要約(日本語): In wireless multihop transmission, contentions and collisions among intermediate mobile computers in a transmission route reduce end-to-end throughput. In RH2SWL, due to controlled wireless signal transmission power and configuration of a multihop transmission route with hop-by-hop shortening links, it is realized to avoid the hidden terminal problem and to achieve higher end-to-end throughput. In order to guarantee higher reliable communication, hop-by-hop acknowledgment is introduced in most of wireless LAN protocols. This paper evaluates the performance of RH2SWL with a wireless LAN protocol with receipt acknowledgment. The simulation results show that the smaller an acknowledgment message is, the higher throughput is achieved.
