Simple Usage Scenario. A simple scenario is when two mobile smart-phone users meet and engage into a SCAMPI interaction.

Figure 2 presents a simplified situation where two SCAMPI users opportunistically meet and share resources. One user possesses resources for location and communications while the other user has resources only for communications. The user with the location resources then composes a location sharing service and declares this as a SCAMPI service that is accessible for users in the proximity. The other user without local location resources can then access the location information through the declared SCAMPI service. In a more realistic scenario, the set or resources are richer in a single SCAMPI device. The number of users involved in the resource sharing can also be significantly larger, for example, several participants in a concert or in a sports event.
