Research Aims We aim to investigate context-aware messaging and addressing
for emergency situations . Assist-Me is an emergency alert that will be activate to help
avoiding disaster.
Outdoor emergency systems refer to the measures that we put
in place in order to help us effectively deal with disasterswithin the society
Investigating context models is required for designing efficient
and expressive messaging and addressing services.

Schilit et. al., (1994) divides context into three categories:
i. Computing context.
ii. User context.
iii. Physical context.
Chen and Kotz (2000) continued that work and introduced
fourth category of context called time.
Dey et. al.,1999 define context as any information that can be
used to distinguish the situation of an entity, where entity can
be a person, place, or object that is considered relevant to the
interaction between the user and application.
Schmidt et al.,(2002) defines context as knowledgeabout the
usersand IT devicesstate, including surroundings, situation,
and to a less extent, location.
What is Context?

The basic aim of context awareness is to provide computers with
situational information in order to execute tasks.
Context awareness aim can be found as the use of any
information related to the users situation and surrounding in
order for the application to progress and execute a task (Deys,
2001).
Haseloff (2005) defines the aim of context awareness as
providing computers with situational or contextual information
as a result of which they accordingly adapt the execution of tasks
and the way of interacting with users.

In summary, the number of types of context being used in the
application varies with time to time and with application toapplication.
In recently year we notice that the use of the number of
different types of context in applications increasedsignificantly as compare to the previous years.

Emergency systems refer to the measures that we put in placein order to help us effectively deal with disasters within thesociety
Modern technology such as remote sensing with the use of
wireless devices increases the chances of detecting slightchanges in the environment.
The use modern technology in disaster management simplifiesdecision making saving time and providing help wherenecessary .

Spatial relations (Enclosing Space)
Spatial data models where the use of geographic informationsystem (GIS) in providing information concerning current
events is increasingly attracting global interest in a number of
fields.
spatial can be anything that are related to a certain area or
space not necessary physically geographic such as the human
activities as going to the farm.
Spatial awareness allows the system to autonomously resolve
and use its spatial properties to relate these properties to the
spatial properties of other systems
