Using Combined Cellular Ad Hoc Communications for Smart Environments

We propose a Heterogeneous Multi Domain (HMD) architecture and protocols that uses ad hoc and cellular communications for enabling the exchange of information among users and smart environments. In particular, we focuss on the data communication and information diffusion related to tourism industry. Sensor´s technology enables today the collection of various data related to the environment, such as temperature, location, and so on. This information can be delivered timely to users interacting with the environment. For example, a user might get direction in a building or in a park. Our architecture uses a network of gateways as an hierarchical virtual infrastructure to interconnect various network domains. Gateways are responsible for translation among different communication protocols, including routing, signalling, and security. HMD architecture is scalable, flexible and adaptive to QoS needs for interdomain communications. The protocol goal is to optimize such communications in terms of performance.
