Self-Adaptive and Stateless Broadcast in Delay and Disruption Tolerant Networks

Free registration required

Executive Summary

In a delay and disruption tolerant network, or DTN, the network connectivity is intermittent, the radio links are poor and unstable, the nodes dynamically move and are sparsely distributed. These critical conditions have imposed a departure from the routing mechanisms viable in ad hoc networks and the adoption of a topology independent, store-carry and forward paradigm that allows the creation of an improvised path towards the destination(s) by exploiting the relay opportunity of nodes happening to be in the radio range as the effect of mobility.
