Abstract
A high-reliability and high-robustness routing method for MSR-WSNs is provided, including: S1: generating an initial dynamic topological structure of MSR-WSNs; S2: determining a cluster head node for any maritime search and rescue node, and joining a corresponding cluster to obtain a set of clusters; S3: calculating a predicted forward distance of a maritime search and rescue data packet of a target node; S4: calculating the correct reception rate among nodes under the communication link of the maritime search and rescue environment; S5: calculating and sorting the priority of each relay node from high to low according to the priority; S6: when carrying out the task of forwarding maritime search and rescue data packets, the target nodes select the candidate relay nodes in turn and combined with the reliable response mechanism to forward until the maritime search and rescue data packets are successfully received by search and rescue ship.
