We present a novel mechanism intended to provide Quality of Service (QoS) for IEEE 802.15.4-based Wireless Body Sensor Networks (WBSN) used for pervasive healthcare applications. The mechanism was implemented and validated on the AquisGrain WBSN platform. Our results show that the QoS performance of the IEEE 802.15.4 standard can be considerably improved in terms of reliability and timeliness for intra-node as well as inter-node scenarios while keeping backward compatibility to ensure interoperability.
