LoRa is an unlicensed band-based low-power and wide-area (LPWA) technology, which has great network resource constraints because of its limited available frequency resource due to narrow industrial scientific medical (ISM) band, long response time due to its low data rate and low resource utilization due to its primitive medium access control (MAC). This paper studies […]

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 […]
