The Pervasive Internet

As I briefly mentioned about subtle changes in the blog yesterday, RFID and WSNs, two merging technologies will be focus of our attention. Wireless sensor networks or WSNs will bring about the revolution of "The Pervasive Internet" or as Anita Campbell mentioned in her comment today "The Internet of Things". So what does this "Internet of Things" involve?

Providing intelligence to the manufactured objects to be self-aware, to respond to the changes in it's environment is the essence of the Wireless Sensor Networks. How nice it will be if your Computer network can also control your office lighting, airconditioning requirements and your phone systems. This is possible only if these disconnected networks talk to each other. WSNs has the capability to make this happen.

WSNs combined with RFIDs increase the range of RFIDs, thus reducing(not eliminating) the needs for costly RFID readers. This can be done by using a network of sensors to pickup the signal from RFID tags and relay that signal thru the network to the nearest RFID reader.

I can provide an excellent example of connecting your complete house with WSNs, but then I may invite the wrath of privacy groups, instead tomorrow I will present an example of RFID and WSN usage in industrial environment.

Financial Plan - Assumptions - 2

There is a slight change since yesterday. I will not fill the Assumption table in yesterday's post. Instead, I will discuss what each variable means. This way table is more meaningful, rather than mere numbers. Variables_Used_for_Assumption Units_Used Explanation_of_Variables Average Monthly Sales US $000s Here you can enter net sales value. Desired average finished inventory % of Sales Does not apply to Service / Distribution business. For Manufacturing business, this variable is % of sales. Cost of materials/goods As % Sales This value is set to zero for Service business and for Distribution it refers to the purchases/inventory for resale. Target materials/goods inventory US $000s This value is set to zero for Service business and for Distribution it refers to the purchases/inventory for resale. Average monthly direct costs US $000s It is set to zero for for Distribution business Average monthly overhead expenses US $000s Interest and Depreciation is not included Opening total co...

The Circle of Information

First there was light, then there was a Light Bulb controlled by a switch, then came Internet and the light bulb was still controlled by a switch, finally Pervasive internet will come and control the Light Bulb. This is the vision of Pervasive Internet. This next version of Internet is destined to control : * Industrial - Capital Equipment, Automation & Control Equipment * Power - Meters, Distributed Generators, Electricity Grid and Pipelines * Healthcare - Medical Devices * Home / Consumer - Game Systems, Consumer Electronics, Appliances * Buildings / Facilities - Access Controls, Office Equipment, HVAC / Environmental Systems * Retail - Lighting & Refrigeration Systems, Scanners & Registers * Transportation - Vehicles, Airplanes, & Intermodal Transport This congregation of Internet with the smart devices will create a serious shift in the advancement of the digital revolution - forming a comprehensive "digital neural net". Imagine a large office building in ...

Brainstorming - RFID Discussion

Radio Frequency ID tags or RFID Tags came into limelight when Walmart insisted their suppliers to have them by January 1st 2005. RFIDs have existed for few years and are used as security devices on Music CDs, Games CDs and DVDs and various other areas. There are however many unexplored areas where RFID solutions can be used. We are going to explore some of these areas for potential product and/or services that Businessworks Inc can provide. If we go with RFID based solutions, manufacturing RFIDs will not our goal as it can be prohibitively expensive. Our goal would consist of using RFIDs readily available and building custom solutions and sell it to Government and private organizations. This idea ranks very high in our potential list of technologies. Tomorrow I will discuss Nanotechnology.
