Routing in user-centric networks

This article considers the routing issues for user-centric network applications. User-centric network routing is a challenging problem because there may not always exist a complete stable path from an information source to its destination. In this article, we provide a brief overview on the state-of-the-art user-centric network routing schemes and discuss their performance in terms of data delivery ratio and delivery latency. We also present a few open research issues that are critical to user-centric network applications.
