A packet-relaying method in wireless sensor communications

This paper presents a packet-relay method of receiving sensor data of long-distance nodes with predefined bit-rate sensing. The proposed method is an enhancement of the IEEE802.15.4 standard in order to provide reliable and robust wireless sensor communications even when radio propagation environment is not sufficiently good. Elaborate field tests show that the relay method significantly reduces the packet error rate.
