  As large scale deployment of smart devices in the power grid continues,
research efforts need to increasingly focus on efficient communication of
generated information. This paper describes a strategy for static routing and
scheduling of messages in a multi-hop wireless Smart Grid Neighborhood Area
Network (NAN) with multiple source nodes and a common set of destinations or
gateways. The problem is formulated as a Mixed Integer Linear Program (MILP)
and solved using commercial optimization solver CPLEX. Feasibility of the
scheme is demonstrated using different network models, constraints, message
injection rates, and initial conditions. It is shown that the proposed approach
can be used to generate an optimal link schedule for collecting user-generated
bids in a transactive energy market in the least possible time. It is also
shown that the methodology is applicable to multiple destination nodes and that
their location affects message delivery time.
