Embodiment 1

[0061] Embodiment one: see figure 1 As shown, the network contains a group of nodes and a third-party trust agency TP. TP can be fixed or mobile, and it usually has more resources and stronger processing power than ordinary nodes in the network.

[0062] see figure 2 As shown, in step 201, during a data packet delivery process, the source node subtracts AVG_L units from the amount of virtual currency it owns. If the amount of virtual currency owned by the node is less than AVG_L, the node is not allowed to send data packets.

[0063] In step 202, during the transmission of a data packet, the intermediate node increases the amount of virtual currency it owns by 1 unit.

[0064] In step 203, during the transmission of a certain data packet, the amount of virtual currency owned by the destination node remains unchanged.

[0065] see image 3 As shown, the initialization stage: when the network is initialized, the nodes have a certain amount of virtual currency.

[0066] Mi...

Embodiment 2

[0106] Embodiment two: see Figure 6 As shown, node 1 sends 20 data packets to node 5.

[0107] see Figure 7 As shown, 701, 702, 703, 704 and 705 are respectively the node 1, node 2, node 3, node 4 and node 5 in the construction of Figure 6 A session report for the session shown. TP constructs from the session report Figure 6 The session linked lists of the shown sessions are respectively 706, 707 and 708. 706 is a suspicious session linked list, and 707 and 708 are normal session linked lists.

[0108] Assuming AVG_L=5, the node updates the local virtual currency: the virtual currency of node 1 is reduced by 5×20=100 units, the virtual currency of node 2 is increased by 9 units, the virtual currency of node 3 is increased by 10 units, and the virtual currency of node 4 is increased by 10 units. The currency increases by 19 units, and the virtual currency of node 5 remains unchanged.

[0109] TP updates the virtual currency of the node: the virtual currency of node 1 i...

Abstract

The invention discloses an excitation method and system for cooperation of data forwarding of self-governing nodes of an Ad hoc network. A micro-payment means is utilized to excite the self-governing nodes in the Ad hoc network to carry out data forwarding and to set the behavior of a third party confidence mechanism TP for supervising the nodes to manage virtual currency, the nodes with unusual behaviors are detected and isolated, the TP can construct conversation chain table assemblies according to conversation reports, and dependency for specific type DSR routing protocols is overcome. According to the excitation method and system, IP address identifications of source nodes and target nodes are utilized to have conversations, and the system can be compatible with the routing protocols of any types.

Description

technical field [0001] The invention relates to a method and system for promoting network node cooperation, in particular to an incentive method and system for enhancing data forwarding cooperation of Ad hoc network autonomous nodes. Background technique [0002] Ad hoc network is a self-organizing network. The nodes in the network are equal and can move freely. Therefore, the topology of the network is constantly changing, and the various resources of nodes, such as energy and memory, are very limited. Compared with wireless networks, Adhoc networks are characterized by autonomy and multi-hop forwarding. Since there is no central management node, all functions of the network are completed through the cooperation of autonomous node data forwarding. Multi-hop forwarding enables nodes outside the signal coverage of each other to communicate through the cooperation of intermediate nodes, expanding the coverage area of ​​the network. [0003] In the Ad hoc network, the establi...
