The single-hop star-of-stars topology in low-power and wide-area networks (LPWAN) exhibits reliability and substandard coverage issues, especially in urban areas where line-of-sight (LoS) communication is difficult to achieve. Moreover, LPWAN trade-off the data rate to achieve longer coverage, preventing other end-devices from using the time resource. Locating other gateways is uneconomical as it requires infrastructure, […]

The single-hop star-of-stars topology of current Low Power Wide Area Network (LPWAN) is simple and robust but still lack of network coverage because of signal attenuation. We present a forwarding mechanism to increase the coverage and re-liability of LPWAN. Two key characteristics of our approach are on-demand and opportunistic forwarding. While most previous studies adopt […]
