Abstract |
: |
Pedestrian LBS system is basically compound of a mobile device with a GPS receiver, connected to a service provider via means of wireless communication. The performance of LBS system is directly affected by each component forming its architecture. Firstly, the end-user mobile device is still experiencing a lack of enough storage, limitations in CPU capabilities and short battery lifetime. Secondly, the mobile wireless network is still having problems with the size of bandwidth, packet loss, congestions and delay. Additionally, in spite of the fact that GPS is the most accurate navigation system, there are still some issues in micro scale navigation, mainly availability and accuracy. Finally, LBS server which hosts geographical and users information is experiencing difficulties in managing the huge size of data which causes a long query processing time. The aim of this paper is to test, analyze and discuss the performance of each component of LBS for pedestrian navigation systems in micro-scale environments. In addition, this paper proposes solutions and recommendations for most of those shortcomings. |
