I am looking for research papers (conference/journals) on the topic of SWE (Sensor Web Enablement) and SOS (Sensor Observation Service) also dealing/including security aspects.
I have already found some sources (after cleaning up, will post them here too) but you could post any expert material or websources where to search.
If by "security aspects", you mean SWE/SOS as used in security systems, you might try googling "alternatives to incarceration gps".
Some might consider this a form of geoslavery. Coincidentally, a disproportionate number of the companies in this market, like GpsAim, seem to be based south of the Mason-Dixon line.
You can also find some papers from the previous SWE workshops in IEEEXplore.
You may want to check the publications related to "Geoshield": https://sites.google.com/site/geoshieldproject/home
