Timer-based broadcasting for power-aware routing in power-controlled wireless ad hoc networks

Abstract

We propose a new cross-layer design method for minimizing the total consumed power in power-controlled wireless ad hoc networks. In contrast to previous research, we consider not only a power-aware routing algorithm, but also a MAC layer algorithm that is adequate to optimize its performance. Computer simulations show that the proposed scheme outperforms the conventional schemes with respect to the average total consumed power, while maintaining a similar average success rate. Moreover, the proposed scheme approximates the optimal solution calculated by CPLEX, and is scalable, since each node operates in a distributed manner.
