Exploiting Context-Awareness to Enhance Source-Location Privacy in Wireless Sensor Networks

admin — Fri, 30 Sep 2011 14:09:53 +0000

The source-location privacy problem in Wireless Sensor Networks has been traditionally tackled by the creation of random routes for every packet transmitted from the source nodes to the base station. These schemes provide a considerable protection level at a high cost in terms of message delivery time and energy consumption. This overhead is due to the fact that the data routing process is done in a blind way, without knowledge about the location of the attacker

This can feel very creepy, even for those of us who understand exactly how the ads are generated. Google is giving Chrome users a way to opt-out of these often-invasive advertisements, not just on their search engine, but in ads scattered throughout millions of Web sites

Use the New Screenshot Feature in Word 2010

Master — Mon, 21 Feb 2011 12:31:33 +0000

By now a lot of people know that Microsoft added the screen capture feature, “Snipping Tool” to Windows Vista and then improved upon that with Windows 7; what many people may not know however, is that Microsoft also added a screen capturing feature to Word 2010, called, appropriately enough, Screenshot . But recognizing that there was little point in simply reproducing what the Snipping Tool does, Microsoft made the Screenshot feature in Word behave differently.

Save Documents Directly to Windows Live SkyDrive using MS Word 2010

admin — Wed, 16 Feb 2011 12:23:21 +0000

Microsoft has made a lot of noise of late about the benefits of moving to the “cloud,” but hasn’t really done much in the way of showing users just exactly how to do so. One of the ways is by using Windows Live SkyDrive, which in reality is nothing more than an online storage facility that Microsoft has made available for free to anyone who signs up for a Windows Live account; which is also free – see another post Windows Live SkyDrive – 500 MB of secure online storage from Microsoft . To save a document you’ve created in Word 2010 to the SkyDrive, use Word’s Backstage Area via File : Click on it to reveal the backstage area: Look down past the usual menu choices to where it says Save & Send ; when you click on that, you’ll get: Next, click on Save to Web.

A Bandwidth-Based Power-Aware Routing Protocol with Low Route Discovery Overhead in Mobile Ad hoc Networks

Master — Tue, 03 Aug 2010 15:59:27 +0000

In the design of power-aware on-demand routing protocols in mobile ad hoc networks, it must be taken into account that nodes may use a great amount of power to find the desired routing path during the path-discovery phase. In addition, in previous research on power-aware routing protocols, the path bandwidth was often not considered. In this paper, we tackle these issues by proposing a power-aware routing protocol with low route requests (LRR) to find a path with high path bandwidth
