Abstract: Low power and small footprint IEEE 802.15.4/ZigBee based devices are a promising alternative to 802.11a/b/g and proprietary protocols for non-critical patient monitoring under important scenarios such as post-op and emergency rooms. However, their use in a healthcare facility to monitor several mobile patients poses several difficulties, mainly because these protocols were primarily designed to operate in low traffic load scenarios. This work presents simulation results used to evaluate the performance of an I… Show more

“…The ZigBee protocol has been successfully employed on several sensing applications in spite of the lack of quality-of-service (QoS) guarantees. Since it is based on carrier sense medium access (CSMA), it is susceptible to collisions even in lowtraffic scenarios [19]. Additionally, CSMA-based protocols are susceptible to the hidden-node problem, where some traffic being sent to a receiver may not be detected by another transmitter [6].…”

“…In [4] we have estimated, based on simulations, the performance of ZigBee WSNs designed for continuous vital signs monitoring. These networks were evaluated in terms of scalability considering different topologies.…”
