Introduction •
Location-based services - major application of mobile geospatial technologies.
•
Two types of the most commonly used queries in LBS Spatial range queries k-nearest-neighbor (kNN) queries •
In these queries, the user has to provide current location to the LBS server which raises privacy concerns.
•
Location cloaking - approach to protect user location privacy
the user’s current location is cloaked into a cloaking region. location-based spatial query is transformed into a regionbased spatial query before being sent to the LBS server
Existing System •
•
Existing techniques cannot be used effectively in a wireless broadcast environment, where only sequential data access is supported. It may not scale to very large user population.
•
In an existing system to communicate with the server, a client must most likely use a fee-based cellular-type network to achieve a reasonable operating range.
•
Third, users must reveal their current location and send it to the server, which may be undesirable for privacy reasons
Proposed System •
This System is a novel approach for reducing the Location query access latency by leveraging results from nearby peers in wireless broadcast environments.
•
Our scheme allows a mobile client to locally verify whether candidate objects received from peers are indeed part of its own Location query result set.
•
The method exhibits great scalability: the higher the mobile peer density, the more the queries answered by peers.
•
The query access latency can be decreased with the increase in clients.
