In this paper, we introduce the reputation mechanism into MSRMultipath Source Routing in Mobile Ad Hoc NetworkMANET. This mechanism maintains a reputation table in each node. Before routing setup, the source node will verify the reputation degree of each node. If a node-s reputation degree is lower than the limited value, it will be isolated. As a result, several safe routing paths are established between source node and destination node. Then the routing security in MANET is improved. The simulation results show that the improved routing protocol has a better packet delivery fraction and lower End-to-end delay in MANET which includes malicious nodes.
