Cross-Layer Optimal Policies for Spatial Diversity Relaying in Mobile Ad Hoc Networks
In order to adapt to time-varying wireless channels, various channel-adaptive schemes have been proposed to exploit inherent spatial diversity in mobile/wireless ad hoc networks w...

A Tone Dual-Channel DMAC Protocol in Location Unaware Ad Hoc Networks
- Directional antennas are used to improve spatial reuse, but have the problem of deafness. The DUDMAC protocol [9] uses the ORTS, OCTS, DDATA, and DACK mechanisms and a blocking a...
