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.

  1. A link to the Sensor Web Language (SWL) wiki is here.
  2. 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.
  3. 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).
  4. 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.
  5. 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.
  6. Lakeville Corner bridge camera pictures Apr. 17, 2008 around mid-day and Apr. 17, 2008 at around mid-morning. April 3, 2008 picture of the Lakeville Corner Bridge solar panel and antenna setup. Mar. 7, 2008 pictures of the Lakeville Corner Bridge site: view approaching the bridge from the south; view of the solar panel on top of the height warning beam; view of the box and conduit from the front; view of the pier marker from the box location; close-up view of the pier marker. 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.

  13. 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.
