Research on WI-FI Fingerprint Indoor Localization based on Group

WI-FI fingerprint is one of most common used indoor localization algorithms.However,there always existsignificant errors.To improve the accuracy of WI-FI fingerprint,WI-FI fingerprint localization algorithm based on group are designed and implemented in smart. In this paper,firstly the definition of a group is introduced,and then a Minimum Edit Distancebased algorithm to recognize groups is proposed. Exploiting the physical distance among people in the group,a localization algorithm is designed.Experiments showed thatthe accuracy of WI-FI fingerprint localization can be improved.
