Semantics-based wireless sensor network service discovery method

Abstract

The invention discloses a semantics-based wireless sensor network service discovery method, which comprises the steps of: S1, abbreviating the semantics-based wireless sensor network service discovery method as SSD; S2, assuming that each node has a unique ID mark; S3, and establishing a service body model based on service scenarios. The semantics-based wireless sensor network service discovery method avoids high deployment cost of a wireless sensor network, and has good coping effect while the requirements for sharing the wireless sensor network in various kinds of applications and reutilizing the wireless sensor network is increasing; the semantics-based wireless sensor network service discovery method adopts a semantics-based service discovery mechanism, and greatly increases a precision ratio of wireless sensor network service discovery; and the semantics-based wireless sensor network service discovery method considers service node attributes and attributes of an environment where a node is positioned besides service itself, and effectively improves service quality. In general, the semantics-based wireless sensor network service discovery method increases the precision ratio of service discovery, and improves service discovery quality.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a semantic-based wireless sensor network service discovery method. Background technique [0002] With the continuous expansion of the application range of wireless sensor networks, people have spent huge sums of money to build a large number of wireless sensor networks, and the cost is high. It is urgent to share the services provided by nodes to improve the application value of wireless sensor networks. Therefore, how to discover and use services in a timely and effective manner in the wireless sensor network is the key to realize the practical application of the wireless sensor network. However, the traditional service discovery method does not consider the characteristics of wireless sensor network itself, so it is not suitable for application in wireless sensor network. [0003] In order to solve the problem of service discovery in wireless sensor networks, ...

AI Technical Summary

Problems solved by technology

[0004] However, the above service discovery methods generally have the following two problems: first, they do not consider semantics, and cannot accurately describe services, resulting in low precision of service discovery

Secondly, they simply consider the service itself, without fully considering the service scenario, and the service quality needs to be further improved. Therefore, we propose a semantic-based WSN service discovery method
