“…Mobile code along with message state has proven to be a good combination in a variety of settings. In [3] software code and message state are presented to improve OppNet performance. The authors provide a solution that consists in extending the messages being communicated by incorporating software code for forwarding, delivery, lifetime control, and prioritisation purposes.…”

“…In this experimentation, for both scenarios, we simulate a group of different nodes that form a communication network similar in attributes as the one proposed in [3], a study of an intermittently connected emergency scenario. In the two different areas presented in the previous section, different nodes with six different node target profiles share the network.…”

“…For the sake of simulation accuracy, we have performed the simulations presented in this sections following the behaviour and performance of a real Bundle Protocol implementation capable of reproducing the Explore and Wait delivery scheme. We base our simulations on Active-DTN [3], a DTN solution 9 that consists in extending the Bundle Protocol messages being communicated by incorporating software and message state for forwarding, delivery, lifetime control and prioritisation purposes.…”

“…Finally, we present different useful applications and a wide set of simulations in two different scenarios: an urban and a rural scenario. We base our simulations on Active-DTN [3,2], an implementation of the Bundle Protocol that allows bundles to have an active routing and delivery behaviour. Active-DTN allows applications to send Relcast bundles by including within the bundle their delivery protocols as bundle extensions implemented with mobile code.…”

In the context of Opportunistic Networking (OppNet), designing routing and delivery protocols is currently an open and active line of research. In some OppNet scenarios, destination addresses are not always known by sending applications. Profile-cast models solve this problem by allowing message destinations to be users or groups of users defined by their profiles. These profiles provide very effective ways of characterizing nodes in terms of node's attributes such as their profession, interests or typical whereabouts, for example. However, there are strong limitations in OppNet Profile-casting. There is no current way of representing special profiles defined by relative delivery functions such as best, maximum or over-the-average: nodes belong to these relative profiles taking into account not only attributes from the very same node but also relative to others from the same profile. In this article, we introduce Relcast, a Profile-cast model that allows messages to be sent to profiles defined in terms of relative delivery functions. Additionally, we present Explore and Wait, a composite routing-delivery scheme that uses optimal stopping theory-based delivery strategies to route Relcast messages. We show, using simulations that this routing-delivery scheme performs better than traditional approaches that use state-of-the-art routing-delivery primitives.

“…Active-DTN (or aDTN for short) is a Bundle Protocol [40] compliant open-source middleware system that can help meet the different needs of multiple applications that share the same wireless network, by allowing these applications to specify how their messages should be processed while traversing the network [41]. aDTN extends the structure of bundles so they can carry routing code together with plain data.…”

Conflict-Free Replicated Data Types (CRDTs) are data types that can be used in distributed systems when optimistic replication is tolerable. Replicas can be updated locally, without coordination, and consistency is obtained eventually by asynchronously propagating updates among replicas. Because CRDTs can tolerate asynchronous transmissions, they can serve as software elements in opportunistic networks (OppNets), where the dissemination of information is dependent on unplanned transient radio contacts between mobile nodes. In this paper we investigate the problem of implementing operation-based, state-based, and delta-state-based CRDTs in OppNets. A contact-driven synchronization algorithm is proposed for each kind of CRDT, and experiments based on realistic tracesets are conducted in order to compare how these algorithms can perform in an OppNet. Experimental results show that delta-state-based CRDTs globally outperforms operation-based and pure state-based CRDTs, especially when considering the number of messages required to ensure the synchronization of replicas.
