Algorithm 1
Obtain global location information of a moving object.
input interested moving object set P | output moving object set P with updated location information | Steps: | to mapper: | P.get(); // read object assigned to current mapper from input cache | foreach p in P | p.pos=p.posg+p.e.wg; // compute global location information | P.send(); // send the result to output cache | to reducer: | P.get(); // gather objects from each mapper |
