Superframe division multi-hop data collection with aggregation on Wi-SUN profile for ECHONET Lite

This paper proposes an effective multi-hop data collection scheme using a superframe division technique with frame aggregation on a Wi-SUN profile for ECHONET Lite. In the proposed scheme, a Wi-SUN MAC layer profile deploying IEEE 802.15.4/4e-compliant LE superframe-based multi-hop transmission mitigates the bottleneck problem by controlling the radio link numbers in a superframe, thereby preventing the data collection throughput degradation expected in high-traffic situations such as emergencies. Computer simulation results confirm that the proposed superframe division multi-hop data collection scheme with frame aggregation achieves over a 95% frame success probability under the high-traffic situation in which 1,000 meter nodes generate frames at a 10-minute interval.
