DISPATCHING MAP MATCHING TASKS BY A CLUSTER SERVER

摘要

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.

1. A method for dispatching a map matching task at a cluster server in the Internet of Vehicles, comprising:
determining a road segment group set that corresponds to a time period; determining a correspondence relationship between each road segment group in the road segment group set and a computing node of the cluster server, wherein road segments in the road segment group are grouped according to a number of computing nodes in the cluster server and dissimilarity between divided road segments on a road network; monitoring multiple GPS (global positioning system) sampled data from a vehicle that indicates a road segment; generating, in response to having received multiple GPS sampled data from the vehicle, a map matching request according to the multiple GPS sampled data; and sending, in response to generating the map matching request and obtaining a road segment from the multiple GPS sampled data, the map matching request to a computing node that corresponds to the road segment group to which an obtained road segment belongs.
