A service node selection method for IoT mobile perception

Abstract

The invention discloses a mobile perception service node selection method facing to an internet of things. The method concretely comprises the following steps of: (1) carrying out heat calculation aiming at the perception area of a mobile node; (2) finding a mobile perception service node facing to the target perception area; (3) calculating a perception service request link factor; (4) calculating a service factor of the mobile perception service node; and (5) selecting candidate nodes based on the mobile node service factor and the link factor. According to the mobile perception service node selection method, the proper service node can be found and selected in the movable, heterogeneous and dynamic environment, so that effective and reliable perception service is provided for a user; and therefore, the mobile perception service efficiency is further improved, and the perception gap can be filled up in the environment of the internet of things.

Description

Technical field [0001] The present invention belongs to the technical field of the Internet of Things, and relates to a method for selecting candidate nodes for mobile sensing service in a target area, which is suitable for social computing, pervasive computing, Adhoc (mobile self-organizing network), and mobile-oriented Internet of Things. A large-scale open distributed application. Background technique [0002] With the rapid development of sensing technology, embedded technology, wireless communication technology, high-performance computing and other related fields, the Internet of Things (Internet of Things) has emerged as a new generation of intelligent Internet. It uses the RFID architecture and wireless sensor network as the basis of perception, realizes data transmission and sharing through the integration of the Internet, and uses high-performance computing technology to realize information management and decision-making. The proposal of the Internet of Things has been ...

Problems solved by technology

[0005] Based on the above analysis, we found that: (1) Existing service discovery is based on unfamiliar nodes, without considering the social and trust relationships between nodes, and usually simply setting them as fixed nodes and ignoring their own attributes; ( 2) In the existing mobile ad-hoc network, considering the limited communication radius, the interaction between nodes is completed through multiple hops. With the continuous popularization of smart devices such as mobile phones, any node can realize interconnection and intercommunication. , which greatly exceeds the communication radius between nodes

In addition, in the process of service node selection, usually the focus is on the node itself, without considering the service relevance between nodes and the historical service attributes of nodes
