With the recent advancement in the mobile technology, devices are equipped with location computing facility. Devices are mounted with real entities such as human, animals, vehicles etc. In Location Based Services, user carrying device seeks service and hence user's location information is compromised and can be misused by service providers. In this paper, we present the review and propose the enhanced mechanisms to protect the location privacy of mobile users. It necessary to observe that to get quality of service, user needs to send precise location, while to protect privacy, we need to have balanced view regarding revealing location to service provider. Quality of service, Performance, Energy consumption, Network bandwidth consumption and Privacy strength are the parameters of importance which should be the objectives of research while providing the location based services. © 2013 IEEE.
