Hi everyone, Sorry to border but I am doing my MSc Project that to add functions to support relation storage in the flash. My current experiment environment is TinyOS 1.x and using Tossim to simulate the work. Here are my questions:
Q1. Does Tinyos 1.x supports writing to flash that supports relation storage and expressive query? For example: *if you want to know the sites at which current the temperature is greater than the average historical temperature you would do: ** Select rstream s.id, s.time, s.temp* * from sensors[now] s* * where s.temp > (select avg(h.temp) from history[now] h);* * The scan on history h would be exactly the same as in the query Select * from history; The avg(h.temp) and the > would be done by existing aggregation and select operators. * If it dose, it that the MatchBox-way? If not, does Tinyos 2 support? Q2. I am now using Tossim to simulate the experiment. Is there any way to show the storage structure in flash and output as a txt file so that I can further analyse it and write scan operation in terms of the structures? If not, to what extend Tossim can simulate the storage and show the file in flash in detail, and how? I would be very appreciated if anyone contacts me about the question. Looking forward to you favorite response. -- Cheers Li ZHAO
