| Research Abstract |
1. Laboratory radio LAN
QPSK communication system and reliable fast TNCs (Terminal Node Controllers) are developed. Data transfer experiments are performed at 154 kbps on 270 MHz. The packet length dependence of the throughput, a comparison with a wired link etc. are examined.
2. Raio mobile host protocol
A routing protocol including routing in a radio network as well as a gateway between radio and wired networks is proposed. This is based on a mobile host protocol, VIP (virtual IP).
3. Radio experiment on a mobile host protocol
An extention of VIP to be used by radio hosts has started using the laboratory radio LAN.
4. Experiment on TCP/IP over ham radio
This experiment on TCP/IP network over ham radio using the KA9Q software package and a news system is useful for students to understand the TCP/IP protocol and the operation of the radio network.
5. Personarization of information
The laboratory radio LAN and the extention of VIP could be important for the mobile computing by radio.
