Kumar, Neeraj; Rodrigues, Joel J. P. C.; Lloret, Jaime; Dua, Amit(Springer Verlag (Germany), 2015-04)
Location determination is one of the most dif-
ficult tasks to be achieved in Vehicular Ad Hoc networks
(VANETs), as the nodes change their positions quickly due
to high velocity. So, data dissemination to the ...
