Open WSN indoor localization platform design

The fast development of WSN (Wireless Sensor Network) provide the solution to indoor localization application. To which, the position accuracy become the essential problem need to solve. At the same time the cost of software development also impede the indoor application. This paper introduces in detail the composition of the whole system and the design of localization algorithm based on RSSI. Through computing the relevance of adjacent nodes of target tag, the enhanced localization method is introduced and designing a LBS platform based on FOSS middle ware in a new way prove the possibility to build a high accuracy indoor localization system based on WSN at low cost.
