Today's UE devices, such as smartphones, have numerous inbuilt sensor components. For example, the modern mobile operating systems (e.g. Android OS) have provided numerous software components that are capable of integrating both internal and external sensors to support mobile Ambient Assisted Living (AAL) applications such as real-time health monitoring and observing the surrounding environments of the user to avoid dangers. Fundamentally, classic mobile AAL applications rely on the distant cloud to process the sensory data in order to identify situations. However, such an approach is often unable to provide rapid response due to communication latency issues. Therefore, utilizing proximal fog service derived either from the MEC-supported cellular base station or individual or small business-provided Indie Fog [17] has become an ideal solution to enhance the agility of mobile AAL applications [18].
