Improving the LBS QoS through Implementation of QoS Negotiation Algorithm

Location-based Services (LBS) utilise location awareness for delivery of useful information/content to the user. When considering the Quality of Service (QoS) for LBS, few parameters defined in standards can offer the basic insight into the actual quality of provided service. Usually, the pattern is to strive to the best values for each defined parameter. It is however unnecessary, both from technological and economical point of view, to demand an excellent QoS performance for every LBS. It is much more efficient to use the service and user preferences and construct the appropriate level of QoS for LBS in question. This paper introduces the negotiation algorithm for improving the LBS QoS. Proposed algorithm makes it possible to determine the most suitable level of QoS for particular LBS. Practical validation of the algorithm is also presented, based on the developed prototype.
