A pragmatic node based DTN performance modeling

Unlike traditional mobile networks, the store, carry, and forward paradigm of DTN architecture, enables a resource hungry DTN node (such as mobile phone) to carry the messages until it physically meets the destination node or a potential relay node. The storage and communication of the node are precious resources that play a vital role in the DTN routing. The state-of-the-art DTN research, models the node as a monolithic storage structure with the single communication antenna for data transfer. However, the practical bi-level hierarchical storage structure and the latest wireless technologies such as MIMO in the mobile phones, exemplify the oversimplified nature of the existing node abstraction. To this end, my PhD research focuses on the DTN performance modeling with a pragmatic node abstraction.
