In this paper, a novel routing algorithm for relay selection (RS) in multi-hop relay networks is proposed based on Viterbi algorithm with truncated decoding memory. It maps the network topology to a trellis diagram of a convolutional code. In the trellis, the branch metric is the inverse of the instantaneous SNR of the corresponding channel. Consequently, the path metric, which is the accumulated branch metrics along the path, is equal to the inverse of the equivalent SNR of the path… CONTINUE READING
