Future Smart Cities require new ways to manage services that benefit the end users. An important issue is how to connect homes in a community and create an alert management system in Smart Cities with coordination among different entities. In this paper, we present an architectural vision of a software defined home alert management system for Smart Cities. This alert management system would make the residents aware of any incidents in the neighborhood such as fire. In this work, we use the features of software defined networking to design a manageable and flexible smart home for a smart community to provide services such as smart alarm systems.
