Delay-Sensitive Services QoS Control in Sensor-Based Mass Applications

Wireless sensor networks shift from academic realm to industry. The shifting has been started with private, specialized and business-to-business application, but business-to-customers applications and services come in focus now. In business-to- customers (end users, subscribers) applications, quality of services (QoS) is critical issues as well as scalability and reliability. This paper uses robust three-state Markov model of wireless sensor network to develop probability density function of the service delay for use in modeling of end user sensor based delay-sensitive services from QoS and scalability point of view.
