Available bandwidth estimation in GPSR for VANETs

Proceedings of the third ACM international symposium on Design and analysis of intelligent vehicular networks and applications, 2013
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 [12]. Instead, we propose a new ABE+ that includes a new function to estimate the probability of losses.
