Abstract

Disruption tolerant networks (DTNs) differ from traditional networks due to their special characteristics such as frequent partitions, intermittent connectivity, and message delivery delay. This paper presents a new idea for the resource management of sparse disruption tolerant networks where the density of nodes is insufficient to support direct end-to-end communications. The idea combines an asynchronous approach, where nodes work on their own wake up schedules without synchronized clocks, with an on-demand scheme, where a low power radio (LPR) is used to search about contacts and a high power radio (HPR) undertakes the actual data transmission.
