Context The increase in the population aging has brought more significant concern about how proper care will be provided to the elderly in the future. Thus, the development of technological solutions for the health domain has gained more prominence. Joining this scenario to the growing use of mobile devices for daily activities, several mobile applications focused on the elderly healthcare have been developed with healthcare and software engineer professionals involved. However, there is no survey to help both professionals to take decisions on the target of application, elderly profile, empirical validation techniques, among others. Thus, the following question arises: how have mobile applications for elderly healthcare been addressed in the literature in the past years? Objective To identify the state of the art in the literature concerned with the development of mobile applications for elderly healthcare, considering healthcare and software Engineering viewpoints. Method We performed a systematic mapping conducted by health and software engineering researchers to provide an interdisciplinary investigation of the papers that address mobile applications for elderly healthcare, summarizing the data collected under the following classification: target of application, older adult profile, spatial-temporal distribution, techniques for empirical validation and type of software engineering research. Results We found a total of 2533 papers and, after applying our eligibility criteria, we got 149. We observed aspects related to the digital health initiative type, using the classification proposed by the World Health Organization (WHO), the elderly profile prioritized by the application, the spatial-temporal distribution of the studies, the empirical validation type, and the research contribution of each analyzed paper to the software engineering area. Conclusions Regarding the WHO classification, we noticed that two categories were more frequently found, Clients and Data Services, and that none of the mobile apps were classified in the Health System Manager category. The data extraction result also reveals that most of the applications found in the literature focused on the independent elderly. Moreover, we observed that most of the studies were proposals of solutions for elderly health and the validation process of these solutions generally consisted of controlled experiments and usability evaluations. At last, the research focused on mobile applications for elderly healthcare has been performed mostly by developed countries.

Future 5G services rely on effective end‐to‐end management and orchestration for consistently obtaining 5G network's performance benefits. vCDN systems, which are core to the efficient delivery of multimedia contents, must thus be redesigned accounting for NFV and Service‐based 5G Core for fully enabling optimal infrastructure resource optimization and the Quality of Service for increasingly demanding immersive services. This article proposes a novel orchestration framework for deep and 5G‐enabled vCDN services, and builds on two main capabilities: a) the dynamic provisioning of vCDN Edge nodes, enabling content placement at the network Edge based on nearby user's presence, and b) Preemptive video content placement, for users rapidly moving between different edge regions. The solution was modeled and validated using ONAP.
