In order to analyze the average number of transmissions and retransmissions, and the handover latency, we use the packet loss rate by SNRs with f fragments of a CoAP message in [4]. It is assumed that wireless link bandwidth and wired link bandwidth are 250Kbps and 100 Mbps, respectively. The tDHCP, tMD, tL2, t(mCSN, ER), t(mCSN, IMMS), t(mCSN, CWC), t(CWC, IMMS), S, and m are set to 5000 ms, 100 ms, 50ms, 4.4 ms, 79.4 ms, 79.4 ms, 50ms, 113 byte, and 4, respectively.
