Vehicular Ad hoc Network (VANET) was designed to provide wireless communication capabilities among vehicles. In VANET, two main categories of applications can be considered: Safety application and comfort application. These applications and special characteristics of vehicular network impose different challenges which require different Medium Access Control (MAC) and routing. One of the characters of VANET is simultaneous variation in vehicles’ density. This density variation causes VANET to be considered as a subgroup of partitioned ad hoc networks. Because comfort applications are usually delay tolerant, Store-Carry-Forward (SCF) is proposed as a solution in VANET. In this thesis, SCF is analyzed; the effects of SCF on the number of hops in multi hop vehicular communication are investigated. It is shown that SCF reduce number of required hops dramatically. In the second part of the thesis, based on local density estimation of vehicles, a forwarding procedure is introduced. This estimation uses velocity and acceleration information. Comparing to previously proposed Artimy estimation, our proposed method is more accurate.
