要約(日本語): Each node in a sensor network does not have enough amount of a communication buffer. Hence, due to temporary increase of amount of transmitted sensor data, communication buffers in intermediate nodes along a multihop message transmission route suffer overflow. Since an intermediate node does not forward sensor data to its next hop node in which a communication buffer overflows, multihop transmission delay gets longer. This paper proposes a novel method to reduce additional transmission delay by forwarding sensor data to a neighbor node which is not included in a multihop transmission route when a communication buffer in a next hop node overflows. A routing protocol and a data transmission protocol are designed and the performance of these protocols are evaluated.
