Prioridade Dinâmica de Mensagens Aplicada a Redes de Sensores Corporais Sem-Fio

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