DCAR: Distributed Coding-Aware Routing in Wireless Networks

The practical network coding system proposed in has two fundamental limitations like the coding opportunity is crucially dependent on the established routes; the coding structure is limited within a two-hop region. To overcome these limitations, Authors propose DCAR, the first distributed coding-aware routing mechanism which combines the discovery for available paths between a given source and destination, and the detection for potential network coding opportunities. DCAR has the potential to find high throughput paths with coding opportunities while conventional routing fails to do so. In addition, DCAR can detect coding opportunities on the entire path, thus eliminating the "two-hop" coding limitation in.
