In this paper, we propose a distributed power control scheme which can take into account the end-to-end performance of users in a multihop cellular network. Bottleneck links in a multihop wireless network limit the maximum rate achieved by users along their routes. Under the proposed scheme a link dynamically switches between different power adaptation algorithms based on whether it is a bottleneck or a non-bottleneck link. Specifically, non-bottleneck links iteratively reduce their transmit powers whereas the bottleneck links use power control to exploit the corresponding interference reduction and further increase their signal-to-noise-and-interference ratios (SINRs). We show substantial system throughput performance gain under our scheme and for which, under certain scenarios, we derive a closed-form expression of the converged transmit power levels regardless of their initial values.
