Scalability Optimization of Seamless Positioning Service

Abstract EN

Recently positioning services are getting more attention not only within research community but also from service providers.

From the service providers point of view positioning service that will be able to work seamlessly in all environments, for example, indoor, dense urban, and rural, has a huge potential to open new markets.

However, such system does not only need to provide accurate position estimates but have to be scalable and resistant to fake positioning requests.

In the previous works we have proposed a modular system, which is able to provide seamless positioning in various environments.

The system automatically selects optimal positioning module based on available radio signals.

The system currently consists of three positioning modules—GPS, GSM based positioning, and Wi-Fi based positioning.

In this paper we will propose algorithm which will reduce time needed for position estimation and thus allow higher scalability of the modular system and thus allow providing positioning services to higher amount of users.

Such improvement is extremely important, for real world application where large number of users will require position estimates, since positioning error is affected by response time of the positioning server.
