DISPATCHING MAP MATCHING TASKS BY CLUSTER SERVER IN INTERNET OF VEHICLES

摘要

The technical solution relates to a method and apparatus for dispatching a map matching task at a cluster server in the Internet of Vehicles. Specifically, there is disclosed a method, comprising: determining a road segment group set that corresponds to a current time period, and a correspondence relationship between each road segment group in the road segment group set and a computing node of the cluster server, wherein the road segment group is a group of road segments which are grouped according to the number of computing nodes of the cluster server and the dissimilarity between divided road segments in a road network; in response to receiving multiple GPS sampled data from a vehicle, generating a map matching request according to the multiple GPS sampled data; and in response to generating a map matching request and obtaining a road segment to which the latest location of the vehicle belongs, sending the map matching request to a computing node that corresponds to a road segment group to which the obtained road segment belongs, for map matching. The method according to the embodiment of the technical solution can solve conflicts occur when computing nodes of the cluster server process map matching tasks.
