This seminar gives an insight into about Natural disasters, their impact on the society and Information Network Infrastructure required disasters. Information basically helps in control & coordination among the rescue field workers during disaster management, Apart from this the following are a few causes which demands the flow of information in the communities during the disaster & post disaster phases are
- Issue of warnings following the identification of an impending hazard and the population at risk
- For administering emergency relief
- Initial evaluation of the impact of a disaster
- Hazard forecasting
- Arrangements for the issue of warnings and evacuations
- For Communications among emergency workers
- Information access and exchange
- To mobilize funds for implementation of disaster-relief activities
- Public access to information on hazards
- 2015-08-22Localization of the population affected and their needs
- Localization of damaged/destroyed infrastructure or services
- Determination of the most affected sectors and areas
- Identification of post emergency projects that require financial
- technical assistance
There are quite a few communication systems currently in use in this sector, but they lack to prove potential in a lot of user demanding aspects as follows:
Support For Heterogenic Devices & Applications
The Personnel on the disaster site have different communication needs and thus they use various kinds of communication devices; the fire personnel may need to communicate with other fire sensors, where as the personnel concerned with relief aid distribution need to video conference with his higher authorities. The search & rescue committees communicate through walkie talkies. The communication equipment may include palmtop, laptop, fax, telephone, mobile phones etc., at the same time the Applications vary in a great extent such as voice, internet access, paging, file transfer, video conferencing etc., thus the network on the disaster site must be able to support all these efficiently.
Availability Of System
A disaster not only affects human but also the technology; in many cases the infrastructural arrangements present in the disaster spot such as telephone lines get severely disrupted due to the disaster & are not useful for communication. Emergency communications need a tangible network that is available round the clock and is not affected by disaster.
Fast Data Access
As the demand for communication is high and only a few communication systems tends to be working; naturally overwhelming loads persists on the network. Thus the network must be capable of providing faster data access & must service high date rates to all its users.
The network must be available for data transmission round the clock; the timely availability of network must be high & the connecting delays must be low. The initial time required for setup of the network must be less in order to enable communication on the disaster site.
There may be conditions that the disaster persists & extends to other areas beyond the disaster site; thus the network must be flexible to relocate itself & it must be easily extendable to other sites. It is odd to expect emergency personnel at the disaster site to communicate from a static standalone communication device. Every second of time is valuable in such situations & it costs many lives; Therefore the need to support communications on the move. To facilitate this, standard architectures such as star/ring/bus is not enough.
The communication network established must be economically feasible for the relief providing organizations. Unless it is affordable the purpose of network can’t be fulfilled.
