Requirements
Functional
- The system should allow for the persistence of sensor readings into a
central repository.
- The system should provide access to a variety of relevant sensor and
chronological data to external clients.
- The system should provide the ability to remove or edit data stored in
the system.
- The system should provide the ability to view custom reports based on
environmental and chronological data.
- The system should have the ability to measure a variety of environmental
factors.
- The system should be configurable by local and remote clients on a
variety of platforms.
- The state of the system should be viewable by local and remote clients on
a variety of platforms.
- The system should respond to environmental changes by applying
configurable rules which adjust the environment.
- The system should allow for integration with other systems such as a home
automation system.
Non-functional
- Small Footprint
- The sensor infrastructure required by the system should be kept to a
minimum.
- The system devices should be optimised for energy efficiency.
- The system should be scalable in such away that adding additional
components does not adversely affect system performance.
- Ease of Maintenance
- It should be straightforward to replace faulty sensors, etc.
- Security
- The system should be secured in such a way as to prevent unauthorised
access and use.
- Accessibility
- The system should be easily accessible.
- The user interface should be intuitive and provide a high level of accessibility.
- Reliable
- System must handle failures such as:
- Dead devices
- Communication problems
- Power supply issues
- Provide useful environmental information
- Provide a solution to the cost optimization problem, with the
following constraints:
- Safety
- Interaction with the system should be intuitive
