Response time

Definition

Response time refers to the duration it takes for a system to react after an input is received. In the context of range-based localization techniques, response time is critical as it affects the speed and accuracy of determining the location of sensor nodes based on distance measurements from reference points. A shorter response time enhances the overall efficiency of the localization process, leading to better real-time performance in various applications.
