A Comprehensive Survey on Indoor Positioning System and Its Evaluation

Locating people in the indoor locations have gained great interest in this decade, and so positioning systems have be widely evaluated for accuracy. Major reason for positioning people are guide them to a certain place, locating them and assisting organizations and companies with their assets management. Many techniques and mechanisms were presented to resolve the people positioning problem and to enhance the accuracy of the existing systems. In the current scenario, one of the many existing wireless protocols or standards such as RFID, Bluetooth or Wi-Fi or Infrared is chosen the working protocol for indoor positioning. In recent days, many indoor positioning systems (IPSs) have been developed to make location information of people or devices available for processing. With location information available for users, users can make efficient use of applications which depend on locations for providing efficient services. Personal Area networks (PANs) are designed to meet the users? location based needs and interconnect users? handheld devices embedded with various standards or communication methods in various places to form one entity of network. Location-aware services are required to be developed in PANs to offer adaptive and flexible personal services and thereby improve the quality of lives. This paper gives a evaluative survey of various IPSs, including both, the research-oriented solutions as well as commercial products. Comprehensive performance comparisons including accuracy, security etc. are addressed.
