research aims
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 disasters within the society
  • Investigating context models is required for designing efficient and expressive messaging and addressing services.

Objectives of literature survey

  • Investigate the concept of context aware messaging and addressing.
  • Presents an overview some common applications that use context-aware messaging.
    • The context aware messaging applications that are used for emergency purposes.
      • smart bushfire monitoring and detection system using GSM technology
      • A bushfire monitoring and detection system for smart homes using ZigBee technology
    • The context-aware messaging applications that used for guides and reminders.
      • ComMotion, Cybre-Minder, Elvin…etc
    • The context aware messaging applications for social purposes which includes: communication and interaction between people.
      • Context-Mediated Social Awareness, Live Contacts, Micro-Blog, InfoRadar…etc
background
Background
  • Context awareness is more than twenty years old (Coppola, et. al., 2005).
  • Context-awareness is a key aspect of new applications in the field of ubiquitous computing.
  • Mobile and ubiquitous computing environments can now match and even replace traditional desktop computing.
  • Chen and Kotz 2000, discuss the relation between context-aware computing and mobile computing model in which applications can determine and take advantage of contextual information.
  • Contextual information can be used as an alternative to old fashion addressing techniques such IP addresses for communication purposes (Geiger, et. al., 2009).
what is context
What is Context?
  • Schilit et. al., (1994) divides context into three categories:
  • Computing context.
  • User context.
  • 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 “knowledge about the user’s and IT device’s state, including surroundings, situation, and to a less extent, location”.
context aim
Context Aim
  • 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 user’s situation and surrounding in order for the application to progress and execute a task (Dey’s, 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 to application.

  • In recently year we notice that the use of the number of different types of context in applications increased significantly as compare to the previous years.
slide16

Proposal for Assist-Me System

  • Emergency systems refer to the measures that we put in place in order to help us effectively deal with disasters within the society
  • Modern technology such as remote sensing with the use of wireless devices increases the chances of detecting slight changes in the environment.
  • The use modern technology in disaster management simplifies decision making saving time and providing help where necessary .
slide17

Spatial relations (Enclosing Space)

  • Spatial data models where the use of geographic information system (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
