Wake-on-WLAN
In bridging the digital divide, two important criteria are cost-effectiveness, and power optimization. While 802.11 is cost-effective and is being used in several installations in the developing world, typical system configurations are not really power efficient. In this paper, we propose a novel “Wake-on-WLAN” mechanism for coarse-grained, on-demand power on/off of the networking equipment at a remote site. The novelty also lies in our implementation of a prototype system using low-power 802.15.4-based sensor motes. We describe the prototype, as well as its evaluation on field in a WiFi testbed. Preliminary estimates indicate that the proposed mechanism can save significant power in typical rural networking settings.

Its an extreemely helpful blog …
I am very new in the field of wsn and the links I got here are really cool. An effort definitely appreciable!
I have a question .. I’ve been looking at what I can work with for sometime now … is it possible to do something here without the sensor motes? Can I do something armed with a reasonably configured pc ..
I am seeing ns2 but is there any better option?
I have a siggestion … can you please host a web forum for excahnging informations … it would be really helpful for n00bs like me.

Hi there.
Sensor Networks is indeed a very exciting area of research today.
There are lots of resources in this site and in the web. We’d recommend you start with http://www.wikipedia.org then take a look at http://www.tinyos.net. Most of the work we are involved with is open source thus TinyOS like. If you want to play with some codes and simulator you should take a look at the Boomeran package at http://www.moteiv.com. The simulator is call TOSSIM. There you’ll certainly find some entertaiment even without having the motes’ harware, at least for a while.
good luck.
Claro.

just want to add that even if you dont have motes and you write your code in TOSSIM/TinyOS you can then send the code to remote test lab e.g. MistLab(MIT) and MoteLab (Harvard) and fetch the results.
