A Node-Disjoint Trust-Based Multipath Routing Mechanism For Multimedia Sensor Networks

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.
