Abstract:
A Biomedical Wireless Sensor Network (BWSN) is a special Wireless Sensor Network (WSN) with a small number of nodes designed for medical applications. These networks must ensure that medical data is delivered reliably and efficiently, in order to fulfil a set of pre-established Quality of Service (QoS) requirements. In this way, the research community have been proposing new solutions to improve QoS in WSN, namely in routing protocols and power consumption efficiency. However, there still a need for appropriate QoS guaranties in BWSN. In this paper, possible QoS requirements of BWSN are discussed, together with a framework to automatically evaluate the performance of such QoS techniques. That framework was used together with simulators and operating systems appropriate for WSN, COOJA and Contiki OS, and proved to be a valuable tool for a proper evaluation of QoS parameters and metrics.
