One of the most important and yet challenging issues in body area networks (BANs) is to provide diverse quality service (QoS). Most physiological data monitoring applications require low rate periodic reporting while real-time entertainment high continuous streaming. Emergency alarm, time-critical but unpredictable data, must be delivered instantaneously. A BAN should satisfy these requirements since each with distinctive QoS requirement may run simultaneously. We propose PNP-MAC protocol...
