    Strata: A simple lightweight ad hoc communications infrastructure
    (2005) Post, Ansley B.; Druschel, Peter
    This thesis presents Strata, a lightweight scalable implementation of the Safari architecture. Safari is an ad hoc network architecture, providing scalability to tens of thousands of nodes, integration of existing infrastructure, and self-organizing, decentralized network services. The Safari architecture is based on a self-organizing hierarchy that recursively partitions the network and assigns coordinates to nodes. Strata leverages the Safari structure to efficiently provide routing between two network hosts. As part of Strata's development, we developed a scalable, extensible network simulation environment that enables simulation of very large networks. The simulator's extensibility allowed us to explore the design space, revisiting many of the design decisions in the original Safari prototype. Early simulation results indicate that Strata can scale to several thousand fully mobile nodes with acceptable overhead.
