This study effectively improves the packet delivery rate and Peak Signal-to-Noise Ratio while reducing end-to-end delay through a trust-based node-disjoint multipath routing mechanism.
Multipath routing is an effective approach to transmit large multimedia data in sensor networks to satisfy the QoS requirements. This paper focuses on QoS-aware trust-based node-disjoint multipath routing mechanism between source node and destination node in two-layer clustered multimedia sensor networks. First, node-disjoint and non-interference logical pipes are created. Then, based on the trust value of single sensor node, single routing path and multiple routing paths, the node-disjoint non-interference routing paths are established. And the update and routing update process is also designed. Finally, the proposed routing method are well simulated. The simulation results show that our QoS-aware trust-based routing mechanism can effectively enhance the packet delivery rate, reduce the packet end-to-end delay, and increase the Peak Signal-to-Noise Ratio.
