Embodiment Construction

[0053] The working mechanism and specific operation steps of the method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] 1. Routing

[0055] 1. Minimum cost path selection based on VCG mechanism

[0056] 1A. Establish a network topology G{V, E, ω} from source S to destination D by using route discovery method, V={v 1 ,...,v n}, the directed edge (v i , v j ) set E_V*V, and with each edge (v i , v j ) associated weight function ω: E→R, which represents the data packet from node v i to node v j Fees upon delivery.

[0057] 1B. According to the shortest path algorithm, find the shortest cost path from source S to destination D, which is S, 1, ... n, D.

[0058] 1C. According to the VCG mechanism, the compensation for node i on the shortest path is:

[0059] αi:=|SP -(i，i+1) |-|SP\(i, i+1)|. Where|SP -(i，i+1) | indicates the minimum cost path when there is no link (i, i+1), and |SP\(i, i+1)| indicates t...

Abstract

The invention is a paying-based routing and transmitting method in self-organized wireless network, using VCG mechanism and Vickrey auction to make really displaying overhead for network functions become the optimum policy of Ad hoc node, and on the basis that the node really displays the expenses for routing and packet transmission, selecting the optimum expense path; in the packet transmitting course, explicitly considering different expenses on the optimum path when each node transmits packets. And the designed node compensating solution can prevent various cheating behaviors of nodes. And the method simplifies the policy-making space of nodes, implements global target optimization, and relatively symmetrically solves the excitation problem in the Ad hoc network in the economic mode.

Description

technical field [0001] The invention relates to a payment-based routing and forwarding method in a wireless ad hoc network (Wireless Ad Hoc), and belongs to the field of cross-application of wireless network performance improvement and enhancement technology and economic principles in wireless communication. Background technique [0002] In a traditional network, there are generally two types of equipment. The first type of equipment is infrastructure, which ensures the operability of network services. For example, dedicated repeaters, routers, gateways, and servers are all infrastructure category; the second type of equipment is terminal equipment, which use the network on behalf of users, such as mobile phones. Ad hoc network has become a research hotspot in recent years. This interest is primarily driven by some military and commercial applications (making it impractical to build a network infrastructure due to time constraints and resource constraints required to tempor...
