Embodiment Construction

[0028] In Figure 1, a cooperative enhanced system structure based on a trusted central server (Server) and neighbor monitoring is composed of a trusted central server and a group of nodes. These nodes should have interfaces to access the wide-area cellular network, for example, Receive data from GPRS network or send data to GPRS network. Through the wide-area cellular network, it can be connected to the Internet network, thereby accessing a trusted central server (hereinafter referred to as the central server) to verify identity, and other nodes can query the central server for the reputation record of a certain node (user).

[0029] Step 1. Set the initial value of the node's reputation;

[0030] When a new node A wants to join the mobile ad hoc network, it first goes to the central server for login registration and identity verification. The central server is accessed through the node's wide area wireless network interface, which can be managed by the wide area cellular operator...

Abstract

A method of applying cooperation reinforcement mechanism on ab hoc network includes confirming newly joined node reputation initial value of network , monitoring each node behavior and detecting attack from bad node for obtaining their final reputation through evaluation system , confirming node creditability as per its reputation and confirming that node is selfish node if its reputation is lower than threshold , isolating it out from network and informing this to neighbour node , enabling selfish node to increase its reputation through cooperation for joining itself in mobile ab hoc network again .

Description

Technical field [0001] The invention relates to a method for a cooperative enhancement mechanism applied to an ad hoc network. The invention is suitable for the wireless network application field, and is especially suitable for the wireless ad hoc network application field. Background technique [0002] The mobile ad hoc network (MANET) is a temporary network that does not depend on any fixed infrastructure, and uses self-organization for communication. At present, the ad hoc network has received extensive attention from the international academia and industry, and is getting more and more attention. Widespread application has become an important direction for the development of mobile communication technology, and will occupy an important position in the future communication technology. However, due to the limited wireless transmission distance of each mobile node, it is necessary for the nodes to support each other and help forward the packet data packet to the target point. Wh...
