Re: [Tinyos-help] Telosb image processing

[rupesh vishwakarma]

Thanks for reply
the problem is that if I use Block Read interface I will not be able to  track 
the seek position in the image thats why I read 3 bytes at a time I use 

logread interface for the same.

Well...The MSP chip doesn't have a Multiply instruction (I'm a little
surprised because the ATMEGA does and I never bothered to look).
But it does do 16 bit integer Add and Sub so that's something...
Therefore you need to be very careful with your math, and possibly
hand-asm-code the inner loops.

Also access to the external EEPROM may be rather slow, you should
look into comparing the speed with the internal Flash memory for
your image storage. Probably transferring larger blocks of data
from ROM to RAM will help a bit too.

Re: [Tinyos-help] Sensing humans?

[Michael Schippling]

What you probably want is a PIR sensor (Passive InfraRed) like those
used in motion sensitive porch light fixtures. Here's one example:
http://www.sparkfun.com/products/8630

Note that they detect low-freq IR (around 10nm) which is what mammal
bodies radiate, and they need a differential signal from motion so
if you stand still (or wear a heavy parka) they may not fire.

Hello everybody!
I am using tinyOS -2.1.0 and telosb motes. I need to detect human presence,
so I wonder if there is something like an occupancy sensor.

[Tinyos-help] TestAck on Iris motes

[Sébastien DERONNE [530812]]

Dear Sir or Madam,

I want to test the acknowledgement process on my Iris motes.
I then programmed on two Iris motes the TestAck application available in 
tinyos-2.x/apps/tests/cc2420.

However, only the red light toggles, meaning that no frames are acknowledged.
Can you please help with this point?

Best regards,
Sébastien Deronne

[Tinyos-help] CTP updateRouteTask() behaivior if parent gets

[Christian]

Dear TinyOS community,

I have a problem understanding, how CTP's updateRouteTask() works, if
the 4-Bit Link Estimator is used.

Consider the following example:
Node 2 with costs 70 is currently using node 1 (costs 20) as parent.
He could also choose node 3, that has costs 60 over a link of costs 10.

(1:20)
  ^
  |
  |50
  |
(2:70) ---> (3:60)
  10

If I understand it correctly, when node 1 gets down, the costs of the
link to node 1 will reach the maximum value of DLQ_PKT_WINDOW * 10
= 50 (LinkEstimatorP.nc l. 296 in updateDETX()), because no acks can be
received from node 1 as well as no beacons, that could update beacon
based link etx.
The problem, that I see here, is, that the link's costs cannot get
worse than 50 (limited by DLQ_PKT_WINDOW) and that updateRouteTask()
would not change to node 3, because the path over node 3 is not
"significantly" (PARENT_SWITCH_THRESHOLD) better than the path over
node 1.
So it will stay with node 1 as parent even if node 1 isn't available
anymore.

Please explain: is this really the case or what do I miss out?

Just in case I'm right, one could solve this problem by requiring every
parent's link costs to be below DLQ_PKT_WINDOW*10 and changing to
another node in updateRouteTask(), if this is not the case.


Thanks,
Christian
