Long-range wireless sensor networks with transmit-only nodes and software-defined receivers
Wireless Communications and Mobile Computing
Wireless sensor networks for environmental monitoring and agricultural applications often face long-range requirements at low bit-rates together with large numbers of nodes. This paper presents the design and test of a novel wireless sensor network that combines a large radio range with very low power consumption and cost. Our asymmetric sensor network uses ultralow-cost 40 MHz transmitters and a sensitive software defined radio receiver with multichannel capability.
