Stochastic Evaluation of Geographical Forwarding in Vehicular Ad Hoc Networks
نویسندگان
چکیده
Vehicular ad hoc networks which support active safety applications have to address data packet recipients by taking the position of the vehicles into account. This leads to a two step forwarding procedure. Firstly, in line forwarding mode data packets are sent to a target area and in a second step the data packets are distributed inside the target area (area forwarding mode). This contribution introduces methods of stochastic analysis to estimate the performance of these two forwarding phases.
