The problem of joint routing and power allocation optimization is addressed for decode-and-forward (DF) and amplify-and-forward (AF) multihop TDMA wireless networks. A distributed solution is proposed for power-optimized routing with desired end-to-end capacity constraint based on the local instantaneous channel state information measurement at the nodes of the network. The proposed distributed routing algorithm is optimal in DF networks and performs close to optimal in AF networks.
