Relay control ought to be performed when a direct communication link cannot be established between the source station and the target station. We propose in this paper how such function can be accomplished effectively in Wireless 1394 based networks. Simulation results yield the fact that the proposed scheme not only can optimize the data relay control from the perspectives of the premium (the lowest cost) relay path and relay station selection but also can improve the system's performance in terms of its higher packet delivery ratio and lower packet end-to-end delay in a shadowing prone home environment.
