Abstract
Several routing protocols for Delay-Tolerant Networks (DTNs) can be found in the literature. All these protocols have strengths and weaknesses depending on the usage scenario. Nevertheless, in DTNs, messages are forwarded hop-by-hop autonomously, without an on-line path connecting the source and the destination. This unique characteristic of DTNs allows the routing protocol to be changed on-the-fly while a message traverses the network. The only limitation is that each pair of nodes must share the same routing protocol. If each node is able to choose the best routing protocol based on its context and on the available routing protocols, it is possible to minimize the weaknesses of the chosen protocols. In this way, this article proposes an on-the-fly context-aware routing adaptation method. Each node, independently, chooses the routing protocol to forward a message, based on its own context information and on the routing protocols available at the possible next hops. Thus, in order to explore the strengths of all protocols and reduce their weaknesses, every message can be forwarded from the source to the destination through several different routing protocols, one for each hop if necessary. The feasibility and the efficiency of the proposed method are evaluated through simulations, and the results demonstrate that it is possible to increase the delivery ratio and reduce the delay with a small increase on the overhead.
