Table 3 Performance evaluation of DCD

From: Energy efficiency in big data complex systems: a comprehensive survey of modern energy saving techniques

Parameter(s)

Evaluation

Performance

Over all Satisfactory in a small enterprise. Can be improved when next transition is already known or have a system model which determine transition interval in order to avoid from overhead of activation and deactivation

Goal

To achieve maximum energy efficiency and minimize energy consumption.

Cost (in terms of man power)

In terms of man power these techniques are hard to develop which require more efforts, advanced techniques and latest technology implication makes it more costly

Switching cost

Whenever switching is done which not only degrade performance but also increase energy consumption

Maintaince

Maintaince of DCD is difficult, mainly if we talk about delays, inactivation, deactivation and intervals predictions this make it very expansive and hard to ménage

Complexity

The complexity of technique increase with non-linear interactions and diverse nature of the complex systems. If the interactions between objects and agents are high, complexity will increase

Response time

These approaches don’t have best response time if a component is deactivated and urgent activation is required then it might take very long time which is performance degradation

Cost (in terms of money)

These are hard to build and are very expensive as well. Logic is burnt on chips or any other component then it becomes more costly
