| Research Abstract |
First of all, the feasibility of data transmission over multi-hop wireless communications in 27/40MHz wireless bands was verified in the at-sea experiment. In this environment, transmission speed is extremely low, that is, 1,200bps. Then we developed a new broadcast scheme called DISCOUNT-SJ (distance and counter-based scheme with short jitter) in order to surely and quickly disseminate messages from land-station to vessels (esp. fishing boats) in such a narrow band environment. We also developed a transmission power control called EqPC (equalized power control) scheme to enhance throughput of unicast communications. Our simulation results show that are superior to the existing ones.
