Abstract
A processor-based client device may be localized in an indoor area based on Received Signal Strength Indication (RSSI) values from different access points is provided. A general geographic area in which the processor-based client device is located. A position of the processor-based client device on the identified area is determined. A context-aware information is displayed on the processor-based client device once the identified area is determined.
Claims6
An indoor room localization system comprising:
- a memory including training data and response data;
- a processor coupled to the memory, the processor for carrying or having computer-executable instructions to collect WiFi RSSI data corresponding to various sites, the instructions causing a machine to:
- classify the collected WiFi RSSI data into an array of RSSI patterns;
- transmit the classified RSSI patterns to the memory for storing into training data;
- transmit response data identifying classifications of the collected WiFi RSSI data to the memory for storage;
- generate observation vectors from the response data identifying classifications of the collected WiFi RSSI data;
- and
- update categorical distribution parameters using the generated observation vectors to specify a probability that the machine is within a predetermined region;
- and
- wherein a dirichlet distribution is used to classify the collected WiFi RSSI data into an array of RSSI patterns and a mode of the dirichlet distribution is used to specify the probability that the machine is within the predetermined region.
