scheme uses recent encounters to estimatethe availability of the following resources: energy, buffer space,and bandwidth, in the vicinity of a given node. We then show howa store-carry-forward scheme may benefit from having accessto these resource estimates. While knowledge about resourcesavailable in the vicinity allows nodes to implement meaningfulcustodian election strategies, an evaluation of available band-width and contact time allows them to carry out adaptivequeue management strategies. Thus, such strategies can beapproached from a holistic perspective based on the availabilityof the three resources under consideration in node proximity. Wevalidate our model separately in time-varying and space-varyingenvironments. In addition to synthetic mobility models (randomwaypoint) we validate our resource estimation in a disasterarea mobility model (using Bonn motion traces). We show thatby using this information a routing protocol may dramaticallyimprove its delivery rate and reduce energy overhead whilekeeping delivery latency almost constant.
