Pervasive Technology and Mobile Computing

The realisation that pervasive technology can provide a direct link between data and people has crystallised into the idea of participatory sensing, which appropriates everyday mobile devices such as cellular phones to form interactive sensor networks that enable public and professional users to gather, analyse and share local knowledge.

Its potential for data collection at a high granularity in space and time, very difficult for scientists to achieve otherwise, together with its potential for citizen involvement at all layers of society, make this an extremely promising tool for monitoring and managing the environment.

Sound Pollution in Bangladesh

I think there have no proper law against this terrible sound pollution in Bangladesh. My hearing system should be damage for this heavy sound of ambulance and Police team’s vehicle.

Though sound pollution happening in many countries, But In Bangladesh, sound pollution is another one greatest issue for the environment.
Most probably, Ambulance, VIP & Police Protocol team vehicle always create so enormous sound on the road that they can go forward swiftly.
Absolutely, this is their duty. But, when an ambulance and Police vehicle fall into a traffic jam. They must try to do wait and stop their whistle of vehicle; otherwise they misconduct the sound pollution law.

Zigbee | IEEE 802.1.5 | IEEE Standard 802.15.2012

A second personal area network standardized by the IEEE is the 802.14.5 standard [IEEE 802.15 2012] known as Zigbee. While Bluetooth networks provide a “cable replacement” data rate of over a Megabit per second, Zigbee is targeted at lower powered, lower-data-rate, lower-duty-cycle applications than Bluetooth. bluetooth_street_small



For example, home temperature and light sensors, security devices, and wall mounted switches are all very simple, low-power, low-duty-cycle, low-cost devices.
Zigbee is thus well-suited for these devices. Zigbee defines channel rates of 20, 40, 100, and 250 Kbps, depending on the channel frequency.

Artificial Intelligence Concepts

One of the first games to be beaten by computer, tic-tac-toe can be used to teach artificial intelligence concepts.



Is the Job Right for You – 4 Things Need to Know


We need Clean and Traffic Jam free Dhaka City

The Southern section of the city Dhaka important place will be covered through WiFi as well as make Wireless Internet WiFi zone.
That’s a good idea. But, remind this a country never should be Digital only setup WiFi.

A country should be digital, when will make clean city, proper transport system, good highway, lane, suitable transport road and good drainage system.


In computing, a server is a computer program or a device that provides functionality for other programs or devices, called “clients”. This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. in computing System, there have different types of E-mail server : POP3, IMAP, SMTP, NNTP, LDAP, etc.

  • Post Office Protocol 3 (POP3) servers hold incoming e‑mail messages until you check your e‑mail, at which point they’re transferred to your computer. POP3 is the most common account type for personal e‑mail. Messages are typically deleted from the server when you check your e‑mail.

  • Internet Message Access Protocol (IMAP) servers let you work with e‑mail messages without downloading them to your computer first. You can preview, delete, and organize messages directly on the e‑mail server, and copies are stored on the server until you choose to delete them. IMAP is commonly used for business e‑mail accounts.

  • Simple Mail Transfer Protocol (SMTP) servers handle the sending of your e‑mail messages to the Internet. The SMTP server handles outgoing e‑mail, and is used in conjunction with a POP3 or IMAP incoming e‑mail server.

    Windows Mail also supports additional server types: Network News Transfer Protocol (NNTP), which is used to read and post newsgroup messages, and Lightweight Directory Access Protocol (LDAP), which is used to access directory services.
