Self-networking node coordination and trust method based on two-way quantitative evaluation in ubiquitous computing

Abstract

The invention provides a self-networking node coordination and trust method based on two-way quantitative evaluation in ubiquitous computing. The method comprises the following steps of: adjusting coordination in message transferring based on an evaluating credit value; calculating an evaluating credit value S under ready consumption though a node of a sending side based on a sending coordination mechanism; determining an evaluating credit value R to be promoted through the node of a receiving side based on receiving the coordination mechanism; if S is not less than R, reaching a trust between two sides, and determining that a final evaluating credit value for consumption and promoting is (S+R) / 2, otherwise, determining that the coordination between the two sides fails. With adoption of the method, the coordination of nodes can be effectively excited; an excellent message transmitting rate and time delay can be achieved at a limited resource condition in the ubiquitous computing, and resource consumption can be actively promoted to be reduced; and moreover, the method can effectively solve the problem due to block caused by blind coordination of the nodes to a performance of a network.

Description

technical field [0001] The invention relates to an ad hoc network node forwarding and interaction technology, in particular to an ad hoc network node coordination and trust enhancement technology, in particular to an ad hoc network node coordination and trust method based on bidirectional quantitative evaluation in a ubiquitous environment. Background technique [0002] In 1991, the concept of "Ubiquitous Computing" (Ubiquitous Computing) was proposed by the computer scientists of Xerox Laboratory, which describes that anyone can connect to the network through suitable terminal equipment anytime and anywhere to obtain personalized information services. A new information environment. Since then, on the basis of "ubiquitous computing", Japan and South Korea proposed "Ubiquitous Network" (U-biquitous Network), the European Union proposed "Am-bient Intelligence", and the United States proposed "Ubiquitous Network". Ubiq-uitous Knowledge Environment” (Ubiq-uitous Knowledge Envir...

Problems solved by technology

The disadvantage of this solution is that in the real ubiquitous environment, there is very little transmission of the same amount of data, which has a certain degree of blindness, and it is difficult to improve network performance.
