Cognitive Radio - When IoT Gets Intelligent

Spectrum is becoming scarce. Trillions of devices are expected to be wirelessly connected.
Quality of service is the name of the game. Reliability and scalability remained a big issue.

Concept of Shadow Network

The concept of “Shadow Network” was first developed by Dr. Mazlan Abbas and his team from MIMOS on June 18, 2011.
Its the future of Ubiquitous Network which is very flexible that can form and adapts to its surrounding environment.

RFID (Radio Frequency Identification) is a tagging technology that is gaining widespread attention due to the great number of advantages that it offers compared to the current tagging technologies being used today; like barcodes. Near Field Communication, or more commonly known as NFC, is a subset of RFID that limits the range of communication to within 10 centimeters or 4 inches.
RFID uses radio frequency waves that are either passive, active, or a combination of both. Active RFID tags have a power source that helps extend their range even further while passive devices rely on the energy that it receives from the interrogating device to send its own information. Among the advantages of RFID is the very small size of the tag that made it possible to be used with small products or to be hidden away neatly. Another excellent advantage is that it doesn’t need a direct line of sight for the information to be read. This is very desirable in baggage tracking application where speed is very essential.
RF waves are used to transmit information across very long distances, and RFID is no different. The RF waves can reach very long distances especially when powered. This kind of range is very desirable in certain applications like animal tracking where the animal being tracked might move a couple of kilometers. But this type of range is not desirable in applications like cash cards or passports. Malicious people can receive your information and clone it into another tag and use it for themselves. This is where NFC comes in.
Objects that are tagged with NFC are usually passive because it does not require that much range. Some have even employed shielding to further reduce the chance of other people being able to read the information. The shielding became necessary when it was discovered that even non-powered tags can still be read over 10 meters away with specialized equipment. Currently, some mobile phones are being equipped with NFC so that they can be used as a cash card of sorts since almost all people carry mobile phones anyway.
1.NFC is just an extension to RFID technology
2.RFID is capable of accepting and transmitting beyond a few meters while NFC is restricted to within 4 inches
3.RFID has a wide range of uses while NFC is usually used in cases where security is needed
4.Some mobile phones are equipped with NFC

Great Article - 6 Ways to Better Living: Inside an Internet of Things Home

Article Source.

What if we took the leading sensor-based products currently being developed or already on the market, put them all under one roof, and added a typical American family? Would they just be the techiest family on the block, or would it have a significant impact on their lives?
Here are six ways this Internet of Things family can see their lives change. They exercise more, save energy and water, budget better, know where their kids are at any moment, and they'll always have the right lighting for activities in the house.
Bank Account-based Motivation
We talked last month about Green Goose, which is a green egg with an ethernet connection that can sense how many miles a person has ridden on their bicycle instead of a car. This data ultimately could be synced up with each family members' bank account. So if they chose to ride a bike instead of a car, an automatic transfer of the allotted monthly gas money saved goes from a checking account into a savings account. Green Goose has plans for other similar sensors.
Health and Fitness
When it comes to physical fitness, this family has all the devices we explained in our sensors to keep you fit post. From Nike Plus running shoes, which sends running data to Mom's iPod via a sensor, to grandpa's exercise games via Wii Fit to their youngest son's training program via NordicTracks iFit, to Dad's miCoach pacer, this family is being encouraged by sensors to better understand and improve their physical health.
Water Conservation

The Waterpebble is a simple sensor that's placed in the shower. It measures the duration of the first shower, and when the next person takes a shower a green light inside the pebble will turn to orange to let the person know that their shower-time is half way up. Once the shower goes longer than the recorded time, the pebble gives off a red light. The best part is that after each shower the Waterpebble will fractionally reduce the amount of time the person will be allowed to shower. There's also a reset button for when someone in the family is having a bad day and needs a longer shower.
Energy Use Scoreboard
All electrical appliances in this house plug into Picowatt Wi-Fi smart plugs, which allow the family to communicate and control energy usage via a command center like Intel's prototype home energy monitor. This monitor is what the New York Times refers to as an Energy Use Scoreboard, which calculates energy usage and displays costs in real-time. Once this technology hits the market, the family will be able to add a few goal-setting apps to the control panel and they'll have the tools they
need to minimize their energy use.
Alert Services
Last January we reported on Trackle and the emerging era of alert services. In the Internet of Things house not only does Trackle alert the family about vital events and information going on in their neighborhood, but when Mom wants to make sure her daughter gets safely home from school on her own, she simply puts a Touchatag RFID tag in her backpack, which alerts Mom when her daughter is safely home.
Lighting Optimization
Finally, this home's lighting can be regulated by Pachube (pronounced patch-bay) and Arduino. As we reported last summer, light sensors can be connected to Arduino, which is an open-source electronics prototyping platform. The light sensor data is then sent to Pachube, which connects the sensor data to the Web where the lighting can be controlled via twitter or via a home energy monitor.
Overall, it's important to remember that we're still in the early days of Internet of Things. As these products continue to develop we'll find more and more ways for our devices to coax us to refine our health and our environment.
