Context Aware Computing for Ambient Assisted Living

With the prevalence of wireless technologies, cloud computing and the rapid growth of deployed smart sensors in the past few years, we live in an increasingly interconnected world. These technologies have fostered the dissemination of the Internet of Things (IoT). They form the foundation for smart homes and smart cities. Context aware devices and ambient computing techniques have expanded the application of the IoT into new areas such as assisted living, eHealth, and elderly care. However, there are challenges to analyze the large volumes of sensor and context data generated by these devices. Also, there are serious security and privacy concerns especially in the area of health care that need to be addressed. This paper gives an overview of the state-of-the-art technologies for ambient assisted living (AAL) and proposes an architecture based on SOA.
