Abstract
The growing demand for wireless sensor applications in many ways has made QoS one of the most important issues in wireless sensor applications. Ensuring quality of service in wireless sensor networks (WSNs) is very difficult because the available resources of the sensors and the different applications running on these networks have different limits in terms of their nature and requirements. Traditionally, quality of service has been concentrated at the network level, paying attention to measures such as latency, productivity, and instability. In this document, we provide the appropriate WSN standards, including services, responsibilities, and availability, and ultimately facilitate the submission of qualified services. We discussed QoS comparisons and then proposed three important quality factors that should be considered when developing WSN service quality services: availability, reliability, and retention. We are experimenting with its three phenomena (reliability, availability, and maintainability-RAS) to demonstrate how to effectively access quality of service (QoS) to improve the reliability of WSN.
