… First, we represent the map M by set FS, the set of all the grids in the movable space (free
space) of M. That is, FS is the set of all the grids which are not included by the obstacles. …

… Location-based protocols: Location-based routing protocols use a vehicle’s self-configuring
positioning mechanism and GPS to determine its location from road maps. Then, suitable …

… The vehicles have a transmission range of 400 m and move based on a real road map,
according to the Krauï¿ 1/2 mobility model [11]. To simulate highly loaded network scenarios, the …
