Rate maximization for wireless ad hoc networks

We propose in this paper the centralized and distributed algorithms for rate maximization in wireless ad hoc networks with cochannel interference. The goal of the proposed algorithms is maximizing the data rate while minimizing the transmitting power on each hop. The distributed algorithm simulates the operation of the centralized algorithm in a distributed fashion and need not measure the link gains for all transmission links and interference links. We show that the distributed algorithm can find the maximal transmitting rate and the minimal transmitting power as the centralized algorithm does. Simulation results also show that the proposed distributed algorithm outperforms the previous distributed algorithm in the data rate achieved.
