一种面向MANET的启发式恶意节点发现与隔离策略
A Heuristic Strategy of Malicious Node Discovery and Isolation for MANET
摘要
Abstract
In order to adapt the change of network topology and enhance the security of routing protocol,a heuristic strategy of malicious node discovery and isolation is proposed for security applications of Mobile Ad-hoc Network (MANET).It calculates the difference value between two destination sequence numbers from the received packet and routing table respectively,compares it with the heuristic calculated difference threshold to distinguish whether a node is suspicious,and executes bait detection for suspicious nodes to find and identify the malicious nodes.And then,the malicious nodes are isolated to build a secure and reliable route for data transmission.Simulation results show that,compared with two secure routing protocols including SAODV and ARAN,the AODV routing protocol modified by the new strategy has higher packet delivery rate and more stable transmission performance in the case of different number of nodes,node movement speed and the proportion of malicious nodes.关键词
