Abstract

The invention discloses a virtual subnet partition method based on node reputation values in a mobile ad hoc network, provides the mapping relation between node security levels and the reputation values, provides a secure routing scheme based on physical subnets plus virtual subnets and aims at realizing isolation of data with different service levels and information sharing among nodes with different security levels. The technical scheme is as follows: carrying out physical subnet partition according to a network topological structure, then initiating the calculation of the node reputation values from the cluster head and further generating the virtual subnets. The active routing way is adopted in the physical subnets, the on-demand routing way is adopted in the virtual subnets, and the isolation of malicious nodes from selfish nodes is realized by updating the node reputation values. By adopting the method, the security and the confidentiality of information transfer in the mobile ad hoc network can be improved.

Description

technical field

[0001] The invention relates to the isolation control and security protection of node data of different security levels in a mobile ad hoc network (Mobile Ad Hoc Network, MANET), in particular to an isolation control method using a virtual subnet based on reputation. Background technique

[0002] MANET originated from military applications. After years of research and development, its application targets have been expanded to civilian fields such as home networks and personal wireless mobile communications. Ad hoc network is a wireless communication network composed of a group of mobile nodes with wireless transceiver devices. It does not depend on the preset infrastructure and is temporarily established. When not within the communication range of each other, other intermediate nodes can be used to forward information to complete multi-hop communication, so it is also called packet wireless network or multi-hop network. Mobile nodes and data in MANET have di...
