Method and appartus for determining the location of a node in a wireless system

摘要

During operation, a node (104) will determine a particular probability of achieving a successful location. When battery resources are below a threshold the node will utilize a minimum probability for success in determining how many time-slots to collect RSSI measurements. However, if battery resources are above the threshold, a higher probability of achieving a successful location than the minimum may be utilized. After the particular probability of achieving a successful location is determined, a number of time-slots (L) are determined. L comprises a number of time slots that the node must remain awake for to achieve the particular probability of achieving a successful location. The node will then remain awake for L time slots, and compute a location based on measurements taken within those L time slots.
