    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
