An Examination of the Latencies Found in a Wi-SUN FAN Network

This paper reports on the results of multicast latency and round trip time measurements for a particular deployment of nodes forming a Wi-SUN FAN 1.0 network [1]. The authors have explored in detail the behaviour of the WiSUN FAN network used by Hee-Jun Lee and Sang-Hwa Chung, the authors of a prior paper, in order to provide more detail regarding the latencies and delays cited in that paper [2]. We provide details regarding: • the timing of the component requests and responses that comprise the Lee and Chung round-trip and latency measurements, and • additional timing and packet delivery ratio results for variations of the MPL retransmission parameters for the Wi-SUN FAN protocol used on the Lee and Chung test network [3].
