ABSTRACT
This paper proposes an adaptation of the collision probability used in the measure of the available bandwidth designed for Mobile Ad hoc Networks (MANETs) and which is described in ABE~\cite{abe}. Instead, we propose a new ABE+ that includes a new function to estimate the probability of losses. This new function has been specially designed for Vehicular Ad hoc Networks, to be suited to the high mobility and variable density in vehicular environments. In this analysis we do not only consider the packet size, but also other metrics, such as, density and speed of the nodes. We include the ABE+ algorithm in the forwarding decisions of the GBSR-B protocol~\cite{TrippLatin12}, which is an improvement of the well-known GPSR protocol. Finally through simulations, we compare the performance of our new ABE+ compared to the original ABE. These results show that ABE+ coupled with GBSR-B achieves a good trade-off in terms of packet losses and packet end-to-end delay.

An Enhanced AODV Routing Protocol for Vehicular Adhoc Networks
BDAW '16: Proceedings of the International Conference on Big Data and Advanced Wireless TechnologiesThe key difference of Vehicular Ad- hoc Network (VANET) and Mobile Ad-hoc Network (MANET) is the exceptional mobility pattern and quick variability variable of network topology. The existing MANET routing protocols are inadequate for the VANET. One good ...
