Abstract :
In this work reliability issues regarding a new SIP-based architecture for location tracking are investigated. This new architecture works across different positioning technologies (particle filters and GPS) and provides optimal position tracking in real time for an outdoor mobile user. A new adaptive SIP retransmission timer is proposed that is designed specifically for real time location tracking in an outdoor environment. This new retransmission timer is aligned with the motion model of the mobile user. We extend the architecture to allow other location based network information, such as that residing in quality of service (QoS) aware servers, to be seamlessly incorporated. The architecture we propose here, builds on our already deployed GPS-assisted particle filter tracking algorithms and our position-based QoS presence system.
