The Wireless Body Area Networks (WBANs) are a special case ofthe Wireless Sensor Networks (WSNs) and, in general, are responsiblefor gathering and transmitting biometric data from a givenpatient. One of the features of the WSNs is the self–configuration;i.e., the capability that a given parameter can be adjusted regardingsome occurrence in execution time. As stated, the objective of theWBANs is the gathering, through several sensors, of biometric dataof a patient. In general, because of possible daily activities and/orpathologies, some sensors can be more demanded (or required) incertain periods of the day. In these situations, information of thesementioned sensors are more relevant and require larger data deliverypriority. Thus, we propose QoSBody-AODV, a variation of theAODV routing protocol, which performs the dynamic adjustmentof the message’s priority, turning the network functioning to besensitive to the physical activities performed by the patient, as wellas pathological information.
