  This paper investigate joint scheduling and power control for V2V multicast
allowing multihop communication. The effects of both co-channel interference
and adjacent channel interference are considered. First, we solve the problem
with the objective of maximizing the throughput and connectivity of vehicles in
the network. Then extend the same problem formulation to include the objective
of minimizing the latency and the average age of information (AoI), which is
the age of the latest received message. In order to account for fairness, we
also show the problem formulation to maximize the worst-case throughput and
connectivity. All the problems are formulated as mixed Boolean linear
programming problems, which allows computation of optimal solutions.
Furthermore, we consider the error probability of a link failure in all the
problem formulations and accommodate the probability requirements for
satisfying a certain throughput/connectivity/latency/AoI. In order to support a
large V2V network, a clustering algorithm is proposed whose computational
complexity scale well with the network size. To handle the case of zero channel
information at the scheduler, a multihop distributed scheduling scheme is
proposed.
