Università degli Studi di Genova F-MAN Project – Final Review Genoa, December 2 nd – 3 rd, 2004 EDC HUB statistics Data relevance, SMS latencies, Power Consumption, Costs

Final Review Genoa, December 2 nd - 3 rd, Architecture overview SMS PDU (binary messages) … Archiving, logging, PARSING (Bin. XML) SMTP ( ) XML

Final Review Genoa, December 2 nd - 3 rd, Data relevance messages handled ( – ) Extracted data:  Host time (UTC)  reception of the SMS by the HUB.  OBT ID  OBT generation time (TX time - UTC)  time the OBT did send the SMS.  “User” (PI, SNCF, CP)  Message type (0x80, 0x82, 0x84, 0x90 …)  Power consumption  Position time  Event time (cfr. Excel file “all.xls”)

Final Review Genoa, December 2 nd - 3 rd, Message latencies (1) Host time (reception) – OBT generations time (send) Restrictions:  Only (“single” record 0x84 messages);  Valid Position & Event times;  For PI OBT’s only (differences between CP, PI and SNCF OBT’s prove to be not significant);  2850 records are useable data AVERAGE LATENCY: 2496 seconds (42 minutes) MEDIAN LATENCY: 63 seconds (cfr. All_d.xls)

Final Review Genoa, December 2 nd - 3 rd, Message latencies (2)

Final Review Genoa, December 2 nd - 3 rd, Energy consumption (1) Calculation base:  Host time, OBT ID, energy consumption;  Battery capacity: PwrCpt maximum value = 4651;  Result per OBT;  PI & SNCF OBT’s;  Different setup (messages per day) for PI and SNCF;  Worst Case scenario calculations

Final Review Genoa, December 2 nd - 3 rd, Energy consumption (2) SNCF Based on data in “sncf_power.xls”  Maximum energy consumption per month = 85 units (approximately 1.83 %);  Average power units used = 500;  Energy units remaining: 4651 – 500 = 4151 Months before alarm: 4151/85 = 48 months  (november 2008)

Final Review Genoa, December 2 nd - 3 rd, SNCF energy consumption percentage graph

Final Review Genoa, December 2 nd - 3 rd, Energy Consumption (3) PI Based on data in “pi_power.xls”  Maximum energy consumption per month = 208 units (4.5 %);  Average power units used = 1000;  Power units remaining: 4651 – 1000 = 3651 Months before alarm: 3651/208 = 17 months  (March/April 2006)

Final Review Genoa, December 2 nd - 3 rd, PI energy consumption percentage graph

Final Review Genoa, December 2 nd - 3 rd, SMS cost estimate Calculation base (cfr. FMAN_SIM_sept.xls)  Mobistar billing details from May -> September 2004;  Total number of SMS messages PI: 4031;  Total number of SMS messages SNCF: 3589;  No billing data for CP available; CP does not use “EDC” SIM cards. SMS cost PI: € 0.36 SMS cost SNCF: € 0.35 Fixed fee for CP SIM cards: € 0.02  0.05
