Transition of delay and throughput in low traffic load Figures 10 a and 10 b show respectively the transition of IP average delay and IP throughput when file size in FTP is 1K bytes. As the packet distribution proceeds the IP average delay of the proposal decreases rapidly and becomes much lower than that of the Traffic Control for Composite Wireless Access Route of 16 Links 291 Simulation Time sec a Average delay.
