TDMA Multi-hop Wireless Network using Dynamic Subcarrier Control
Takeo Fujii (UEC) AN2008-18
Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a dynamic subcarrier utilization method using OFDM among the surrounding multi-hop nodes for improving the bottleneck node caused by unequal link quality of the flow from the source node to the destination node in TDMA multi-hop wireless networks. Although the flexible network can be realized by using multi-hop wireless networks, it has a hidden terminal problem occurred between the links in the self flow and degrades the end-to-end throughput performance of multi-hop wireless networks. As one of the solution of the hidden terminal problem, a TDMA multi-hop wireless network is considered. In TDMA multi-hop wireless network, the transmitting timing can be controlled not to give the interference toward the other links of the self flow. However, the data rate from the source node to the destination node of a fixed TDMA frame size is limited by the lowest quality link with small transmittable bits. As a result, the performance improvement due to avoiding interference degrades. Therefore, in this paper, we propose a dynamic subcarrier assignment method to reduce the effect of bottleneck link of TDMA wireless multi-hop networks.
