Routing for Diverse Wireless Networks
The paper is motivated by a simple question: can the authors design a simple routing protocol that works well across diverse wireless network environments such as meshes, MANETs, and DTNs? They identify packet replication as a key structural difference between protocols designed for opposite ends of the connectivity spectrum, namely, DTNs and meshes. They develop a model to quantify under what conditions and by how much replication improves packet delays, and use these insights to drive the design of ReGain, a routing protocol that self-adapts replication to the extent of connectivity in network conditions. They implement ReGain and evaluate its performance through deployment over a mesh testbed and trace-driven evaluations on real network testbeds exhibiting diverse connectivity.
