Abstract

This PhD work aims to show that the abstraction of sensor networks, by means of service-oriented architectures, may impose some performance degradation, but it does not invalidate most applications. The methodology used to conduct this research consists of experiments that realize performance evaluations that analyze the behavior of different mechanisms of exposure of sensor networks, and evaluates the three major services of the Sensor Web Enablement (SWE) model interfaces. The results show significant differences in performance between the methods of considered access. The results also show that the generated overhead is not significant when compared with the frequency of obtaining observations of most wireless sensor networks. Aiming to minimize the performance issues imposed by the SWE framework, an architecture providing quality of service (QoS) called Sensor Web Architecture (SWARCH) is proposed and implemented. A case study of SWARCH demonstrates that it is possible to reduce response times when accessing the SWE services through a Broker that constantly monitors various service providers (AU)
