5 FN-NoE functional description
5.1 General
The thing-user representing a NoE terminal or a virtual switch in the FN-NoE organizes the thing-
user social community to share experiences or collaborate on problem solving. The thing-user social
community provides intelligent collaboration services to accomplish mission described by a human-
user or by a thing-user. The thing-users configure the thing-user social community related to a specific
domain task, share an experience with another thing-user who has joined the thing-user social
community, and perform specific domain tasks autonomously without human operator intervention.
The thing-user social community has a procedure for consensus decision-making and for distributing
shared information. By discovering coordinated peers, the thing-user will establish a proximal path.
Then the thing-user is provided with the thing-user centric communication service.
5.2 Thing-user social community organization procedure
The thing-user of an NoE terminal or a virtual switch is initially specified with the Profile items
including identities, capability skill sets and mission statement to be accomplished.
After initiation, the thing-user visits well-known resources, like FN-NoE registry, to check whether a
thing-user social community exists for collaborating to accomplish the mission. If the thing-user finds a
coordinator of the thing-user social community with whom to collaborate, the thing-user sends a JOIN
message to the thing-user social community, as shown in Figure 2.
If the thing-user fails to find a thing-user social community, the thing-user organizes its own new
thing-user social community as shown in Figure 1. In this case, the thing-user becomes a community
coordinator. The TSN coordinator specifies the range of TSN and configures the structure of TSN.
The community coordinator searches the FN-NoE registry for the identities of the coordinator and
mission statement. The first community coordinator serves as a cluster coordinator as well, until the
cluster is renewed after joining another thing-user.

5.3 Thing-user social community maintenance procedure
If the thing-user finds a social community coordinator to collaborate on its mission, the thing-user sends
a message to join the social community. The social community coordinator validates the thing-user
and assigns a cluster to join. If the assigned cluster coordinator is not located in the social community
coordinator, the social community coordinator requests the cluster coordinator to accept the thing-
user.

Figure 2 — Sequence chart for thing-user social community join
The community coordinator maintains the clusters and their coordinators. The periodic election of
a cluster coordinator renews the clusters of a social community. Similarly, the periodic election of a
community tier coordinator renews the community tier of a social community. The incumbent cluster
coordinator collects the ballots from the thing-users and selects a new coordinator and reports the
voting result to the new coordinator. The newly elected coordinator announces the voting results to
other thing-users. The incumbent cluster coordinator reports to the community coordinator that a new
cluster coordinator was elected.
When a thing-user leaves a social community, the cluster coordinator updates the list of cluster
members. If the departing thing-user is the last remaining thing-user of the social community, the
thing-user should check out of the FN-NoE registry.

5.4 Thing-user experiences sharing procedure
The experience of a thing-user is captured and shared with the thing-user social community in a
distributed manner. A cluster member may subscribe to an experience report from a certain cluster
member who publishes a captured experience to the subscribed thing-user according to its own
schedule.
The subscription request from a thing-user is reviewed and accepted based on the evaluation of the
subscribing thing-user’s social capital.
The subscription and publishing of experiences is managed at the cluster level.
Figure 4 — Sequence chart for thing-user experience sharing
5.5 Coordinated thing-user discovery procedure
The thing-user starts to search a coordinated peer or peer group to help solve the problem of the thing-
user described in the problem statement. The measure of proximity to a coordinated peer is defined in
the motive statement, mission statement, or capacity statement in the profile. If the thing-user does not
have enough information to specify the proximity measure, it may request the measure to the cluster
coordinator or the TSN coordinator.
The thing-user checks the proximity to subscribed thing-users in the cluster. If the thing-user finds an
appropriate peer thing-user, it sends a request for collaboration to solve a problem. If the thing-user
receives an acceptance of the collaboration request, the thing-user requests to establish the proximal
path to the coordinated thing-user.
If the thing-user fails to find a coordinated thing-user in the cluster, the thing-user starts to search for a
peer in another cluster in the same level of community tier. If the thing-user fails to find a coordinated
thing-user in the community tier In this case, the thing-user attempts to search for a peer in clusters in
the higher tier of community until it discovers a peer.
According to the profile, the proximal path will be established either to the single coordinated thing-
user or the sequentially ordered coordinated thing-users may be established.

5.6 Proximal path establishment procedure
To accomplish a mission collaboratively, when a thing-user finds a thing-user or a thing-user group
belonging to the coordinated peers, the thing-user establishes proximal paths between them depending
