An efficient minimum-process non-intrusive snapshot algorithm for vehicular ad hoc networks

The advent of Vehicular Ad Hoc Networks (VANETs) has made communication and information exchange between vehicles possible. This has allowed us to create mobile distributed applications running on VANET and has also brought forward several new challenges in distributed algorithm design. Among these algorithms, here we are interested in the snapshot algorithms, which are used to recover an application from failure. Snapshot algorithms for Mobile Ad hoc Networks (MANETs) have been studied for quite some time and VANET would form the biggest MANET ever implemented. Therefore, designing a reliable snapshot algorithm for VANET is still an open research issue. In this paper, we propose an efficient minimum-process non-intrusive snapshot algorithm for mobile distributed application running on VANET and this is the first work of this kind on this issue.
