Abstract:

Delay and Disruption Tolerant Networking is extremely useful when source and destination nodes are intermittently connected.
Active DTN introduces software code to improve DTN performance. DTN implementations use application-specific routing algorithms to overcome those limitations. However, current implementations do not support the concurrent execution of several routing algorithms. A solution to this problem is extending the messages being communicated by incorporating software code for forwarding, delivery, lifetime control and prioritisation purposes. Our proposal stems from the idea of moving the routing/delivery algorithms from the host to the message. This solution is compatible with Bundle Protocol (BP) and facilitates the deployment of applications with new routing and delivery needs. Additionally, a secure geographic routing protocol that learns about the mobility habits of the nodes of the network will be presented. This routing protocol uses information about the usual whereabouts of the nodes to make optimal routing decisions and makes use of homomorphic cryptographic techniques from secure multi-party computation to preserve nodes’ privacy while taking routing decisions.
