Research On Hybrid Positioning Performance For Mobile Terminals In LBS

The purpose of the smart city is to make the lives of the people more convenient and intelligent.Location based services are an essential service.In daily life,many applications such as take-aways,dredging cars,car navigation,store shopping,and parking lot search are inseparable from the positioning.However,we only have mobile terminals that are portable and can obtain location information.Therefore,location-based services are Research on the performance of portable mobile terminals has become a trend.More and more researchers are now researching the automatic matching algorithm of positioning technology in indoor and outdoor positioning.When the device is placed in indoor and outdoor environments,how to automatically select the positioning technology to enable the user to have the best experience is the key to the problem.In response to this situation,we propose the concept of user satisfaction to solve this problem.User satisfaction is the degree of user satisfaction with various location services in different application scenarios.In different application scenarios,priority ranking is given to difsferent positioning technologies in order of the value of user satisfaction,improving user experience and providing experimental basis.Firstly,this paper actually measures the data of time,precision,and battery power consumption,and then establishes a model of user satisfaction with single factors of weather forecast,vehicle navigation,and drip-and-drop vehicles.Then,an integrated satisfaction model is established,and finally,according to the model.Calculate the user satisfaction of each positioning technology in different scenarios.It can then be concluded that the optimal positioning technique is selected in a certain scenario.
