摘要

本文研究了一种新的基于sip的位置跟踪体系结构的可靠性问题。这种新架构可以跨不同的定位技术(粒子滤波和GPS)工作，并为户外移动用户提供实时的最佳位置跟踪。针对室外环境下的实时位置跟踪问题，提出了一种新的自适应SIP重传定时器。这种新的重传计时器与移动用户的运动模型是一致的。我们扩展了该体系结构，以允许其他基于位置的网络信息，例如驻留在服务质量(QoS)感知服务器中的信息，被无缝地合并。我们在这里提出的架构，建立在我们已经部署的gps辅助粒子滤波跟踪算法和我们基于位置的QoS存在系统之上。

Reliability Issues in a SIP based Location Tracking Architecture

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.
