Ambient Assisted Living (AAL) is a concept that seeks to provide most autonomy, security, and health services for elderly people offering technology solutions to them. When AAL applications are provided through the Internet, it is possible to create new applications involving the concept of Internet of Things (IoT). The AAL-IoT applications can be used to event detection (such as fall detection or blood pressure) and send messages to an emergency service or a family member through the Internet. The event detection is frequently performed by sensor networks. However, these networks can present some difficulties to provide the high quality of service required for AAL-IoT applications. Thus, this paper proposes a new routing metric that considers information about the nodes and their connections, seeking the network performance enhancement for AAL-IoT. The proposed metric is an additive composition of information about link quality and nodes energy. The results obtained through simulation show that the proposed routing metric can increase the network performance to better meet the AAL-IoT requirements.
