Node-disjoint multiple routing is an effective mechanism for delivering rich multimedia in wireless multimedia sensor networks. And congestion is one of main problem must be addressed in routing scheme. Considering routing paths established are of non-interference and node-disjoint, each routing path can be viewed as a node. And then a queueing network model is introduced to abstract multiple type multimedia packets delivery process through node-disjoint routing paths in cluster based wireless multimedia sensor networks. At cluster header, QoS-aware traffic schedule scheme is adopted to dispatch packets of different priorities. The scheme consists of receiving buffer queue, traffic packets dispatching service based on generalized Erlang distribution, and priority-based sending buffer queue. Then we model the optimal decision control process of multipath routing in congestion state. Finally, we simulate the proposed queueing network model with trust-based load balancing scheme. And the results reveal that our proposed model is more suitable for node-disjoint multiple paths to deliver rich multimedia information, such as video and images.
