For the past few years, this has actuated investigators to find and inquire scalable expelling communications protocol that are full-bodied adequate for execution in VANETs. To insure the cogency of vehicular network, a suitable information interchange between node extremities of a network expects, amid additional features, the comprehension of node mobility below dissimilar environmental circumstances. The try out comprises of two vehicles mobile nodes that are associated with an ad-hoc Wi-Fi association and a stationary place post with a committed WiMAX association to one of the vehicles. Wi-Fi ad-hoc manner admits the devices to pass on with one another without the exercise of access point APand all devices in orbit associate in a P2P manner.
Show full item record Abstract A major component of future communication systems is vehicle-to-vehicle V2V communications, in which vehicles along roadways transfer information directly among themselves and with roadside infrastructure.
Despite its numerous potential advantages, V2V communication suffers from one inherent shortcoming: One possible way to improve this coverage is to allow the vehicular nodes to connect to the more reliable cellular network, especially in cases of loss of connectivity in the vehicular network.
In this thesis, we analyze this possibility of boosting performance of VANETs, especially their node coverage, by taking assistance from the cellular network.

While there has been a signifcant work on modeling wireless networks using random spatial models, most of it uses homogeneous planar Poisson Point Process PPP to maintain tractability, which is clearly not applicable to VANETs. Therefore, to accurately capture the spatial distribution of vehicles in a VANET, we model the roads using the so called Poisson Line Process and then place vehicles randomly on each road according to a one-dimensional homogeneous PPP.
As is usually the case, the locations of the cellular base stations are modeled by a planar two-dimensional PPP.
Therefore, in this thesis, we propose a new two-tier model for cellular-assisted VANETs, where the cellular base stations form a planar PPP and the vehicular nodes form a one-dimensional PPP on roads modeled as undirected lines according to a Poisson Line Process.
The key contribution of this thesis is the stochastic geometric analysis of a maximum power-based cellular-assisted VANET scheme, in which a vehicle receives information from either the nearest vehicle or the nearest cellular base station, based on the received power.
We have characterized the network interference and obtained expressions for coverage probability in this cellular-assisted VANET, and successfully demonstrated that using this switching technique can provide a significant improvement in coverage and thus provide better vehicular network performance in the future.
In addition, this thesis also analyzes two threshold-distance based schemes which trade off network coverage for a reduction in additional cellular network load; notably, these schemes also outperform traditional vehicular networks that do not use any cellular assistance. Thus, this thesis mathematically validates the possibility of improving VANET performance using cellular networks.Tra c Congestion Estimation in Vehicular Ad Hoc Networks A thesis submitted in partial ful llment of the requirements for the degree of Bachelor of Technology (Honours).

Vehicular ad-hoc Network technologies are emerging. Vehicular ad hoc networks (VANETs) are de ned a as subset of mobile ad hoc networks (MANETs) with the distinguishing property that the nodes present in here are vehicles.
