AbstractVehicular Ad hoc Network VANET was designed to provide wireless communication capabilitiesamong vehicles In VANET two main categories of applications can be considered Safetyapplication and comfort application These applications and special characteristics of vehicularnetwork impose different challenges which require different Medium Access Control MAC androuting One of the characters of VANET is simultaneous variation in vehicles density Thisdensity 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 asa solution in VANET In this thesis SCF is analyzed the effects of SCF on the number of hops inmulti hop vehicular communication are investigated It is shown that SCF reduce number ofrequired hops dramatically In the second part of the thesis based on local density estimation ofvehicles a forwarding procedure is introduced This estimation uses velocity and accelerationinformation Comparing to previously proposed Artimy estimation our proposed method is moreaccurate
