Probabilistic Qos Analysis In Wireless Sensor Networks, Yunbo Wang
Probabilistic Qos Analysis In Wireless Sensor Networks, Yunbo Wang
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Emerging applications of wireless sensor networks (WSNs) require real-time quality of service (QoS) guarantees to be provided by the network. Traditional analysis work only focuses on the first-order statistics, such as the mean and the variance of the QoS performance. However, due to unique characteristics of WSNs, a cross-layer probabilistic analysis of QoS performance is essential. In this dissertation, a comprehensive cross-layer probabilistic analysis framework is developed to investigate the probabilistic evaluation and optimization of QoS performance provided by WSNs. In this framework, the distributions of QoS performance metrics are derived, which are natural tools to discover the probabilities to …
