In: ns2|ZigBee

25 Oct 2009

After lots of googling I got this useful blog with lots of must-to-have links for NS2, ZigBee and most of the tools to do the simulation.

We are going to have a course project for network simulation on WPAN and ZigBee and these rare resources are very handy to start with.

NS2 for IEEE 802.15.4/ZigBee LR-WPANs :

  1. Simulation of IEEE 802.15./ZigBee With NS-2
  2. IEEE 802.15.4 Mac Implementation in NS-2
  3. Low Rate Wireless Personal Area Networks (LR-WPANs) NS-2 Platform
  4. Simulative Investigation of ZigBee/802.15.4Zigbee/IEEE 802.15.4
  5. Module for NS2 simulator : http://www.cs.uwm.edu/~mukul/wpan.html

E-payment or e-wallet which is actually implemented as m-wallet is the biggest shot of NFC. Use of m-wallet in e-ticketing is replacing the current payment method such as mobile (SMS, web based) payment or using traditional plastic card. New generations of contactless Mastercard (paypass) or Visa (paywave) cards are available in market for customers. Currently operators are offering mobile payment with NFC-enabled mobile phones. According to reports by 2010 NFC phones are able to replace all kind of payment card or mobile based payment systems.

Balanced Amplifiers – Microwave Encyclopedia – Microwaves101.com

In: My notes

A balanced amplifier has two amplifying devices that are run in quadrature. That is, they are operating 90 degrees apart in transmission phase. A quadrature coupler or splitter on the input phase-shifts the two signals 90 degrees at the amplifier inputs, then a second quadrature coupler on the output “un-phase-shifts” the signals at the amplifier outputs so they combine in phase.

After installed this plugin and tried to activate instead of dashboard I got an error message ” …The used table type doesn’t support FULLTEXT indexes…” DO NOT PANIC read below :

If you receive an error like “The YARPP database has an error which could not be fixed.” or “…The used table type doesn’t support FULLTEXT indexes…” after installing YARPP, either your database username does not have access or you need to change your database engine for “wp_posts” from InnoDB to MyISAM.

to solve the aceess problem visit here and try to run SQL manual.

To change the engine goto to myPhpAdmin and select “wp_posts” table>operations->engine.
