Claim:
1. A method for dispatching a map matching task at a cluster server in the Internet of Vehicles, comprising: determining, by one or more processors, a road segment group set that corresponds to a time period; determining, by the one or more processors, 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, wherein the dissimilarity between divided road segments is based, at least in part, on whether any two road segments intersect; monitoring, by the one or more processors, multiple GPS (global positioning system) sampled data from a vehicle that indicates a road segment; generating, by the one or more processors, 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, by the one or more processors, in response to generating the map matching request and not obtaining a road segment from the multiple GPS sampled data the map matching request to a random computing node.
