UNB research on the Sensor Web project focusses on the
software and communication architecture for web sensor networks.
We aim to keep a light footprint for software
deployed on sensor networks while
maintaining robust and reliable operation.
Documents and pictures describing our research further
are listed below.
-
A link to the Sensor Web Language (SWL) wiki is
here.

A picture of the UNB Computer Science data communications lab setup
is
here. The picture was
taken Feb. 26, 2007. The base station and development workstations
are in the background. A tower with attached bridge sensor
camera is shown in the lab in
this picture.
-
A picture of an operational gateway node and sensor node operating
in the greenhouse of the UNB Forestry and Environmental Management
building
is
here. The picture was
taken Feb. 26, 2007. The large grey box is the gateway node, and is
connected to the larger (80W) solar panel. The smaller grey box in
the foreground is a sensor node connected to the smaller 5W solar panel and
four sensors (two air temperature, two solar radiation). Inside the gateway
control box looks like this (picture
taken June 14, 2007).

Burton Bridge pier pictures taken
Apr. 17, 2008, morning,
Apr. 17, 2008, late afternoon,
Oct. 19, 2007 at 15:39 and
Jan. 9, 2008 at 17:54
taken by the Stardot
Netcam sitting on top of the tower.
Sept. 13, 2007 picture of Burton tower with solar panel and
camera is here. Pictures of the
Burton Bridge
tower installation (taken June 11, 2007): the view from further up the bank,
a closer view of the tower and
base.
A picture taken (April 24, 2007) from the Burton Bridge tower location
is here. Note the high water.

Pictures of the intalled pier marker on Princess Margaret Bridge pier
taken
Apr. 17, 2008, late afternoon,
Nov. 10, 2007 at 14:53,
Nov. 21, 2007 at 15:06,
Nov. 22, 2007 at 01:04,
Jan. 10, 2008 at 15:32, and
Jan. 10, 2008 at 21:32.
A
gallery of images, one every two hours, shows what the
camera sees. On Nov. 29, 2007, the camera lens was changed, but
not properly focussed. On Jan. 9, 2008, the camera was focussed.
Dec. 14, 2007 pictures of the tower,
solar panel and camera, and
water level pier marker. The
pier marker "sign" is made in 3 sections. The top two are nominally
one metre high. The bottom one is nominally 1.1 m high. Each
horizontal "stripe" is 10 cm high. The long horizontal marks
are nominally 70 cm wide; the shorter horizontal marks are
nominally 50 cm wide starting at the leftmost edge of the pier
marker.
Sept. 13, 2007 picture of the Princess Margaret tower installation
(with solar panel + electronics) is here.
The view from further up the bank, and
a closer view of the tower and base.
Pictures
were taken June 5, 2007. On April 24, 2007,
this picture with high water was taken.

Nov. 29, 2007 pictures of the Lakeville Corner Bridge site:
view of the box from the front;
view of the box from the back;
close-up of the box from the front;
view from inside the box;
view from the opposite bank looking back towards
the box location.

A picture of the bog site in the UNB woodlot where the
An Adaptive Programming Model for Environmental Sensor Networks Using Fuzzy Logicsensor network is now deployed is
here. The picture was
taken Sept. 14, 2004. The gateway node is in the foreground,
and the water level sensor node is barely visible by John-Paul's
right shoulder.
