The capacity of wireless ad-hoc network is enhanced with rate adaptive algorithms. For rate adaptation, feedback of channel condition is essential. One of the ways to achieve this is the Cross-Layer Design (CLD) approach. The key idea is to exploit the channel condition by optimal selection of data rate. The data rate can be decided at transmitter or receiver to achieve the goal of capacity enh...
