| Research Abstract |
This study showed that transmission priority control achieves optimal throughput performances of slotted ALOHA multi-hop wireless communication systems with network coding methods by computer simulations and theoretical analyses. Furthermore, computer simulations and theoretical analyses reveal the effects of thermal noise and radio interferences from other radio systems on the throughput performances of our systems. For home area multi-hop wireless networks, which are composed of the IEEE 802. 11 standard based wireless LANs, the throughput performances and delay performances are improved by the novel control schemes of CWmin and AIFSN. Moreover, these schemes enable the QoS control of VoIP(Voice over IP). Computer simulations show the good performances of the proposed QoS control scheme.
