Abstract

The invention discloses a wireless multimedia sensor network design method driven by a subjective interest model, is mainly used for the design and application of a wireless multimedia sensor network and pertains to the cross filed of distributed computing and network communication techniques. The method of the invention designs a network intelligent model according to an action model abstracted from the action characteristics of biocenosis in the nature, can be applied to the design of the multimedia sensor network triggered by multiple events and is characterized by reasonably utilizing and distributing recourses in distributed computing and obtaining effective data of event information sources at a relatively low cost and relatively low time delay, carrying out activity cooperation with other crunodes through an interest degree measurement method and being conducive to centralizing network resources to do an in-depth reporting on an interest event source, effectively carrying out data fusion and abandoning redundant data, carrying out natural evolution towards the network, forming a friend circle facing the event and optimizing the structure of the network.

Description

technical field [0001] The invention is a solution of distributed computing and network communication technology. It is mainly used in the design and application of wireless multimedia sensor networks, and belongs to the interdisciplinary field of distributed computing and network communication technologies. Background technique [0002] With the rapid development and maturity of communication technology, embedded computing technology and sensor technology, miniature sensors with perception, computing and communication capabilities have begun to appear and have attracted great attention. This sensor network can coordinately perceive, collect and process various environmental or monitoring object information in the network coverage area, and release it to users who need this information. The sensor network integrates the logical information world and the real physical world, profoundly changing the way of interaction between man and nature; it can be widely used in military,...
