We have proposed DR-IoT (Diversified-Range/Disaster-Response IoT), a VHF-band wireless communication system using small radios compliant with IEEE~802.15.4, as an enabling technology for digital self-managed wireless networks used by multiple organizations to exchange disaster-related information. DR-IoT aims to construct a network flexibly according to the application, communication range, and number of devices by utilizing many channels with multiple quasi-narrow bandwidths ranging from 6.25~kHz to 400~kHz. We propose the design of a channel access control scheme based on IEEE~802.15.4 beacon-based networks to take advantage of the multiple bandwidths and multiple-channel setting and discuss the feasibility of the DR-IoT system based on field experiments in the VHF-High band (207.5~MHz--222~MHz). |
