要約(日本語): In mobile wireless networks such as ad-hoc networks, sensor networks and mesh networks, wireless multihop transmission is adopted for data message transmission. For achieving higher throughput and shorter transmission delay, TDMA is one of more effective methods which avoid collisions and contentions than CSMA/CA and RTS/CTS. This paper proposes a reactive TDMA time slot assignment method in which time slot assignment gets active only when wireless multihop transmission is initiated. Here, a slot is assigned not to a mobile computer but to a wireless communication link included in an active wireless multihop transmission route for achieving higher connectivity due to less assigned TDMA time slots. This paper discusses restrictions of TDMA slot assignment and design slot assignment and release protocols.
