Delay-Tolerant Link-State Routing
This is my third-year dissertation project for the University of Cambridge Computer Science Tripos. The project is to evaluate and compare the performance of routing protocols LSR and DTLSR in a variety of network topologies and situations, to determine where delay-tolerant modifications improve or worsen performance. Both protocols are modelled off of standard OSPF, but implemented completely from scratch.
The protocols are evaluated on the Common Open Research Emulator (CORE), a network emulator released by the U.S Naval Research Laboratory (link).
LSR and DTLSR are routing protocols for running on network routers. They use a link-state representation of the network topology for routing. DTLSR is LSR with modifications that allow it to perform better in unreliable, variable-delay network conditions, making it delay-tolerant.
