Recently, the widespread of mobile computing devices (e.g. PDA, cellular phone) and technologies (e.g. GPS, wireless communications) leads to dramatic increase in the use of location based services.
A server can provide location based services using the location information reported by moving objects. In this environment, the cost of update operations can be high since a huge number of moving objects report their location frequently. Thus, an efficient spatial index structure is necessary to manage the moving objects.
This paper suggests a new main memory index structure based on grid file. Also this paper suggests a virtual merge policy that delays merge operations to reduce the cost of update operations. |
