Executive Summary

DTNs have emerged as an attractive networking paradigm for mobile networks where transmission links among mobile nodes are dynamically established or torn down and communication is accomplished through multi-hop message relaying. Such environments are becoming increasingly prevalent due to the rapid growth of heterogeneous mobile devices and delay-insensitive applications. A key problem in DTNs is the selection of relay nodes. The problem is unique in DTNs because relays are not necessarily determined before the transmission of packets by the source.
