Abstract :
In this paper, we propose several joint rate adaptation and routing solutions for energy efficient communication in CDMA ad hoc networks. The proposed schemes exploit the interactions between layers, by jointly acting at the physical and the network layer to effectively manage the network interference. At the physical layer, an appropriate transmission rate is selected based on the current link quality. At the network layer, routes are determined such as to minimize the end to end energy consumption. To further improve the performance, a coding/spreading technique is used that gives an additional coding gain advantage.
