No Wireless Networks Available in Windows 7?

Master — Fri, 04 Nov 2011 12:16:03 +0000

One problem I have run into on several Windows 7 machines is not getting any wireless networks when I go to the wireless network manager! Usually, when you click on Network icon in the task bar, you get a list of wireless networks and then just connect. However, there are times when you will see Post from: No Wireless Networks Available in Windows 7?

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

For the most part, wireless routers are a very simple networking component that you “set and forget.” However, initial setup and customization of a router, and setting up advanced features periodically are something that many wireless routers aren’t so good at, out of the box. This is one of the reasons that wireless routers tend Post from: Use DD-WRT to Hack a Wireless Router with Better Firmware

In the digital world, almost all of us make time to answer our email, but many of us think we do not have time to finish a book. Having Kindle apps installed on all our mobile devices helps, but there are still times when we are just too busy to read a book. Dripread exists to inspire us to read books by breaking hundreds of pages of text into small, 5-minute segments we can read from our email each day.

Deploying Power-Aware, Wireless Sensor Agents

admin — Fri, 25 Feb 2011 16:10:48 +0000

Developing sensor agents that can be deployed untethered in the field presents significant challenges in adapting to hardware, communication, power and environmental limitations. Real-world characteristics dictate agent behavior and operating strategies, sometimes quite differently from often held assumptions and intuitions. In this article, we describe the sensor-agent hardware and blackboard-system software used in CNAS (collaborative network for atmospheric sensing), an agent-based, power-aware sensor network for ground-level atmospheric monitoring

Localization Algorithms for Wireless Sensor Retrieval

admin — Thu, 02 Dec 2010 16:15:06 +0000

In wireless sensor networks (WSNs), localization has many important applications, among which wireless sensor retrieval bears special importance for cost saving, data analysis and security purposes. Localization for sensor retrieval is especially challenging due to the fact that the number and locations of these sensors are both unknown. In this paper, we propose two probabilistic localization algorithms that iteratively identify the locations of multiple wireless sensors in WSNs, one of which calculates location information offline, and the other online

Synchronizing your Blackberry

Without your existing contacts, tasks, calendar, and email, your Blackberry is little more than the average cell phone. Managing all of these items from the Blackberry itself can be arduous, and you have to keep your information from your computer in sync with the changes you make from the Blackberry. Synchronizing your data between your Blackberry, your computer, and the cloud, is easier than you think

Strengthen and Extend Your Home WiFi Signal

admin — Mon, 19 Jul 2010 11:29:16 +0000

Urban dwellers have an advantage over their rural counterparts when it comes to setting up a home wireless network. With smaller homes and apartments in the urban environment, the WiFi signal does not need to travel far. An entire urban home (of standard size—we have seen very large urban homes, too) can have WiFi connection with a single, well-placed router

E-book readers have gained popularity lately, largely due to a brewing price war that has carried through the three major manufacturers: Amazon, Sony and Barnes and Noble. While the Amazon Kindle is the most publicized of the e-readers, there are many features offered by the Sony Reader and Barnes and Noble Nook that the Kindle simply lacks. 1

Due to the increasing popularity of mobile Internet and location-enabled mobile devices in recent years, a new type of communication network is emerging, and we call it Near-me Area Network (NAN). It focuses on the communication among the wireless devices in close proximity, creating a new kind of application domain. In this article, we will introduce NAN, review the existing applications, and most importantly point out the challenges for the NAN applications
