What is Frugal Engineering !

Frugal Engineering is the science of breaking up

complex engineering processes into its basic

components and then re-building each component inthe most economical manner. The end result is a

simpler, more robust and easier to handle final

process. It also results in a much cheaper final

product which does the same job qualitatively and

quantitatively as a more expensive complexly

engineered product.

Post Disaster Scenario :

Loss of Life and livelihood

Lives at stake , of those who survived

Information and communication system jammed orcrashed due to hardware losses

Interrupted Power Supply


5/20

Need for an Information System during

post disaster scenario :

Relief teams decide where to search for survivors

Assessing what basic supplies are needed to support

the survivors

Where to deliver them.

It becomes very difficult for displaced families to be

notified about their relative.


6/20

Implementation of a frugal Information

System and its Requirements:

A system with basic capabilities and sufficient

bandwidth.

That meet the most pressing needs .

A basic communication tool most people possess.

8/20

A MOBILE PHONE , with a GSM SIM , working on

Frequency as well as Time Division Multiplexing , that

we can say as a basic communication tool most peoplepossess .

(only resource a survivor

may have for

communication)


9/20

Since, at a time of a calamity or a disaster most

of the hardware devices running a cell phone

crash down.

There comes a demand for external tool, which I

call Emergency Server Station (ESS).


10/20

ESS is a hot air balloon controlled automatically or Manually.

Left over a disaster struck area immediately after few hours,

from a nearest take off point.


11/20

ESS is embedded with systems

like :

Broadcast Antenna

Point to Point Antennas

Radar System

Database Storage and Management System

Micro programmed System

Working of

Emergency Server Station


14/20

Antennas :

ESS consisting with both type of antennas point to

point as well as broadcast antennas.

Broadcast a certain bandwidth of Frequency termedas Emergency Class Bandwidth (ECB)

Sending and receiving information to the otherunaffected states

Providing situation details to the relief teams

Linking the affected area with a satellite


15/20

Emergency Class Bandwidth (ECB)

Emergency Class Bandwidth (ECB) , will be inherited in each

GSM SIM at the time of manufacturing.

Will have a standard ringing number , called ECB number

(A small form of 911 concept).

The user with default operator can switch over to workingECB manually, only when an Emergency Server Station

broadcasts a standard ECB.

Thus, the new technology wont harm the profit as well asinterest of mobile operators


16/20

Radar :

Due to Emergency class Bandwidth from ESS, any mobile phone

in a Disaster affected area can call on a broadcasting frequency.

The system is so designed that after first three seconds a beep

will sound .

After first 30 seconds the ring would automatically cut out

providing the radar with a callers latitude and longitude.

Latitude and longitude will be further transferred via antennas

for sending information to the relief teams


17/20

Database Storage System :

The calling mobile no. will be identified and stored on a Database

system installed on Emergency Server Station .

Exactly after first three seconds a beep will sound to confirm the user

that the calling no. has been added to database including time of call.

The Database information will be continuously transmitted to satellite

station, non effected area and relief teams

providing there stats to their families

Displaced Families also avail an advantage through installed Database

system.

As soon as one calls to a misplaced family member, and if that no. to

which one calls is already stored in Database (by similar process of

calling on ECB no. and storage of personal no. storage after 3 seconds) ,

the ring on ECB no. will beep as a notifier straight after 10 seconds

CONSTARINTS :

Since the entire research is concerned over Frugal Information System ,theESSis limited to a certain bandwidth that dont allow , point to point phonecalls and direct communication medium , to minimize power consumption.

The battery life of mobile phone is the whole sole responsibility of theuser, but since the Emergency Case Bandwidth is integrated with a GSMSIM , a mere SIM can come in handy to provide individual location andDatabase entry, even with different mobile phone

Installing Emergency Class Bandwidth with default bandwidth of theservice provider on each GSM SIM , must be made mandatory byGovernment for making the Emergency Server Station globalised for everySIM and server provider.


20/20

CONCLUSION

In summary, I propose

Use what people already have, cell phones, as the foundation.Unfamiliar devices especially prepared for disasters were notused.

Governments should invest in the resources to create quicklythe infrastructure to sustain a frugal IS.

The public and private sectors must collaborate to ensure theeffective integration of the government disaster infrastructureand privately owned mobile devices.
