Abstract:
Inspired by the flocking behavior, we propose a distributed transmit power control (TPC) algorithm for maximizing the end-to-end rate in a linear multi-hop wireless network. As each bird in flock goes to match its velocity with the average velocity of its neighbors in a distributed manner, each node on the multi-hop path matches its transmission rate with the average transmission rate of its neighbor nodes by controlling its transmit power. We verify that this TPC algorithm performing a local rate-average strategy maximizes the end-to-end rate of the wireless multi-hop link. Simulation results show that as with the flocking algorithm, the proposed TPC algorithm enables all link rates to converge to the same value, and also significantly decreases the power consumption of multi-hop nodes, while maximizing the multi-hop end-to-end rate.
