Abstract :
A reduced-power-consumption wireless ad-hoc multi-hop network system, the dual-link system,is been developed, using the following two technologies: Dual-link communication, which handles two different frequency bands, achieves low-power data transmission through independent optimum settings of both operation periods and communication distances for each band. The selection of frequency bands and operation settings depends on both the data sizes and communication intervals defined for individual applications. This dual-link communication is applicable to various kinds of intermittent communications. A vine-tree network topology that offers low addressing-bit counts and results in low packet-error rates even in low transmission-power communications. Since the topology does not require a routing table for individual nodes, hardware complexity can be kept to a minimum.
