  In this paper, we characterize the stability region of multi-queue
multi-server (MQMS) queueing systems with stationary channel and packet arrival
processes. Toward this, the necessary and sufficient conditions for the
stability of the system are derived under general arrival processes with finite
first and second moments. We show that when the arrival processes are
stationary, the stability region form is a polytope for which we explicitly
find the coefficients of the linear inequalities which characterize the
stability region polytope.
